TB8100 Installation and Operation Manual Connection 105

Note The microphone input feeds simultaneously to both base station 1

and base station 2. However, the PTT can only be used on the

currently selected base station. The RS-232 connection is only to

the reciter on the currently selected base station. You should dis-

connect the Service Kit before switching base stations.

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 118 for more details.

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.
