10 Enwatch Unit
Serial Port (RS-232)
An RS-232 compatible serial port is available for providing local communication
with the board (independent of the Ethernet network). Only RXD and TXD
lines are supported, and so a null modem cable must be used. An on-board
software monitor is provided to communicate through the serial port.
If you do not use a 9-pin female to female null modem cable, the recommended
cable connection to a computer is defined in the table below.
Transducers
The following sections show how to connect transducers to the Enwatch
