CHAPTER 1 - OPERATION
The 1084 (CTS LD-128K) is an RS-232 Line Driver. This device is a cost effective solution
for interconnection of Synchronous or Asynchronous, Point to Point, or up to 32 Multi-Point,
terminal devices. (Distances of up to 4000 feet, at 128Kbps may be acheived, using 24ga.
wire.)
Front Panel
The power indicator, marked PW on the front panel is green and indicates when AC voltage
is applied to the unit. The two adjacent green LED indicators illuminate in conjunction with
Send Data (SD) and Receive Data (RD). Request to Send (RS), Clear to Send (CS),
Carrier Detect (CD) and Anti-Stream (AS) status LED’s are also provided to give a clear
visual indication of the 1084’s (CTS LD-128K) operational status. The Digital Loop Back
switch provides a convient means to verify operation of the data communication circuit.
When the button is not depressed (BLACK), the 1084 (CTS LD-128K) operates normally,
providing communication from end to end. When in (YELLOW), the 1084 (CTS LD-128K)
provides bilateral looping to facilitate testing of the line driver and communication circuit
from either end.
Point to Point / Multi-Point Operation
The 1084 (CTS LD-128K) utilizes RS-485 tristate drivers and receivers. Both Switched
Carrier and Constant Carrier operation are possible. When Switched Carrier is selected, up
to 32, 1084 devices may be connected together to form a Multi-Drop network. Distance from
the master 1084 to the last 1084 in the network are dependent on data rate selected and the
gauge of wire used to connect the units. The higher the data rate and thinner the gauge of
wire used, the shorter the communication distance possible. During Constant Carrier
operation, the 1084’s are connected in a point to point configuration. As with Multi-point
operation, the higher the data rate and thinner the gauge of wire used, the shorter the
communication distance possible. The 1084 can also be used point to point in the switched
carrier mode.

“Switch on Data” Mode
To allow terminals that do not respond to RS and CS control leads to operate in a MultiPoint or Point to Point network, the “Switch on Data” mode has been provided. When a
terminal sends data transitions, the 1084 (CTS LD-128K) will bring up its carrier and start to
transmit. When the data transitions stop for a period greater than the selected “No Data
Time-out” the carrier will drop and the 1084 (CTS LD-128K) will return to an idle state. CS
is constant when in “Switch on Data” Mode.
Clocking
Rates up to 128Kbps are internally generated by the 1084 (CTS LD-128K) for Transmit
clocking. Clocking may also be taken from an external device on the External Transmit
Clock Lead, pin 24, to facilitate tail circuit applications. To ensure synchronization of clock
through a system, Receive clock may also be utilized as the Transmit clocking source
(slave clocking).
Four Wire / Two Wire Operation
Half duplex 2 wire operation as well as 4 wire full duplex operation is selectable via
configuration switches.
Testing Modes
Local digital loop-back is easily selected via a front panel mounted switch. A positive visual
indication is provided when the 1084 (CTS LD-128K) is in loop-back mode. The data line is
looped bilaterally to allow both the local terminal and the remote terminal to be tested when
in 4 wire mode.
CTS Delays
CTS can be configured to respond to RTS regardless of the state of the transmitter. RTS to
CTS delays can be set to constant, 0mS, 8mS or 50mS.
Anti-Streaming
When a terminal in a Multi-drop network fails, with the RS signal lead active, the attached
LD-128K will remain transmitting. This “Streaming” terminal will cause the entire network to
fail. To prevent this type of failure, the 1084 (CTS LD-128K) provides Anti-Streaming
protection. When Anti-Sreaming is enabled, the control logic will turn off the 1084’s (CTS
LD-128K) transmitter after seeing an RS signal for the selected period of time. The
transmitter will not turn on again until the RS signal is released by the terminal.

CHAPTER 2 - SETUP AND INSTALLATION
Power Connection
Before connecting the 1084 (CTS LD128K) to a AC power source the top cover
must be installed and secured with the
supplied #4-32 screws. The unit is
supplied with a 110/220V voltage switch,

EXAMPLE: United States of America; set to 110V. The unit is supplied with a IEC power
connector next to the voltage select switch, plug the power cord into the connector until it is
firmly seated. You may now connect the power cord into your AC outlet.

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 MultiPoint 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).
Set to
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 LD128K transmitters (pins 1&2), must be tied together and connected to the receiver of the
Master 1084 (CTS LD-128K). (see Appendix)
