Reset/Status
A 9-way D-type female sub-miniature connector
provides an alarm relay interface, which can be used to
remotely signal equipment or input signal failure. The
fail relay is driven by an equipment failure and the
alarm relay is driven by an equipment alarm
(see Chapter 8, Preventive Maintenance and
Fault-finding).

Ethernet 1, Ethernet 2
The Ethernet ports are used to provide network connections
for the Modulator. Both Ethernet ports may be connected
simultaneously for network redundancy purposes. The
input to ETHERNET 2 is ignored if an input to ETHERNET 1
is detected.
