Installation
Select an appropriate location, accessible to and within six feet of an AC power outlet. Use
a “Straight Through”, shielded cable, between the attached terminal device and the 1084
(CTS LD-128K) (
The 1084 has a female DB-25 Connector). Connect the RS-232 terminal
device to the connector marked J4. The 1084’s (CTS LD-128K) are connected using a
standard, crossed, RJ45 telephone cable. Plug the cable into connector J2 or J3, which are
in parallel with each other, to allow connection of multiple 1084’s (CTS LD-128K) for Multi-
Point operation. Standard Telephone cords can be used provided the wire pairs are
reversed.
Caution: Never connect the RJ-45 Line connectors to
the Public Switched Telephone Network!
Equipment Grounding (SW2-6)
SW2 Position 6 provides for grounding interconnection in those systems requiring a
connection between (Frame Ground) and (Signal Ground).

Point to Point / Multi-Drop Connectors J2 & J3
J2 and J3 are parrallel RJ-45 connectors. Pin 1 on J2 is connected to pin 1 on J3, pin 2 on
J2 is connected to pin 2 on J3 and likewise for the remainder of the pins. This allows two
1084 (CTS LD-128K) to be connected by simply installing a standard crossed telephone
cable between the units. When adding addtional units for a Multi-Drop application, chain
the J2 or J3 from one unit to another, using a standard straight through telephone cable. It is
not important which connector is used, as J2 and J3 are electrically eqivalant to each other.
All of the Slave 1084 (CTS LD-128K) receivers (pins 7&8), must be tied together and
connected to the transmitter of the Master 1084 (CTS LD-128K) and all of the Slave LD-
128K transmitters (pins 1&2), must be tied together and connected to the receiver of the
Master 1084 (CTS LD-128K). (see Appendix)
