B.1 Cables for DCT1800 and DCT1900
Figure 84. Connection for messaging in DCT1800 and DCT1900 systems.
A cable with RS232 and D-SUB (9-pin female) connectors is required to be able to transmit
messages to handsets and to receive messages, data and alarms from the handsets. The
cable should be connected to the COM1 port on Unite CM and to the Printer (PR) port on the
Radio Exchange. To be able to configure DCT1800/DCT1900 remotely via a Unite CM, this
type of cable should also be connected between the COM2 port on Unite CM and the PC port
on the Radio Exchange.
