Test Procedures
If you can control the unit from its keypad, but you are not able to communicate with unit via the
network:
• Check the network wiring
• Check communications
• Use the standard TCP/IP suite of protocols to check your connectivity with other devices.
For example, type “ping <IP address of the MicroTech II BACnet Communications
Module>.” If you get a response from that IP address, you are connected to the BACnet
Communication Module.
If the BACnet Communication Module still does not respond, call the McQuay Controls Customer
Support group at 866-4MCQUAY (866-462-7829).
