CMS-6R4 Series - User’s Guide
4.3. Connecting Devices to the RS232 Serial Ports
The six, serial RS232 Ports on the CMS-6R4 back panel are standard DB9 connectors, configured as DTE Ports, and are similar to a standard serial port on a PC. Note that Port 1 is designated as a System Set Up Port, and that in order to ensure that this port is always accessible by system administrators, the Supervisor Mode cannot be disabled at Port 1. For a description of the RS232 Port interface, please refer to Appendix A.
Use a DB9 cable to connect the RS232 serial port on your device to the RS232 serial port on the CMS-6R4 back panel. When connecting external modems and other DCE devices, use a standard serial modem cable. When connecting PCs and other DTE devices, use a standard null modem cable.
4.4. Connecting Control Devices to the CMS-6R4
The CMS-6R4 can be controlled and configured via local serial connection, or controlled remotely via modem or TCP/IP network connection.
4.4.1.Control via Local PC
Use the supplied null modem cable to connect your PC COM port to one of the CMS-6R4's two RS232 System Setup Ports. The System Setup Ports are male, RS232C DB9 connectors, wired in a DTE configuration. In the default state, the Setup Ports are configured for 9600 bps, no parity, 8 data bits, 1 stop bit.
4.4.2.Control via Modem
Connect your telephone line to the Phone Line port on the CMS-6R4 back panel. If necessary, configure the Modem Port as described in Section 5.5.4.
4.4.3.Connecting the Network Cable
The Network Port is an RJ45 Ethernet jack, for connection to a TCP/IP network. Connect your 10Base-T cable to the Network Port. Note that the CMS-6R4 includes a default IP address (192.168.168.168) and a default subnet mask (255.255.255.0.) When installing the CMS-6R4 in a working network environment, it is recommended to define network parameters as described in Section 5.5.2.
Note: The CMS-6R4 features a 10Base-T network interface. When connecting to a 100Base-T interface, most router switches will autosense to determine if the device is 100Base-T or 10Base-T,
and then configure the network interface accordingly. If your router switch does not autosense, the network interface port must be manually set to 10Base-T.
This completes the CMS-6R4 installation instructions. Please proceed to the next Section for instructions regarding unit configuration.
