Operation
The PSU-22 can be used either:
1. As a stand alone unit. For example, in a monitor stack with dynamic displays or static displays
not requiring serial tally information, but where the silence detection data from Audio
Monitoring Units needs to be passed to an alarm monitoring system such as the TSL AMS-1,
or, more usually.
2. As a single or one of several local power supplies of a larger system where the displays are
controlled by a TallyMan Controller, TM1.
The input RJ45 serial port on the rear of the PSU-22 is fed from any TM1 Display Port which could be
located at some distance away (up to 200m) from the monitor stack.
