The pin allocations for the RJ45 Ethernet connector are given in the
following table.
2.5 Service Kit Connections
The TB8100 Service Kit is connected to the base station via the RS-232
serial port on the control panel. This port is a 9-way female D-range
connector. Use a straight through cable, as supplied with the Service Kit,
to connect your programming computer to the base station. The pin
allocations for the serial port are given in the following table. Note that pins
1, 4 & 6 and pins 7 & 8 are linked. This port is also used for remote
connection to the Service Kit or Alarm Center software via a modem or
radio modem.
Note If high-power HF equipment is located close to the TB8100 base
station, it can sometimes cause interference to RS-232 serial port
communications. If this interference does occur, we recommend
fitting ferrites on the serial cable close to the control panel. This
recommendation only applies to communication equipment per-
manently connected to the base station.
