CHAPTER 3 - SETUP AND INSTALLATION
3.1
POWER CONNECTION
It is
very
important to check that the unit is set to the correct voltage setting for your
application before applying AC power. Located on the rear of the unit you will find a rotary
110/220 VAC switch. Using a coin or small screwdriver,
gently
turn the switch to the
appropriate power position as required for your installation (110 or 220 VAC).

3.2
INSTALLATION
Connect the main input data feed source into the
INPUT
port DB-15 female connector. The
output ports are marked
PORT 1
through
PORT 8
. Connect from one to eight DTE V.11
(X.21) compliant devices into the sub-channels ports on the back of the
V.11 LS
.
3.3
CASCADING AND TERMINATION RESISTORS
If more than one
V.11 LS
are to receive Data, Clock and Indicate from the same source, a
shielded DB-15 one-to-one extension cable with a male DB-15 on one end and a female DB-
15 on the other end can be used to link the
V.11 LS
together. The box
furthest
from the
source of the data and clock should have jumpers
JMP2
,
JMP3
and
JMP4
moved to the
opposite
position of the factory default setting for proper termination.
High quality shielded cables are recommended for box to box cascading. The cabling should
be a twisted pair with a wire mesh shield. All signal pairs should be kept together for clean
quality signals. We recommend Black Box EGM16E or equivalent cable with metal hoods.
