EMISSION REQUIREMENTS
FCC CLASS A
Warning: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of FCC rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expence.
CANADIAN EMISSIONS
This digital apparatus does not exceed the Class A limits for noise emmissions from a
digital apparatus set out in the Radio Interference Regulations of the Canadian Department
of Communications.
Le present appareil numerique n’emet pas de bruits redioelectriques depassant les limites
applicables aux appareils numeriques de la Class A prescites dans le Reglement sur le
brouillage redioelectrique edicte par le ministere des Communications du Canada.

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.
