INNIS01 DIPSWITCH SW3, LOOP MODE
Dipswitch SW3 pole one determines the node type (refer to
Table
). Set pole one to the one position for all INFI-NET to
INFI-NET interfaces. Pole two enables or disables ROM check-
summing. Bailey recommends that the NIS module be installed
with checksumming enabled to take full advantage of the
on-board diagnostics. Pole three enables internal testing which
must be disabled for normal operation. Pole four in conjunc-
tion with pole three makes the node appear to be busy to other
nodes. Pole five enables the channel idle condition display for
the front panel LEDs. If channel one is idle, the A group of
LEDs will flash on and off twice per second. If channel two is
idle, the B group of LEDs will flash. The channel idle display
serves as a warning that a loop integrity problem exists. Pole
six enables diagnostic tests which preclude normal NIS module
operation. Poles seven and eight determine loop speed.
NOTE: Testing modes involving poles three, four and six interfere
with normal node operation.

NOTES:
1. 0 = CLOSED or ON, 1 = OPEN or OFF.
2. The central loop must have a loop address of 1. Valid satellite loop addresses are 2 through 250.
