Driver Enable Dip Switch
(off = logic 1, on = logic 0)
The individual switches in the off position
leaves the individual enable pin floating (in-
ternally pulled up or down) which enables
the driver. The switch in the on position ties
the high true enable pins to ground and the
low true enable pin (LLEN) to V
CC
thereby
disabling the individual drivers.
Receiver Enable Dip Switch
(off = logic 0, on = logic 1)
The individual switches in the off position
leaves the individual enable pins floating
(internally pulled down or up) which en-
ables the receiver. The switch in the on
position ties all of the enable pins to V
CC
even the high true TMEN. The TMEN pin is
always high no matter what position the dip
switch is in. To disable the TM receiver the

DIP switch must be offand the external pin

Decoder DIP Switch
(off = logic 1, on = logic 0)
The decoder DIP switch is configured such
that the switch in the off position allows the
decoder pins to float as well as the
notLOOPBACK pin. (all of these pins are
assumed to have internal pull-ups.) The dip
switch in the on position grounds each of
these pins.
DCE_DTE Selectable Switches
Switch bank 1 ON = ST driver outputs tied
to TxC receiver inputs and also tied to D-
SUB connector for remote evaluation.
Switch bank 2 ON = RRC driver outputs
tied to RRT receiver inputs and also tied to
D-SUB connector for remote evaluation.
