Transducer RX
The Transducer RX is connected to the DRX through seven receive cables. The receive
cables must be connected in the colour order shown on the connector.
See “Appendix A.1 Transducer RX” on page 76
for connection specification.

CAUTION: The 7 receiver cables MUST be connected in the colour order
indicated on the DRX. Failure to do this will result in faulty operation of the
WASSP system.
CAUTION: The cable MUST be fitted with the supplied cable restrainer to
prevent stress on the RJ45 Receive connector block.

NOTE: Actual product may differ from images depending on model.
See “8 Outline Drawings” on page 66.
Transducer Tx
The Transducer Tx cable applies transmit signal to the transducer.
See
“Appendix A.3 Transducer Tx” on page 78 for connection specification.

RS-232 IN/OUT
Connector
RS232
RS-232 is a serial connection for sensors/processors that natively output RS-232. For
NMEA 0183 talkers it will depend on the instrument as to whether it will be RS-232
compliant or require a converter. RS-232 supports power out at same voltage as DRX
power supply.
See “Appendix B - Supported Sensors and Sentences” on page 87.
RS-232 can be configured using the
DRX SETUP WEBPAGES
.
Step 2: Sensor Configuration” on page 36.
See “Appendix A.4 RS-232” on page 79
for connection specification.
RS-422 IN/OUT
Connector
RS422-A and RS422-B
RS-422 is a serial connection for sensors natively outputting RS-422 or by using RS-232 to
RS-422 converter. For NMEA 0183 talkers it will depend on the instrument as to whether
it will be RS-422 compliant or require a converter.
The RS-422 Connector also supports PPS IN:
»
RS-422-A supports power out at same voltage as DRX power supply
»
RS-422-B allows data forwarding and power out at same voltage as DRX power
supply
See “Appendix B - Supported Sensors and Sentences” on page 87.
RS-422 can be configured using the
DRX SETUP WEBPAGES
.

See “Appendix A.5 RS-422-A” on page 80
and
“Appendix A.6 RS-422-B” on page 81
for connection specifications.
NMEA 0183
Connector
0183
NMEA 0183 is a serial connection for sensors natively outputting NMEA 0183 (single
talker, multi listener). As well as an NMEA input, this connector also features an NMEA
output.
The 0183 Connector also supports PPS IN.
See “Appendix B - Supported Sensors and Sentences” on page 87.
NMEA 0183 can be configured using key
DRX SETUP WEBPAGES
.
Commissioning Step 2: Sensor Configuration” on page 36.
See “Appendix A.7 NMEA 0183” on page 82
for connection specification.
Remote Power
Connector
AUX
A local supplied latching switch can be connected to pins eight (Remote PWR On) and
nine (Remote PWR On GND) of connector AUX. When the switched is closed the DRX will
power on. When the switch is open (circuit open) then the DRX will power off.
See “Appendix A.8 Remote Power” on page 83 f
or connection specification.
