RX10 Ten-Zone Receiver Decoder
Overview
The RX10 is a POCSAG receiver decoder equipped with 10 individually switchable relays, a Common relay
and an RS232 serial port.
A full function PC programming utility allows each relay to be configured to respond to a transmitted RIC
(receiver identity code) or a range of RIC’s. This will allow the user to independently energize (Close), de-
energize (Open) or alternate (Toggle) the state of each relay by transmitting specified RIC’s or ranges of
RIC’s*.
Additionally, the user can Close or Toggle each relay for a defined time period (1-255 seconds). Sending
repeat transmissions during the set time period will reset the timer, which allows a relay to be used as an
“in service” monitor. Example: as long as the unit keeps seeing the repeat transmissions within the set
time period, the relay will remain latched. If a transmission fails to be received within the set window, the
relay will drop out at the end of the set time period.
All relays have N/O, N/C and Common connections available on screw terminal blocks located on the main
circuit board (see diagram 1). The maximum contact rating of each relay is 0.5A @ 125V AC, 1A @ 60V DC.
A Common relay will latch when any of the 10-zone relays is triggered. This can also be programmed to
activate an internal sounder.
The unit can be reset by using either the key operated switch on the front of the RX10, or by transmitting a
programmed RIC. This will de-energize all relays and return the system to its initial power up state.
An RS232 serial port provides a data logging or repeater function. This can be programmed to send
transmitted messages to the serial port when either two individual RICs are specified, or when a range of
RICs is specified. Additionally, the unit can be configured to send Scope protocol for onward transmission
(using a Scope transmitter on a different frequency).
Front panel LEDs indicate when each relay is energized and a flashing LED advises when transmitted
data is received. A cool blue power LED completes the picture.
Power input requirement is 12V DC @ 0.7A, via the blue latching connector provided.
*Each RIC must be a 7-digit number in the range 0000008-2097151, excluding ranges
2007664-2007671 and 2045056-2045063.
