    1. CONFIGURATION The Primax PCOM Communication Card operates in the following modes: Slave Modbus RS-232/485 Slave Modbus TCP/IP Slave DNP3 (available only in the R232/485). The RS-232/485 operates with 8 bits, 1 start and 1 stop bit. The speed of the transmission is configured on the PCOM board, and selected by switch SW2 (see table 2).

  • Page 101: Connection

    1.2 RS-232 CONNECTION The RS-232 standard allows only a single point-to-point connection. The cable needed for the RS-232 communication is a standard one with DB9 male and female connectors. The DB9 male is connected at the PCOM side and the DB9 female is connected at the customer DTE.

    1.4 ETHERNET TCP/IP CONNECTION 1.4.1 Network precautions: before you start The Primax PCOM board, provided in your kit is designed to connect to a network over Ethernet. As with any system, however, some precautions are in order before you connect. Whenever new hardware or software is added to a network, it is always advisable to create a separate test network that is isolated from your LAN.

  • Page 104: Connecting Directly To A Host System

    This configuration is the basic method of networking the PCOM board. This assumes there is a stable Ethernet network using TCP/IP for communications and that at least one DHCP server is present on the network. To set up the board for direct networking (Figure 4), connect the straight-through Ethernet cable to the board at Ethernet connector “ETHERNET”, then to the Ethernet network.

  • Page 106: Configuring The Pcom Board

    1.4.6 Configuring the PCOM board Once the PCOM board is properly connected, it needs to be configured to operate on the network or with the host system that it is connected to. As already mentioned, the board is factory-configured for DHCP operation; it should automatically acquire an IP address on DHCP-enabled networks and be available for immediate use.

    7. Select option “3” at the prompt, enter the board’s new IP address based on the configuration you are using: If the board is connected to the local host system through a crossover cable: Use your host system’s IP address, incremented by one, in the final position.
