External RS485 Connection to GP-MC logger: |
|
|
The Remote Probe Controller is fitted with a 4 pin Switchcraft
socket for connection into a GP-MC RS485 network. In addition to the RS485 communication,
the socket also provide power for the unit. |
|
Three Analogue Channels: |
|
|
The three analog channels have identical characteristics. Each channel can operate in two modes, Absolute and Ratiometric. The mode of operation is determined by the probe type selected for that
channel. The probe type is selected using the Channel and
Probe Setup Tab of the Logger Control Screen in the Omnilog Software. Using this software,
a different Probe can be selected for each Channel. Temperature
(Thermister) , Pressure and Humidity probes are typically Ratiometric. Voltage and current inputs are Absolute. |
