Rear Panel Information
Power
The POTS-1 requires a 24V DC power source to operate, but is capable of accepting dual 24V DC inputs for redundancy. Both power
sources may be connected concurrently, however each must be capable of supporting the full 30-Watt load of the unit (inputs are not
intended to load-share). Loss or return of either power source will not result in an interruption to normal operation as long as one of these
power sources remains functional. Monitoring of all power sources is selectable via the Vocia software.
The power connector is a four-way 5.08mm standard header with mating pluggable screw terminal block with cable restraint.
Pin Function
1 DC Power 1 24V(+)
2 DC Power 1 24V(-)
3 DC Power 2 24V(+)
4 DC Power 2 24V(-)
Device ID
The rotary ID switches on the POTS-1 give the unit a unique Device ID. The switches are in hexadecimal format. All POTS-1 units must
have a unique Device ID to function within a Vocia Paging World (i.e. it is not possible to have two POTS-1 units with the same Device
ID of hex 07). To assign a Device ID of hex 07, turn the MSB switch on 0 and leave the LSB switch to 7. To create
an ID of hex B7, turn the MSB switch to B and turn the LSB switch to 7. Device ID switches should be set using a
0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver. More information on setting IDs and the hexadecimal
numbering scheme used in Vocia can be found in the Vocia Help File. Please note: changes made to the Device ID
while connected to the network require a power cycle in order to take effect.
