Turning on the YHC
Use the dedicated

YHC model number, and YHC firmware version is displayed. A message is displayed indicating the YHC is
scanning for a HART device at address zero. The following scenarios are possible.
1.
If the YHC is connected to a HART device with address = 0
(and there is sufficient loop resistance), the YHC immediately
establishes HART communication with the device. A display
similar to the example at right appears. The numbered menus
and Soft Keys are then used to commission, re-configure, or
maintain the connected device.
