Issue
Failing communications from a MicroNet View front end.
Environment
MicroNet View communicating to a MicroNet ARCnet or NCP LAN.
Cause
MicroNet Mi bit switches not set correctly.
Resolution
Cold Starting a MicroNet Mi
Caution: The cold start procedure clears all configuration data from the non-volatile EEPROM of the device and reloads default settings. A cold start is performed using bit switch S1, as shown in the following diagram.
To perform a cold start:
- Energise the device and verify that the RUN LED flashes at about once per second.
- Unplug any connections to 9 pin plug 3 and 9 pin plug 4.
-
Set all switches to the off position.
-
Place bit switch 8 in ON position and then return to OFF position. You will not see anything change.
-
Place only switch 1 in the ON position. The remaining switches must be in the OFF position.
-
Place bit switch 8 in ON position and then return to OFF position. You should see the RUN, WINK and MODEM LEDs remain lit for about 1.5 seconds, then the RUN LED should flash at about once per second.
-
Place switches 1 to 4 to ON for compatibility with NCP/ARCNET I/O- Server (MicroNet View versions 1.0 and later).
Note: This is different from the cold-start procedure for a controller, which requires you simply to toggle switch 8. See data sheet DS10217A for more information.
