Hardware
Flow Control
The COM Port uses hardware flow control to manage the
data throughput. Ensure that the cables and network
hardware you use have the proper hardware flow control
connections to prevent lost data.
Note: To use the 2300EU for simultaneous data access,
you must make sure that the COM port settings for your
Remote Module, remote PC, Switch Module, and data
communications server all match.
