JUMPERS J1, J2, J4, J5
Jumpers J1, J4 and J5 define module functions and operation.
Jumper J1 determines if the RS-232-C diagnostic port (P4)
operates as data communication equipment (DCE) or data ter-
minal equipment (DTE). Jumper J4 enables the machine fault
timer (MFT). Jumper J5 disengages -30 VDC from the module
when installing it in an MMU card cage that uses -30 VDC.
Jumper J2 is set at the factory and should not be changed.
Refer to Table
for those jumpers that have default set-
tings.

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.
