8-Pin Sensor Port Signal Information

Note: All splitter extensions contain the same pinout and signal configuration; however, only one 232 sensor can be connected to each splitter/port. The arrow on the 2-way splitter and the end port on the 4-way splitter indicate which port the 232 sensor may be connected.

MCIL-8-MP Sensor Port Pin# Signal
1 RS232 Tx*
3 RS232 Rx*
4 +5V
5 +12V
6 SDI-12
7 RS-485B
8 RS-485A

*RS-232 transmit/receive is labeled from the data logger’s perspective (should be wired to the sensor’s receive/transmit, respectively).
