Hardware Flow Control

The serial daughterboards in both Local Hub and Remote Units have a series of jumpers that

allow the selection of alternative hardware flow control schemes across the CATx link (see

Figure 10). Most applications will not require hardware flow control across the link, and

therefore the flow control jumpers are set to loopback by default and should not need

adjustment.

The following diagrams show how the jumpers may be set for various flow control schemes.

Please contact Technical Support if you are unsure about serial port handshaking methods.
