Model Info

The DSX-SPST (Serial Port Switch Trigger) board is the power distribution and Backup Comm Server monitoring board. It receives +15VDC (Class II Power Limited) from the DSX-1040PDM board and distributes it to the 2PC boards through 4 - 12VDC, 1A fused outputs. The SPST board has an RS-232 port that connects to an extra port on the Backup Comm Server. This is the port which sends the “activate” command. The SPST also has 4 relay outputs that are used to “trigger” the 2PC boards when the “activate” command is received.
