CHAPTER 1 - O
PERATION
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.
