Understanding the NexSens data logger ports
Ports include:
•
(5) sensor input ports
P0A - 12V switch power, shared RS-232 with port P0B, SDI-12, RS485
P0B - 12V switch power, shared RS-232 with port P0A, SDI-12, RS485
P1A - 12V switch power, shared RS-232 with port P1B, SDI-12, RS485
P1B - 12V switch power, shared RS-232 with port P1A, SDI-12, RS485
P2 - 12V switch power, unique RS-232 port, SDI-12, RS485
•
(1) Solar charging port
•
(1) Gortex vent for relief of battery outgassing pressure. In heavy wave conditions this
vent can be plumbed with tubing to the top of the tower.
•
Antenna port
Note:
Sharing RS-232 ports means that only one non-addressable device can be
connected at a time. RS-485 and SDI-12 ports are shared throughout the bus.
Note:
To connect analog sensors (i.e. 4-20mA, 0-2.5V) use the
