Reduced Wiring Feature
Terminals J1-5 and J1-6 can be used to reduce wiring to make installation easier.
Internally, J1-5 is connected to J1-3, and J1-6 is connected to J1-4. This can reduce
wiring in two ways. See Figures 3 and 4.

Initial PC Setup/ Bluetooth Modem Discovery
The following procedure must be done at least once for the PC to “Discover” the HM-
BT-VIN.
1.
Apply power to the HM-BT-VIN. It does not need to be connected to the HART
network.
2.
Run the Bluetooth driver software that came with your PC or Bluetooth adapter
(ie Linksys). There is typically a Bluetooth icon on the system tray that can be
double clicked.
