Description
This amber (or red on early boards) LED turns
on to indicate that the controller has power
applied.
This red LED indicates CPU integrity by blinking
every second.
A green LED flashes to indicate when the device
is transmitting out the associated port, and a red
LED flashes to indicate when the device is
receiving data through the port.
DEBOUNCE
Debounce circuitry, which may be necessary for dry/mechanical
contacts, may be enabled or disabled per pulsed input with this jumper
setting – but is limited to pulses less than 200 Hz.
Enabled  With the jumper in place, debounce circuitry is connected
in circuit. Do not use this setting with open collector pulse
inputs.
Disabled  Without the jumper, debounce circuitry is
circuit.
NETWORK CONNECTION (No Jumper)
Not applicable – there is no jumper. This module is fixed so that it may
only be connected directly on a BACnet RS-485 MS/TP network. Do
not connect this module to a LINKnet network.
