The SeaMAX Suite is a collection of configuration/diagnostic utilities and software libraries that enable rapid application development. The SeaMAX API, included in the SeaMAX Suite, provides a common API for Sealevel SeaI/O and SeaDAC data acquisition modules. SeaMAX is designed to simplify application development by requiring little knowledge of the underlying communication protocols of these devices and replacing low-level programming.
Proceed with installing the SeaMAX Software Suite using the software disk that was included with your Sealevel I/O module. Software drivers are also available on the product webpage on the Sealevel website at www.sealevel.com. Do not connect the I/O module to the host until the software is installed. To install Sealevel Systems software, you must log in as an administrator or have administrator privileges in Windows. 1. Insert the Sealevel Systems disk in to your optical drive. 2.
5. Type the part number for your adapter in the text box and click „Enter‟, or click on the drop box to scroll from the listing to select your product. If you installed your hardware prior to loading/installing the drivers, please click on the „Click here if you installed hardware before software‟ button and follow the listed instructions. 6. Click the „Install Drivers‟ button to launch the Installation Wizard. 7.
1. To install the driver executable from the Sealevel disk, browse the Sealevel Systems disk for: Software\SeaIO\Windows\SeaIO Installer.exe 2. If you are using Windows Vista or newer operating systems, right click on the installer executable and choose ‟Run as Administrator‟. If you are using an operating system prior to Windows Vista, double click on the executable to launch the Installshield and initiate the driver installation. 3.
4. In the Device Manager under „Action‟, choose „Scan for hardware changes‟. This will prompt the installation of the adapter and associate it with the newly installed SeaIO driver. If you are using a Wireless (W-series) or Ethernet (E-series) SeaI/O module, skip ahead to either the Configuring a Wireless Module or Configuring an Ethernet Module sections of this manual, before using MaxSSD. ©Sealevel Systems, Inc.
The Sealevel Systems configuration utility, MaxSSD, is designed to simplify the installation, configuration, and diagnostics of Sealevel I/O modules. MaxSSD is a Microsoft Windows application and has been tested with Windows 2000, XP, Vista and Windows 7. When you run the MaxSSD utility (Start All Programs Sealevel SeaMAX MaxSSD) it will default to the “Host PC Configuration” tab. This tab allows the user to choose the initial communication settings for the connected I/O device.
Once the host computer is configured correctly, the “SeaI/O Configuration” tab becomes available. Before communicating with a SeaI/O module, the configuration utility must determine if there is an I/O module at that slave ID address, and if so, what type of module it is. This is the purpose of the Get operation. To perform a Get operation, first select the slave ID to which the module is configured.
After the Get command is executed, the “Module Description” frame will display the model type, description, firmware version number, interface, and I/O type. In the example shown, the module found at slave ID 247 is a SeaI/O-420 module with a USB (Modbus RTU) interface. The “Set Settings” and “Change Slave ID” buttons will also be enabled for this module. After a successful Get operation, additional tabs may be displayed in MaxSSD, depending on the found device model.
The broadcast feature sets the Ethernet SeaI/O (E-series) module‟s TCP/IP to RS-485 translation data rate independently of the SeaI/O module itself. If you set the data rate to 115.2K bps via a MaxSSD broadcast command, both the RS-485 port and the Ethernet port will respond thereafter to 115.2K bps, as expected.
The “Digital IO” tab of MaxSSD is displayed when using Sealevel I/O devices featuring discrete inputs and outputs. It displays the device‟s current input and/or output status in an intuitive and usable manner. When displaying SeaI/O, the “Digital IO” tab displays inputs and outputs in groupings (or banks) of eight. Therefore, a Sealevel I/O device with 16 inputs and 8 outputs would show two banks of inputs and one bank of outputs.
The “A/D Inputs” tab displays the current state of the analog-to-digital channels for Sealevel I/O devices that feature A/D inputs. Settings are provided for both device wide and per-channel configuration. The “Device Configuration” selection drop-box adjusts the arrangement and function of the A/D input channels. Input channels are displayed as banks (groups of eight). Each channel is range configurable via the voltage range dropdown list.
The “D/A Outputs” tab is useful for manually setting the digital to analog output voltages on applicable Sealevel I/O devices with D/A channels. A preliminary diagnostics utility (see following page) has been provided to verify proper hardware functionality. The D/A outputs of the SeaI/O-470 are factory set for 0-10V. To configure the D/A outputs for 0-5V, you will need to open the enclosure and set the correct jumpers.
To check basic functionality of both the A/D and D/A converters, press the “Diagnostics Utility” button on the “D/A Outputs” tab (shown on the previous page) and then press the “Start” button, as shown below. Any errors will be shown in the “Results” pane. If any errors occur, please contact technical support for further help. To properly use the values returned from the SeaI/O-470 module‟s A/D channels, the application program must convert the returned values to engineering units (voltage).
Following these simple steps can eliminate most common problems. 1. Read this manual thoroughly before attempting to install the device in your system. 2. Uninstall any previous versions of the SeaMAX software before installing any new versions. 3. Install SeaMAX software before connecting any Sealevel I/O devices. Installing the software places the necessary files in the proper locations on your system. After installing the software, proceed with adding the hardware. 4.
Problem: The SeaI/O module starts up with a strange IP address (i.e., 169.254.x.x). All Ethernet (E-series) and Wireless (W-series) SeaI/O modules are shipped with DHCP enabled. If no DHCP server is available or the DHCP server cannot be reached, Ethernet SeaI/O modules default to a random IP address in the range 169.254.x.x. Wireless SeaI/O modules default to a random IP address in the range 192.168.0.x. Change the PC‟s network settings to place both the SeaI/O module and PC on the same subnet.
Before configuring SeaI/O modules using MaxSSD, you must first select a device addressing method. Next, you must properly set termination and pull-up/pull-down resistors. Finally, you must configure the SeaI/O modules one at a time before MaxSSD and any subsequent applications (using the SeaMAX API) will be able to successfully communicate. SeaI/O modules have a rotary switch, labeled “ADDR”, located on the left side of the device that is used to set the device address (slave ID).
A “stack” or “chain” of SeaI/O modules, connected via the pass-through connectors or screw terminals on the left side of the enclosure, communicates via an RS-485 bus, which must be properly terminated to work correctly. A set of three dipswitches is located on the left side of enclosure, next to the “ADDR” rotary switch. These switches control line termination and the RS-485 pull-up and pull-down resistors.
Once the SeaMAX Software Suite has been installed successfully and you have decided which address (slave ID) method you intend to use, start by connecting the first SeaI/O module to your computer. This will be referred to as the “base” module. If you are chaining multiple SeaI/O modules together, only one SeaI/O module in the chain can be the “base”. All other SeaI/O modules connected to the “base” module are referred to as expansion modules.
Once you have successfully connected and communicated with a “base” module, you can begin adding expansion modules (N-series). Connect a single expansion module to the “base” module via the RJ45 pass-through connectors or screw terminals on the left side of the enclosure. Expansion modules include a convenient 5” interconnect cable (Part# CA239) to simplify daisy-chaining SeaI/O modules together. Alternately, you can use standard network patch cables to chain expansion modules to a “base” module.
This section applies only to Wireless (W-series) SeaI/O modules. For all other SeaI/O modules, refer to the Configuring a “Base” SeaI/O Module and Configuring Expansion Modules sections on the previous pages. Start by connecting power to the wireless SeaI/O module. The LEDs will blink to confirm that the unit is powered up and is ready to be configured to work with your wireless network.
Verify that SeaMAX software has been installed successfully and that a wireless SeaI/O module is connected to power and ready to be configured to communicate with your wireless network. This module will become the “base” module. To configure a wireless SeaI/O module, you must be using a laptop or desktop computer with a wireless 802.11b/g compatible adapter. The security settings on many wireless access points (WAP) prevent you from seeing Ad Hoc devices by default.
Start by opening the Windows Wireless Network Connection utility, which can be found by clicking the Start button and hovering over My Network Places. Right-click on My Network Places and then select Properties from the menu. You should see a Wireless Network Connection listed in the new window that opens up. Right-click on your wireless network connection and select „View Available Wireless Networks‟ from the menu.
The Wireless Network Connection window will now display “Limited or no connectivity” next to the “SL_Recovery” network connection. All wireless SeaI/O modules are shipped with DHCP enabled. When you first connect a wireless SeaI/O module to the network, the status LEDs on the front of the module will blink while it searches for a DHCP server.
Start the Ethernet Config utility (Start All Programs Sealevel SeaMAX Ethernet Config) installed with SeaMAX. In the „Available SeaI/O Devices‟ pane, you should see a “SeaIO Wireless” module listed under Model, as shown below. If the module doesn‟t show up, click the “Search for SeaI/O Devices” button. The „Available SeaI/O Devices‟ pane should refresh with any Ethernet or Wireless SeaI/O modules that are found on the network.
You must now change the IP Address of your wireless adapter to match the subnet (first 3 octets) of the wireless SeaI/O module listed in Ethernet Config. You can change your wireless adapter's IP Address by going to the Properties dialog for your wireless adapter (Start Settings Network Connections). Right-click on your network adapter and then select Properties from the menu. This opens the Wireless Network Connection Properties window.
In the Internet Protocol (TCP/IP) Properties window, click the radio button for „Use the following IP Address‟. The first 3 octets of the IP address must match the IP address displayed for the wireless SeaI/O module. The last octet must be different. In this example, the last octet for the wireless SeaI/O module is 32 and we configured the last octet for the wireless adapter to 55. Click the OK button in this window. Click the OK button on the Wireless Network Connection Properties window.
To confirm that the IP Address for your wireless adapter was changed successfully, reopen Ethernet Config (Start All Programs Sealevel SeaMAX Ethernet Config). You should now see the wireless SeaI/O module‟s „Name‟ listed (“DemoUnit” in this example). This indicates that your wireless adapter and the wireless SeaI/O module are on the same subnet and you are now able to communicate with the wireless SeaI/O module. Do not make any changes to the „Device Network Settings‟ at this point.
Now that you can communicate with the wireless SeaI/O module, the Wireless Configuration settings window will open, as shown. ©Sealevel Systems, Inc.
You can now change the Network SSID, Topology, Channel, and Security Settings to match your wireless network. After making your changes and clicking OK, the device will reboot and take up to 20 seconds to appear on the network using your new settings. If you change the SSID and/or network Topology and/or Channel, you‟ll have to reconnect to the SeaI/O module. Close Ethernet Config for now. The supported wireless configuration settings are detailed on the following page.
The following options are available in the Wireless Configuration window: Wireless Configuration Default Settings Available Options Network SSID SL_Recovery Alphanumeric Case Sensitive 32 Characters Topology Ad Hoc Ad Hoc Infrastructure Channel [Varies] 1 – 11 (US) 1 – 14 (Europe, Japan) Security Settings No Security Enabled (Ad Hoc Mode) No Security Enabled 64-bit Open WEP 64-bit Shared WEP 128-bit Open WEP 128-bit Shared WEP Security Settings No Security Enabled (Infrastructure Mode) No
using the steps described at the beginning of this section. Depending on the country used, it may take several reset cycles to get the unit back to a channel valid for your region. Use the Wireless Configuration window to change channels, if possible. The Key Encoding method can be either a Passphrase or a Hexadecimal Key, if using a WEP variant. If you are using a WPA variant, then the Key Encoding method is Passphrase. Different security encryption methods require different Network Key types and lengths.
Open the Wireless Network Connection utility again (Start right-click on My Network Places select Properties from the menu. In the next window, right-click on your wireless network connection select „View Available Wireless Networks‟ from the menu). Select the SSID for your wireless network and click the “Connect” button. The wireless SeaI/O module will no longer be visible since you configured it to work with your wireless network in the previous step.
To complete the configuration, you need to change the IP Address of your wireless adapter back to its original settings. Open the Network Connections utility (Start Settings Network Connections). Right-click on your network adapter and select Properties. On the General tab, select „Internet Protocol (TCP/IP)‟, leave the box checked, and then click the Properties button.
Start MaxSSD (Start All Programs Sealevel SeaMAX MaxSSD) and select Ethernet in the drop down box. Verify that the IP Address for the wireless SeaI/O module appears in the right hand pane. Choose the correct IP Address (if more than one is listed) and click the “SeaI/O Configuration” tab. Use the drop down box to select the appropriate Slave ID (default is 247) and the click the “Get SeaI/O Module Settings” button.
Set the slave ID of the “base” wireless SeaI/O module using the rotary switch or software selection method discussed in the Setting Device Address section (MaxSSD chapter) of this manual. This guarantees that any expansion modules connected next will not conflict with the “base” module. Perform another Get operation to verify that you can communicate with the “base” wireless SeaI/O module at the new slave ID. Configure the SeaI/O modules one at a time.
SeaI/O wireless (W-series) modules are compatible with 802.11b and 802.11g wireless networking equipment operating in the 2.4GHz frequency spectrum. The wireless modules can operate over any of the 14 available channels, defined by the IEEE 802.11 specification, listed by country below. These regulations are subject to change at any time.

This section applies only to Ethernet (E-series) SeaI/O modules. For all other SeaI/O modules, refer to the Configuring a “Base” SeaI/O Module and Configuring Expansion Modules sections on the previous pages. Verify that SeaMAX software has been installed successfully and that an Ethernet SeaI/O module is connected directly to your computer using the yellow crossover cable supplied with your module. This module will become the “base” module. All Ethernet SeaI/O modules are shipped with DHCP enabled.
Start MaxSSD (Start All Programs Sealevel SeaMAX MaxSSD) and choose the correct IP address to communicate with the “base” Ethernet SeaI/O module. Ensure a successful Get operation (refer to the MaxSSD section of this manual for more information). Set the slave ID of the “base” Ethernet SeaI/O module using the rotary switch or software selection method discussed in the Setting Device Address section on the previous pages.
Before recovery begins, make certain that the PC and Ethernet SeaI/O module are on the same network segment – they should be connected with an Ethernet crossover cable, through a hub, or through a non-routing switch. Ethernet SeaI/O modules are shipped with both an Ethernet patch cable (blue) and an Ethernet crossover cable (yellow). Enter the MAC address found on the label on the bottom of the SeaI/O enclosure. A MAC address is made up of six pairs of hex digits separated by dashes (i.e.
The initial version of the firmware does not support theses Advanced Features. These units will report their version number as “1”. Starting with version “2” support for these Advanced Features was implemented. You may determine the version of your SeaIO device using the MODBUS command FUNC_SEAMAX_GET_EXTENDED_INFO (0x66), or by viewing the device info in MaxSSD, shown below.
Since SeaIOCU.exe must be executed from a command prompt, the easiest way to use it is to copy SeaIOCU.exe and the hex file (in this example it is 420E.hex) to a subdirectory you create. For this example, we will create a subdirectory called c:\seaiocu. Click on Start, then click Run and type “cmd” (without the quotation marks and hit enter. You will then see a command prompt (c:\documents and settings\name>).
Disabling the Rotary Address Switch and Limiting Software Address Range Selection is not available on older SeaI/O units (Before Firmware Version 2). In addition, the following modules do not support it: 462 463 470 As noted earlier, rotating the rotary switch from a non-zero address to the address zero position will reset the unit to the default state of address 247 and 9600 baud. There are many situations where this is not desirable.
Limiting Expansion Port Communications Data Rate Selection is not available on older SeaI/O units (Before Firmware Version 2). In addition, the following modules do not support it: 462 463 470 There are situations where it is desirable to limit the range of allowable data rates or lock down the unit to one specific data rate. This can be performed by sending the “WriteMultipleRegisters (function 0x16)” MODBUS command to the unit.
A copy of these instructions is included with the SeaI/O-463 module and can also be downloaded from the SeaI/O-463 product page on the Sealevel website. Do not perform these instructions with the power connected. Be sure to follow proper ESD procedures by grounding yourself and the SeaI/O module.
Remove the terminal block from the left side and then remove the two black screws from each side of the module as shown in the image. On the front right side of the module, wedge a slotted screwdriver between the top and bottom halves as shown. Pry upwards – a pem in the top half must clear the metal lip in the bottom half of the enclosure. Remove the two screws from the metal strain relief, as shown. Remove the three screws from the bottom of the module and remove the front plate.
Replace the metal strain relief. Start both screws and tighten only until snug. Do not over-tighten. Replace the top half by starting it on the left side over the connectors and then snapping the right side down into place. Be careful not to pinch fingers. Replace both screws on each side and then replace the terminal block on the left side. Continue with the installation of the SeaI/O-463 module.
The SeaI/O-470 module ships factory configured with the D/A outputs set for 0-10V and current loop mode on the A/D inputs disabled. If you need to enable current loop mode or set the D/A outputs to 0-5V, you will need to open the enclosure and access the jumpers (shown on the next page). Do not perform these instructions with the power connected. Be sure to follow proper ESD procedures by grounding yourself and the SeaI/O module.
This detail image of the right side of the SeaI/O-470 circuit board shows the locations of the user configurable jumpers and dipswitches. Refer to the following pages for instructions on properly configuring the jumpers and switches. The colored boxes are shown here for clarity and are not visible on the actual circuit board. ©Sealevel Systems, Inc.
The (E1) and (E2) jumpers (shown in the orange boxes on the previous page) configure the D/A outputs for 0-5V or 0-10V. Both channels can be configured independently. The D/A outputs do not support negative voltages. You must also set the correct output voltage in your application or MaxSSD. Refer to the SeaMAX Application Suite section of this manual for help configuring software to work with the SeaI/O-470.
All SeaI/O modules include two RS-485 pass-through connectors on the left side of the unit that are internally connected to the same pins on the screw terminals. This offers two convenient options for adding additional expansion modules. For connecting several SeaI/O modules together in a “stack”, all N-series expansion modules ship with an expansion and strap kit (Part# KT122) that includes four metal straps, four #4-40 screws, and a 5” RJ45 RS-485 interconnect cable (Part# CA239).
Optically isolated inputs are arranged such that each group of four shares a single common. The four I/O points and shared common are connected via a five-position removable screw terminal. Input voltage range is 5-30VDC. Like the inputs, each group of four Reed relays also shares a single common and connects via a five-position removable screw terminal. Form C Relay outputs are arranged such that each group of two relays shares a common.
The SeaI/O-462 and SeaI/O-463 use 74ABT245 octal bi-directional transceivers to provide TTL input/output capabilities and can sink 64mA and source 32mA. Each bit is pulled to +5V through a 10K ohm pull-up resistor to insure each bit is at a known state when not driven. The maximum output power is +5V @ 1A (5W). The SeaI/O-462‟s 96 digital I/O channels are brought out to two DB-78 Female connectors on the front of the enclosure (pinout shown below).

For easy connection to industry-standard solid-state relay racks, Sealevel manufactures a 6‟ cable, Part# CA237, that terminates the DB-78 to two industry standard 50-pin header connectors. Two cables and a SeaI/O unit can be order together as a kit using Part# 462x-KT. The pinout for the two 50-pin headers is shown below. ©Sealevel Systems, Inc.
The SeaI/O-463‟s 96 digital I/O channels are accessed via four industry-standard 50-pin header connectors. Each header provides 24 bits of digital I/O divided into three eight-bit ports. Each port may be individually configured via software command as an input or an output. You will need to open the SeaI/O-463‟s enclosure to access the four header connectors: P2, P3, P4, and P5. The connector designators are silk-screened onto the PCB for easy identification.
The SeaI/O-470 supports single-ended, differential, and current loop A/D inputs. Single-ended and differential modes can be configured in software. Current loop mode requires configuring dipswitches inside the enclosure. Refer to the Hardware Configuration section of this manual for instructions on configuring the current loop dipswitches. The SeaI/O-470 can be configured for up to sixteen 12-bit single-ended A/D inputs. Each input is referenced to a common ground.
The SeaI/O-470‟s A/D channels can also be configured to provide up to eight 12-bit current loop inputs. Each input has two terminals – one positive and one negative. The input current range is 0-20mA for interfacing commonly used 4-20mA devices. The dipswitches inside the enclosure must be properly configured for each current loop input. The SeaI/O-470 provides two 12-bit D/A output channels, configured for 0-10V. 0-5V mode requires different jumper settings inside the enclosure.
The SeaI/O-470 modules include eight optically isolated inputs that are arranged such that each group of four inputs shares a single common. The four I/O points and shared common are connected via a five-position removable screw terminal. The SeaI/O-470 modules provide eight open-collector digital outputs. The outputs do not source any current and must be connected to an external power source, max 30VDC. The outputs act as a switch and the circuit is open until energized.
Optically isolated inputs are arranged such that each group of two shares a single common. The four I/O points and shared common are connected via a six-position removable screw terminal. Input voltage range is 5-30VDC. Like the inputs, each group of two Form C relays also shares a single common. The NC and NO contacts of each relay along with the commons are brought out via a six-position removable screw terminal. ©Sealevel Systems, Inc.
The SeaI/O-530 modules include 16 optically isolated inputs that are arranged such that each group of four inputs shares a single common. The four I/O points and shared common are connected via a five-position removable screw terminal. The SeaI/O-530 and 540 modules provide 16 or 32 open-collector outputs. The outputs do not source any current and must be connected to an external power source, max 60VDC, through the Vin pin locations. Each output acts as a switch and the circuit is open until energized.
SeaI/O S-Series (RS-232) modules have an RJ45 connector on the face of the enclosure. Each Sseries module includes a kit (Part# KT119) to convert the RJ45 RS-232 pin out to a standard DB9 RS-232 pin out. The kit ships with a DB-9F to RJ45 modular adapter (Part# DB109) with RS-232 pin out and a standard 7' CAT5 patch cable (Part# CA246). This kit allows SeaI/O S-series modules to be easily connected to a standard DB9 RS-232 serial port. For other interfacing options, the RJ45 serial pin out is shown below.
