CONNECTING THE DECODER TO AN ETHERNET CONNECTOR
The decoder is designed to be used with either 10Base-T (10 Mbps) or 100Base-TX (100 Mbps) also
known as Fast Ethernet, twisted pair Ethernet cabling systems.
systems, category 3, 4, or 5 UTP cable as well as EIA/TIA – 568 100Ω STP cable may be used.
When connecting for 100Base-TX systems, category 5 UTP cable is required. The cable must be
"straight through" with a RJ-45 connector at each end. Make the network connection by plugging one
end of the cable into the RJ-45 receptacle of the decoder and the other end into a port of the
supporting hub. If you are connecting the decoder directly to a PC, then you will have to use a
crossover cable.

A 9 pin female 'D' connector for connection to the RS-232 serial
communications.
This port is configured for a 'straight through' RS-232
connection to a PC COM port and can be used for uploading firmware, and
updating/changing the units IP address. Table 2-1 shows the pin out of the
serial port in its default RS-232 DCE configuration.
