events recorders. See Figures
and
for dipshunt con-
figurations.
INSTALLING THE TERMINATION UNIT
The termination unit is ready to install if the dipshunts are
properly installed and configured, and the fuse is in place.
Installing the Fuse
You must verify that the fuse is installed and configure the dip-
shunts before installing the termination unit.There are four
dipshunts, two for each RS-232-C port.
Bailey ships a 0.25 amp, 250 volt fuse (Bailey part number
194776A12500) with each termination unit. If this fuse is
missing, install a fuse in the fuse holder (F1). Figure
shows
the location of F1 on the termination unit circuit board.

NOTE: IF AN ISOLATING MODEM IS USED, PROTECTIVE GROUND AND
SIGNAL COMMON GROUND OF THE MODEM CONNECTOR ARE TIED
TOGETHER, DIPSHUNT STRAP GND OF XU2 AND XU4 MUST BE CUT.
DOING THIS MAINTAINS THE ISOLATION OF DC COMMON AND SAFETY
