PUSH-BUTTON
This button allows us to interact with the Legacy
Connect card as follows:
NOTE: Caution must be taken when manipulating
the electronics while power is on.
NOTE: The push-button is operational only when
the Legacy Connect software is running normally.
For example, if the heartbeat LED isn’t blinking,
you won’t be able to reset the card. In that case, you
may need to power-cycle the host controller.

DIP Switches
The array of DIP switches is not used.
EOL Switch
This switch must always be in EOL position.
RS-485 Connector
This connector can be used to connect additional
RS485 modules when using a controller of the TC5
family.
RS-485 LEDs (LCRS485 model only)
Two LED indicators at the bottom-right of the card
monitor the communication between the controller
(TC5 family) and its auxiliary modules.

NOTE 3:
• Use a twisted pair shielded cable at 600V and with a temperature insulation of 90C (min). The maximum
length of the cable is 3000m (10,000 ft) and the recommended wire diameter is 1.0mm (18 AWG).
• Use a lightning protection module when running the cable between buildings.
• Interconnect shield wires together.
• Do not ground the shield wire.
NOTE 2:
Consult the Comlink-2
manual (890-00063) about more
air inlet module configurations.
NOTE 1:
No additional wiring.
