NexSens MCIL-8-MP Port Pinout
NexSens X2-SDLMC, X2-CBMC, and X3-SUB data loggers incorporate MCIL-8-MP plugs for connection of sensor cables with MCIL-8-FS plug connectors. The pinout for the sensor ports is as follows:
Figure 1: MCIL-8-MP pinout
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 indicates on which port the 232 sensor may be connected.
| MCIL-8-MP Sensor Port Pin# | Signal |
| 1 | RS232-Tx* |
| 2 | GND |
| 3 | RS232-Rx* |
| 4 | — |
| 5 | Power (12VDC) |
| 6 | SDI-12 |
| 7 | RS-485B |
| 8 | RS-485A |
*RS-232 transmit/recieve is labeled from the data logger’s perspective (should be wired to sensor’s receive/transmit, respectively).
