4. Installation
Installation of the TSAM consists of:
• Pre-setting jumper options
• Mounting the unit in a cabinet
• Routing the 25 pair control and audio cable(s) to the cross-connect panel
• Routing the power cable
• Programming the options
• Setting the system transmit and receive audio levels.
4.1 Power Supply Requirements
The TSAM requires either 24V DC or 20V AC at 1 amp maximum for proper operation. A 2-conductor
power connector and cord are supplied. Although the TSAM is polarity insensitive, observe proper color
coding conventions when connecting the TSAM to a DC supply.
4.2 Expansion TSAMs for more than 8 Transmitters
Multiple TSAMs can be linked together to control more than 8 transmitters or receivers on one channel.
As many as 8 TSAMs can be tied together. This allows control of up to 64 transmitters. If you have
expansion units, you will have to change some jumpers in the units before you mount them (unless the
units are marked as expansion units from the factory).
4.2.1 Expansion Cables
When multiple TSAMs are used together, they are linked through the expansion bus. The expansion bus is
made up of the necessary audio and control busses to allow TSAMs to share transmitter control hardware.
The master and slave units are connected via a daisy-chain ribbon cable that connects to P103 on all
TSAMs on the channel. Cables are available for systems with 2-8 TSAM units. See Table 1 TSAM
Accessories for part numbers.
When installing the expansion cables, install the supplied cable grounding clamps.
