Bias/EQ – The value in this field is a guide to
the strength of equalisation that is being
applied to the input signal for longer cable
runs. The lower the value, the less equalisation
is being employed. It is intended as a guide for
troubleshooting the system. It should be noted
that when an equalisation of 100% is shown, it
doesn’t necessarily mean that the maximum
input cable length has been reached. As soon
as CRC errors are being reported then the
input cable length should be decreased until an
error free signal can be received.
