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 1206P (CTS ME-X.21) is a cost effective solution for interconnection of X.21
terminal devices located in proximity of each other. The use of two modems is
eliminated with a resulting cost savings to the user. The 1206P (CTS ME-X.21)
complies with the CCITT V.11 balanced interface specification. Two 15 pin DB-15
connectors are provided to interface to the X.21 terminals.
Clocking
Clocking at rates up to 768Kbps with the low speed version and up to 2.048Mbps with High
Speed Option are provided by the internal baud rate generator. The generator will provide
clocks for both terminal and insure the data is synchronized with the S Clock in both
directions.
Delaying INDICATE
Control (C) is looped back to Indicate (I) on each Port. To allow terminals requiring I delay to
function properly, selectable delays of Constant, 0mS, 8mS and 50mS of C to I delay is
provided. Each Port is individually configured for I delay.
Power
110 or 220 Volt operation is provided by a convenient switch located on the rear panel of the
1206P (CTS ME-X.21). Simply install the proper fuses (110VAC - .16ASB, 250V or 220VAC
- .8ASB, 250V) and power plug for the country of use and select the proper line voltage and
the unit is ready for operation.

Approvals
Safety approvals for UL, CSA & TÜV have been granted allowing the Modem Eliminator to be
used virtually anywhere in the world. FCC Part 15 class A emissions approvals insure the
Modem Eliminator will not interfere with any of the other equipment in your data center.
CE NOTICE: The CE symbol on your Patton Electronics equipment indicates that it is in
compliance with the Electromagnetic Compatibility (EMC) directive and the Low V oltage
Directive (L VD) of the Union European (EU). A Certificate of Compliance is available by
contacting T echnical Support.
Available Options
1206P (CTS ME-X.21) is available in both stand-alone subset or rack-mountable versions
(1206PRC). Various configuration of the interface are also available from the factory. The
1206PRC fits into the Model 1010R16 16 Card Rack Assembly.

CHAPTER 2 - SETUP AND INSTALLATION
Power Connection
Before connecting the 1206P (CTS ME-X.21) to a AC power source the top cover must be
installed and secured with the supplied #8-32 screws. The unit is supplied with a 110/220VA
voltage switch, turn the switch with a coin or screw driver to the appropriate voltage for your
country. EXAMPLE: In the United States of
America; set to 110VA. 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.

The 1206P (CTS ME-X.21) is configured prior to shipment with the switches set to the
following default positions:
Switch 1 - 2, 3, 5 and 6 to OFF, 1 and 4 to ON.
Baud Rate = 64Kbps
Switch 2 - 1, 3, 4 and 6 to OFF, 2, and 5 to ON.

INSTALLATION AND OPERATIONS MANUAL1206P
Disassembly
Remove the top cover by unscrewing the phillips head screws located on the left and right
sides of the 1206P (CTS ME-X.21). The configuration switches and Jumpers are located on
the PCB as indicated on the strapping guide in the Appendix of this manual. After the switch
selection activity is completed,
re-install the top cover BEFORE connecting to an AC
power source.
Installation
Select an appropriate location accessible to and within six feet of an AC power outlet. The
outlet must have a ground pin receptacle for product warranty.
"Straight Through"
shielded
cables, terminated in male X.21 (DB-15) connectors should be used to connect the two
terminals to the 1206P (CTS ME-X.21). Set the switches and Jumpers to match the required
configuration using the descriptions in this chapter and the strapping guide in the appendix.
Equipment Grounding (JP4)
JP4 provides for grounding interconnection in those systems requiring a connection between
(Frame Ground) and (Signal Ground). Connect ONLY if required.
IND Delay, Port 1 (SW2-1,2)
SW2 position 1 and 2 selects C to I delay for the terminal connected to PORT 1. C (pins 3,10)
