Power Options Base Module Power Connection Base modules are powered from a 9-30VDC source using either the DC jack or screw terminals on the side of the unit. Sealevel offers several power supply choices to make connection easy (see the Accessories chapter at the end of this document). SeaI/O Expansion Power Connection Each SeaI/O product, including the expansion modules, contains an onboard switching regulator power supply rated for 9-30VDC.
Sample Power Calculation A typical application for SeaI/O products would use one Base module and several Nseries units in a local expansion configuration. In this arrangement, with power applied to the Base module through either the DC jack or screw terminal connector and passed-through to the expansion units, attention should be given to ensure the input power to the Base module is adequate. Example: Base Unit: Expansion 1: Expansion 2: SeaI/O-430U SeaI/O-410N SeaI/O-440N Power (W) 0.7 1.4 2.5 4.
SeaMAX Application Suite SeaMAX Overview The SeaMAX Suite is a collection of software libraries, and configuration and diagnostic utilities that facilitates rapid application development.
Communicating Via Modbus Sealevel SeaI/O and SeaDAC modules are designed to integrate seamlessly into existing Modbus networks. The supported command set will vary depending on the SeaI/O model number used. Specialized diagnostic commands and other RTU specific codes are not supported. An overview of the Modbus specification for both RTU and TCP connections is covered in detail in the interactive documentation located on the Sealevel website at: http://www.sealevel.
SeaMAX Software Installation Proceed with installing the SeaMAX Software Suite using the software CD 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. Windows 2000/XP/Vista™ Operating Systems NOTE: Important! Do not connect the I/O module to the host until the software is installed. 1. Start Windows. 2. Insert the Sealevel Software CD in to your CD drive. 3.
MaxSSD Configuration & Diagnostics Utility 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, and Vista. Host PC Configuration Tab The first time you run the MaxSSD utility (Start Æ All Programs Æ Sealevel SeaMAX Æ MaxSSD) it will default to the “Host PC Configuration” tab.
Host PC Configuration Tab (continued) To communicate with a SeaDAC Lite module, select “SeaDAC Lite” from the “COM Port” dropdown box. MAXSSD will search for any SeaDAC Lite modules connected to a USB port and display them in a frame (as shown below). A new “Digital I/O” tab will appear. If more than one SeaDAC Lite module is connected, select the one you want to test from the list and click the “Digital I/O tab”. You can use this new tab to test the functionality of inputs and relay outputs.
SeaI/O Configuration Tab Once the host computer is configured correctly, the “SeaI/O Configuration” tab becomes available. This tab only appears for SeaI/O and SeaDAC modules and will not appear when using SeaDAC Lite modules. Before communicating with a SeaI/O or SeaDAC 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.
SeaI/O Configuration Tab (continued) After the Get command is executed, the “Module Description” frame will display the model type, description, interface, and I/O type. In the example shown, the module found at slave ID 247 is a SeaI/O-410 module with an Ethernet (Modbus TCP) 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.
SeaI/O Configuration Tab (continued) The “Broadcast to Multiple Modules” checkbox, along with the “Set Settings” button can be used to change the baud rate and parity on multiple SeaI/O modules at once. This function only works with SeaI/O modules connected together via the passthrough connectors. This function is disabled with SeaDAC and SeaDAC Lite modules since these devices do not have pass-through connectors.
Digital I/O Tab 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 or SeaDAC modules (excluding SeaDAC Lite), 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.
Digital I/O Tab (continued) When displaying SeaDAC Lite modules, the “Digital IO” tab displays inputs and outputs in groupings (or banks) of four. Therefore, a SeaDAC Lite module with four inputs and four outputs would show only one bank of inputs and one bank of outputs. When banks of inputs are displayed, the status LEDs update on each of the banks automatically. This allows you to actively monitor external signals.
Programmable I/O Tab The “Programmable IO” tab of MaxSSD is displayed when using Sealevel I/O devices featuring programmable inputs or outputs. This tab allows for bank configuration, input/output configuration, as well as bit-level presets. Each bank of programmable I/O can be set as either an 8-bit group of inputs or outputs.
A/D Inputs Tab 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.
D/A Outputs Tab 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 and SeaDAC 8227 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.
A/D & D/A Diagnostics 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.
Troubleshooting SeaMAX 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 first, 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.
Troubleshooting Ethernet & Wireless SeaI/O Modules 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.
Hardware Configuration Setting Device Address (Slave ID) 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.
Setting Termination & Pull-Up/Pull-Down Resistors 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.
Configuring the “Base” SeaI/O Module 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.
Configuring N-Series 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 (item# CA239) to simplify daisy-chaining SeaI/O modules together.
Configuring a Wireless (W-Series) Module NOTE: 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.
Configuring a Wireless Module (Continued) 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. NOTE: To configure a wireless SeaI/O module, you must be using a laptop or desktop computer with a wireless 802.11b/g compatible adapter.

Configuring a Wireless Module (Continued) Start the Ethernet Config utility (Start Æ All Programs Æ Sealevel SeaMAX Æ 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.
Configuring a Wireless Module (Continued) 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 Æ Settings Æ Network Connections). Right-click on your network adapter and then select Properties from the menu. This opens the Wireless Network Connection Properties window.
Configuring a Wireless Module (Continued) NOTE: Before you change any settings in the following window, make a note of your original settings. You will need to revert back to your original wireless adapter settings once you have successfully configured the wireless SeaI/O module to work with your network. In the Internet Protocol (TCP/IP) Properties window, click the radio button for ‘Use the following IP Address’.
Configuring a Wireless Module (Continued) To confirm that the IP Address for your wireless adapter was changed successfully, reopen Ethernet Config (Start Æ All Programs Æ Sealevel SeaMAX Æ 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.
Configuring a Wireless Module (Continued) Now that you can communicate with the wireless SeaI/O module, the Wireless Configuration settings window will open, as shown. 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 20 seconds to appear on the network using your new settings.

Wiring Options SeaI/O Pass-Through Connector 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.
I/O Wiring – SeaI/O-410, 420, 430, 440, and 450 Modules 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 fiveposition removable screw terminal. Form C Relay outputs are arranged such that each group of two relays shares a common.
I/O Wiring – SeaI/O-462 and 463 Modules 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).
SeaI/O-462 Optional Cable (Item# CA237) Pinout For easy connection to industry-standard solid-state relay racks, Sealevel manufactures a 6’ cable, Item# 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 Item# 462x-KT. The pinout for the two 50-pin headers is shown below. © Sealevel Systems, Inc.
SeaI/O-463 50-Pin Header Connectors The SeaI/O-463’s 96 digital I/O channels are accessed via four industry-standard 50pin 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.
I/O Wiring – SeaI/O-470 Modules A/D Wiring Connections 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.
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. D/A Wiring Connections 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.
Digital I/O Wiring Connections 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.
I/O Wiring – SeaI/O-520 Modules 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.
Connector Pin Outs SeaI/O (RS-232) S-Series Modules SeaI/O S-Series (RS-232) modules have an RJ45 connector on the face of the enclosure.
