PRX4SERL Four-Zone Receiver Decoder
Fit the required switch cables to the appropriate relays. These are labeled Zone 1 to Zone 4. Terminals are
available on each relay for Normally Open, Normally closed and Common.
Finally, connect the blue latching power connector to a 12V dc @ 0.5A power supply, observing the correct
polarity, as shown in diagram 1.
Where the unit has been ordered as a PRX4SERL with the serial port enabled, the 9 way D connector is
used to connect the unit to a serial printer or PC for data logging purposes, or to a Scope transmitter for a
repeater application. The serial port configuration is 9600 baud, N, 8, 1. A standard serial cable (null
modem) is required.
Operation
PRX4SERL
This unit utilizes firmware which facilitates the following features:
1) There are four configurable capcode ranges which can be specified for activating each relay. Each range
can be specified as either numeric or alphanumeric. Sending a capcode within the set range will latch the
relevant relay and light the corresponding onboard LED.
2) An on-board sounder can be configured to beep every time data is received.
3) Serial output is available on the 9 way D-Connector. This can be specified to output text only (for
connection to a printer or PC), or Scope protocol for onward connection to another Scope transmitter (for
use as a repeater).
4) The receiver will decode POCSAG transmissions sent at 512 baud or 1200 baud (not both). This must
match the transmitter over the air baud rate.
All these features are factory set, so they need to be specified at the time of order placement.
