TEST
The BIC-II performs more extensive circuitry tests and then awaits the operator to perform a DIP switch and
LED test.
Set the BIC-II, board A, switch SW1 contact 8 to the TST position. Flip the BIC-II, board B, POWER switch to
ON. The following LED activity, indicating a successful test, may be observed :
› LED 1-8 all flash orange simultaneously, then
› LED 1-4 will flash green in numerical sequence,
› LED 4 will remain green for approximately 15 seconds, then
› LED 5 will flash green for an instant, then
› LED 1-8 will illuminate dependent upon board A, switch SW1 and SW2 settings
To perform the DIP switch and LED test proceed as follows :
› note all current DIP switch contact positions
› set all SW1 and SW2 contacts CLOSED, LED’s 1-8 are off
› set all contacts of SW1 OPEN, LED’s 1-8 are RED
› set all contacts of SW2 OPEN, LED’s 1-8 are ORANGE
› return all contacts to their original settings
After a successful test, flip the BIC-II POWER switch to OFF. Return the board A, switch SW1,
contact 8 to NRM. Flip the POWER switch to ON.
The BIC-II will now perform a NORMAL self test, commencing normal operation upon successful completion.
Normal operation is not possible if switch SW1, contact 8 is left in the TST position.
NORMAL OPERATION
During normal operation (after a successful self test) LED1-8 indicate communication activity on the
respective Host, MillBus and product PORT(s).
› red indicates data is being transmitted from the BIC-II
› green indicates data is being received by the BIC-II
› orange means that data is both being transmitted and received.
A Host or MillBus LED which only flashes either red or green indicates faulty operation, check communication
cables and connections, if these LEDs remain off during attemped communication with the BIC-II check the
BIC-II I.D.# selected.
MILLBUS TRANSCEIVER THERMAL SHUTDOWN
BIC-II, board A, LED 9 MXTS, indicates the MillBus transceiver integrated circuit has entered a state of
thermal shutdown. After a cool down period, the transceiver will resume normal communication activity.
Should this condition be experienced, check all MillBus wiring for correct connections and polarity and ensure
the operating temperature does not exceed the maximum specified.
