INNIS01 NETWORK INTERFACE SLAVE MODULE CONFIGURATION
I-E96-613A
3 - 5
Dipswitch SW3 pole one determines the node type. Set pole one
to position one for IPR interfaces. Pole two enables or disables
ROM checksumming. 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 con-
junction with pole three, makes the node appear to be busy to
other nodes. This condition is used by Bailey Controls Com-
pany personnel only. Pole five enables the loop idle condition
display for the front panel LEDs. If loop one is idle, the group A
LEDs will flash on and off about twice per second. If loop two is
idle, the group B LEDs will flash. The loop idle display is
intended to serve as a warning that a loop integrity problem
exists. Pole six enables diagnostic tests that preclude normal
NIS module operation. Poles seven and eight determine loop
speed and loop mode.
NOTE: Testing modes involving poles three, four and six interfere
with normal node operation.
DIPSWITCH SW4 - I/O EXPANDER BUS ADDRESS AND
COUNTERS
The NIS module can have an I/O expander bus address from
zero to seven. Poles one through three of dipswitch SW4 set the
I/O expander bus address of the NIS module (see Figure
Refer to Table
for I/O expander bus address settings. Poles
four through eight set the address of the on-board event and
error counters that the NIS module displays using the group A
and B faceplate LEDs (see Figure
). LED B8 is the most sig-
nificant bit. LED A1 is the least significant bit. Table
lists
the event counters. Table
lists the error counters. Record
the dipswitch SW4 settings in the space provided.
Example of Counter Usage:
A counter setting with a hexadecimal value of 09 keeps track of the number of multicast
messages received excluding those originated. To display this counter on the front
panel LEDs, set dipswitch SW4 as follows: pole 4 = 0, 5 = 1, 6 = 0, 7 = 0, and 8 = 1.
7/8
0/0
10 Mbaud INFI-NET mode.
0/1
2 Mbaud INFI-NET mode.
1/0
Unused.
1/1
500 kbaud Plant Loop mode.
NOTES:
1. 0 = CLOSED or ON, 1 = OPEN or OFF.
2. Shaded areas designate normal operating positions.
3. Applies to INNIS01 modules with revision B or later ROMs. For modules with revision A ROMs, poles 4 through 6 must be set to 0.
