TROUBLESHOOTING

SELF TEST

The BIC-II is capable of performing two levels of automatic self diagnostic tests upon initial power up; Normal,

and Test. The on board LED indicators will illuminate in a specific sequence during these tests.

Should the LED’s not illuminate once the BIC-II, board B, power switch SW1 is flipped ON, check the

following :

› power has been supplied to board B, TB3-2/3

› the power selection jumper J2 is in the appropriate position

› the power fuse is the proper rating and in intact

Should an internal fault occur during one of these tests, LED 1-8 will flash red simultaneously three times and

then one LED will remain red, indicating the following :

LED1 UART failure

LED2 EPROM failure

LED3 RAM failure

LED4 EEPROM failure

LED5 Configuration Error

Return the BIC-II to Milltronics or your distributor for repair.

A self test will also be performed if the BIC-II receives a system test request message from the host computer

during normal operation. The results of this test will be returned to the computer, refer to PROTOCOL / BIC-II

Commands.

NORMAL

The BIC-II performs a series of microprocessor and communication circuitry tests.

Set the BIC-II board A, switch SW1 contact 8 to the NRM position. Flip the BIC-II, board B, POWER switch to

ON. LED1-8 all illuminate orange simultaneously. As the 8 communication ports are activated, the respective

LED is turned OFF, starting with the "HOST" (LED1), then "MBUS" (LED2), and followed by each of the 6

product ports (LED3-8).

After a successful test the BIC-II will automatically commence normal operation.
