1.3.2
External Connector
The VR2C uses a submersible connector (SubConn PN: MCBH8M) to allow for a
cabled interface to a customer PC, a third-party data logger, a modem, or other
supported host device.
The VR2C external connector supports both RS232 and RS485. By using an RS232 or
RS485 cable, communication with the VR2C can occur through either serial interface,
although not both at the same time. Specifications for the cable are found in section
4.2. RS232 communication can only be used for cables that are less than 15.2 m
(50 feet).
The VR2C connector pin-out, as shown from the external view, is listed below.
