2.4 Service Kit Connections

The TB8100 Service Kit is connected to the BSS 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 BSS. 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 BSS,

it can sometimes cause interference to RS-232 serial port commu-

nications. If this interference does occur, we recommend fitting

ferrites on the serial cable close to the control panel. This recom-

mendation only applies to communication equipment perma-

nently connected to the BSS.

Note When a reciter fitted with a TaitNet RS-232 system interface

board is used in a TB8100 BSS, the RS-232 port on the control

panel is disabled. In this situation you must connect to the

RS-232 port at the rear of the reciter. Refer to “TaitNet

RS-232” on page 24 for more details.
