g. Check software compatibility between the PMF and the MicroTech controller.
Using the prepared address schedule, verify that the IDENT from the controller just
connected is listed on the schedule as being compatible with the PMF version being used in
the gateway.
If the controller’s IDENT revision is earlier than those listed in the schedule, it may be
necessary to download updated code to the MicroTech controller.
If the controller’s IDENT revision is later than those listed in the schedule, you should
obtain the latest version of the BDIP for that MicroTech application. It may be necessary to
download an updated PMF to the BACdrop gateway.
9. Go to the next controller and repeat step 8. Do this for each controller being connected to the
network.
Communications must be established between the BACdrop gateway and every
controller on its network before the network is turned over to the BAS personnel.
10. Disconnect the commissioning PC from the BACdrop gateway. The BAS can now be connected
to the “Ethernet” port.
