LED1 (Green) lit, indicates that the SMDR-E ETU is
receiving power.
2. Connection of SMDR
A. The SMDR-E ETU must be installed into
either OPT1 or OPT2 slot (or a combination
slot) of any CCU. Prior to installing the
SMDR-E ETU, ensure that switch SW1 is set
to the ON position and that the baud rate
switch, DIPl, is set to the proper position.
When installing the SMDR-E ETU, turn SW2
OFF
for
insertion of this ETU into the slot without powering
down the CCU.
B. Route the RS-232C connector ended cable
down and to the right side of the CCU in a
manner to avoid interference with the
insertion and the removal of ETUs and with
the 25pair cables from Jl - 53 connectors.
Remove the access panel on the right side of
the CCU, which covers three openings, to
mount RS-232C connectors. (See Figure
200-26).

APRIL, 1990
Mount the RS232C connector in one of the
openings using screws and nuts locally
provided. (See Figure 200-27.)
C. Connect a printer or other peripheral device
to the RS232C connector mounted on the
CCU in Step B. Secure the RS-232C male
connector from the printer or other
peripheral device with the screws provided
with the device.
D. Turn ON SW2 of the SMDR-E ETU.
A 25 pin RS-232C connector is provided with the
following pin configuration. (All pins are active
high).

240.8 LCR-EETU
The LCR-E ETU contains three switches, an LED and
a RS-232C connector ended cable.
1. Switches:
Switch 1, designated SWL, is used to connect
backup battery to the LCR-E MEMORY. This
switch should be set to the ON position to allow
memory retention during power failure or
brownouts, for approximately seven days.
Switch 2, designated SW2 RESET, is a slide
switch used to reset the LCR-E ETU,
with
interruption of all ongoing operation. This switch
is also used to busy out the ETU when the ETU is
