Overview This section defines what hardware and software platforms are supported in this guide. It also provides information about finding: • Hardware installation documentation, if you have not installed the hardware • Latest released NS-Link™ drivers In addition, it provides an overview of NS-Link and it’s requirements. Install the NS-Link driver if you want to use the DeviceMaster serial ports as native COM ports.
Locating Hardware Installation Documentation Locating Hardware Installation Documentation Use the hardware installation documentation to install the hardware before installing NS-Link. The hardware installation documentation is available on the Comtrol CD that ships with your product or you can download the current version from the ftp site using the following links. • DeviceMaster Serial Hub User Guide or http://support.comtrol.com/ download.
NS-Link Overview NS-Link Overview The following subsections discuss NS-Link features and topics that you may want to review before installation. Connectivity Requirements An Ethernet connection, either to an Ethernet hub or to a network interface card (NIC) in the host system. See the hardware installation documentation (Locating Hardware Installation Documentation on Page 6) for information regarding hardware installation.
IP or MAC Addressing Issues IP or MAC Addressing Issues This is an overview of IP and MAC addressing issues that may affect how you configure the Comtrol device with a brief discussion of advantages of each method. The IP addressing scheme has the following advantages: • Uses an industry standard protocol. • Allows you to configure systems to use ports on the Comtrol device that are outside of the host system’s Ethernet segment.
Device Preparation for NS-Link Device Preparation for NS-Link Use the appropriate table to verify that your hardware was installed properly and is ready for NS-Link installation. See the hardware installation documentation (Page 6) if you need to install the hardware.
DeviceMaster RTS LEDs DeviceMaster RTS LEDs Use this table to verify that your DeviceMaster RTS is ready for NS-Link installation. Model How to tell if the DeviceMaster RTS is working properly: • DeviceMaster RTS 1-Port • The Status LED on the front of the unit is lit, which indicates that it has power and has completed the boot cycle. Note: The Status LED flashes while booting and it takes approximately 15 seconds for the bootloader to complete the cycle.
DeviceMaster PRO LEDs DeviceMaster PRO LEDs Use this table to verify that your DeviceMaster PRO is ready for NS-Link installation. Model How to tell if the DeviceMaster PRO is working properly: • DeviceMaster PRO 8 Note: The PWR LED flashes while booting and it takes approximately 15 seconds for the bootloader to complete the cycle. • The red LNK/ACT LED is lit, which indicates a working Ethernet connection.

For example, if renumbering a four port device from COM3 through COM6 to COM4 through COM7, and you do not select this option, a warning message for COM4, COM5, and COM6 displays. j. If you need to configure RTS (Request to Send) options, select the RTS Toggle tab. k. Configure the port and select Ok after making the appropriate selections.
Comtrol Tools This section discusses the following utilities that are installed with most Comtrol drivers for Microsoft operating systems: • Test Terminal program (wcom32.exe), which can be used to troubleshoot communications on a port-by-port basis (Using Test Terminal on Page 69). • Port Monitor program (portmon.exe), which checks for errors, modem control, and status signals (Using Port Monitor on Page 71). In addition, it provides you with raw byte input and output counts.
Testing a Comtrol Device If the COM port does not exist or if it is currently being used by another program, a Create File Error message displays. If the COM port is available, a terminal window pops up: Note: Notice the button in the terminal window. If this option is activated, it is green and uppercase ( ), the COM port internal loopback feature is activated, and the data is returned by the COM port hardware.
Testing a Comtrol Device (RS-485) Testing a Comtrol Device (RS-485) Perform the following procedure to determine if a port or ports are functioning properly. 1. Connect a straight-through cable from Port 1 to Port 2. Note: See hardware installation documentation for the device if you need to build a cable. If testing ports other than Ports 1 and 2, simply connect the cable between any two ports. 2. Open a session for each port. 3.
Starting Port Monitor Starting Port Monitor To run Port Monitor, select Port Monitor from the NS-Link Comtrol program group. The Port Monitor window displays: Note: To change the appearance of the screen, see the following discussion. Once the monitor window displays, Port Monitor is active and collecting data. If any cumulative data has been saved from previous sessions, it is automatically brought in and used.
Column Setup Column Setup Report Configuration When you select Add or Properties from the column pop-up menu, the Column Setup window displays: • Use the Input droplist to select the variable displayed in the column. • Use the Type droplist to select the way in which the value displays: either as an integer, as an on/off state, as an integer with a kilo, mega, or giga suffix, or as an hh:mm:ss time stamp. This defaults to the appropriate type for the selected Input variable.
Port Monitor Files executed after the daily reports have been generated. The Update Time option allows you to set the rate at which the port information is obtained and the calculations performed. There is a trade-off between Port Monitor efficiency and response time. If you are using Port Monitor to view the port activity on the screen, you may want to set the update time to 1 or 2 seconds, so that the screen is updated frequently.
Port Monitor Variables Port Monitor Variables The following table lists Port Monitor variables. Variable Comtrol Tools Description Open Open status, on if open, off if closed. Cts Input CTS pin status. Dsr Input DSR pin status. Cd Input CD (carrier detect) pin status. Rts Output RTS pin status. Dtr Output DTR pin status. TxTotal Total bytes transmitted. RxTotal Total bytes received. TxCPSInst Instantaneous average of transmit characters per second.
