Configuration Straps
The configuration straps set the line clock polarity. When you
set the straps in the POS position, data changes at the rising
edge of the clock pulse signals. When you set the straps in the
NEG position, data changes at the falling edge of the clock pulse
signals. Straps are set for POS edge trigger from factory and
should not be changed in the field.
A Power Input Decoupling Network
The power input decoupling network is a capacitor array that
filters and isolates noise from the +5 VDC operating power. The
46113 SynchMaster module power supply supplies operating
power to the 46112 and 46113 SynchMaster modules. If more
than one 46113 SynchMaster module is at a location only one
46113 SynchMaster module supplies power to its associated
46112 SynchMaster module.

CIRCUIT DESCRIPTION
N
OTE
:
When the unit initially powers
up, the TX REPEAT LED blinks
on and off at a one second inter-
val if you set any 46113 Synch-
Master port switches incorrectly.
If this happens, recheck the
46113 SynchMaster module
switch settings.
