Setting the MIC400 Address (in Hardware)
The MIC-BP4 Bi-phase converter card supports changing the address of the
MIC400 at the pole base through hardware.
It should be noted that the MIC-BP4 converts all Bi-phase data into RS485 data
regardless of the address setting on the DIP switches. The MIC400 will filter and
process commands that match the current address of the MIC400.
The address setting procedure is as follows:
1. Select the appropriate address (1-255) by setting up the DIP switches. (See
tables below)
2. Press the push button (SW2) adjacent to the DIP switches to set the address.
3. The status LED will flash once indicating the start of the address setting
procedure. You should then observe the MIC400 panning this confirms that
the MIC400 has been set to the new address.
4. The status LED will be illuminated for the duration of this procedure.
Troubleshooting
1. The status LED does not flash when sending commands from the control
system.
a. Check the polarity of Bi-phase signal cables connected on the MIC-BP4.
b. Ensure the power supply is switch on.
CAUTION: The shield must be connected to the
controller end only
