4.4. Connecting the Network Cable
The CMS Network Port is an RJ45, 10BaseT Ethernet Jack, for
connection to a TCP/IP network. Connect your 10BaseT or
100BaseT network interface to the CMS-32 Network Port.
The CMS features a default IP Address (192.168.168.168.)
Providing that you are communicating with the unit from a node
on the same subnet, this allows you to initially contact the CMS
without first accessing the CMS command mode to define an IP
Note however, that when installing the CMS in a working
network environment, it is strongly recommended to assign the
IP Address, Gateway Address, and Subnet Mask as described in
Note: The CMS features a 10BaseT Interface.
When connecting the CMS to a 100BaseT interface,
note that most router switches will autosense to
determine if the device is 100BaseT or 10BaseT, and
then configure the network interface accordingly. If
your router switch does not autosense, the network
interface port must be manually set to 10BaseT.
4.5. Connecting Devices to the CMS
1. Determine which CMS port will be used for connection to
the new device (e.g. Port 3).
2. Use an appropriate DB9 cable to connect the RS232 serial
port on the device to a DB9 port on the CMS.
a) External Modems and other DCE Devices: Use a
standard serial modem cable.
b) PCs and other DTE Devices: Use a standard null
3. Access the CMS command mode and then select
communication parameters for each CMS port as described
in Section 5.5.
