INSTALLATION
INIIR01 INFI-NET TO INFI-NET REMOTE INTERFACE INSTALLATION
I-E96-607A
3 - 9
This signal is fed through the termination unit cable to the P3
connector on the NIS module. The power system status input
is a TTL-compatible signal. A five-VDC signal (logic high) on
power system status indicates good status; a zero-VDC signal
(logic low) indicates bad status. When no connection is made to
either of the power system status inputs, a pull-up resistor on
the NIS module puts a logic high on the power system status
input, thereby reporting good status.
INIIT02 Module Dipswitches
There are two user-configured dipswitches and six jumpers on
the INIIT02 module that set the module operating characteris-
tics. Figure
shows dipswitch locations on the INIIT02 mod-
ule circuit board.
INIIT02 MODULE JUMPERS
There are six jumpers on the INIIT02 module. Jumpers one
through four have no usable function and must be set as
shown in Figure
. Jumper J5 opens pin four of P1 so that it
has no continuity with the module mounting unit. Pin four of
P1 is normally used for Controlway. Older systems use this pin
for -30 VDC. Refer to
INIIR01 Interface Mounting Unit Prep-
for more information on setting J5 and installation
options. See Figure
for the location of the machine fault
timer (MFT) jumper posts. These jumper pins must be open so
that that MFT timer is enabled.
INIIT02 TEST/MODULE ADDRESS DIPSWITCHES SW3
Dipswitch SW3 is an eight-position dipswitch that sets the
module address and operational mode. Table
option settings. Record the settings in the space provided.
INIIT02 DIPSWITCH SW4, OPTIONS
Dipswitch SW4 is an eight-position dipswitch that determines
the operating options of the module. Table
lists the options
and dipswitch settings. Record the option settings in the space
provided.
CAUTION
Always operate the IIT module with the machine fault timer cir-
cuit enabled. Unpredictable module outputs may result if the
machine fault timer circuit is disabled. These unpredictable
module outputs may adversely affect the entire communication
system.
ATTENTION
N'utilisez jamais un module IIT sans l'usage de sa minuterie de
détection de défaillance (MFT). Sinon, les sorties du module
pourraient prendre des valeurs ou des états imprévisibles. Le
comportement imprévisible des sorties pourrait perturber la
totalité du système de communication.
