PATTONELECTRONICSCO. 1205P INSTALLATION AND OPERATIONS MANUAL
CHAPTER 1 - OPERATION
The1205P(CTSME-V.35)isa costeffective solutionforinterconnectionofV.35terminal
deviceslocated in proximity of each other. The use of two modems is eliminated with a
resultingcostsavingsto theuser. The1205P(CTSME-V.35) complieswiththe CCITTV.35
balancedinterfacespecification. Two34 pin V.35 (MR-34) connectors are provided to
interfacetotheV.35terminals.
Clocking
TheModemEliminatorcanbeeitherinternallyorexternallyclockedindependentlyoneach
Port. Ratesupto2.048Mbps areprovided bytheinternal baudrate generator. Thegenerator
willprovideclocksforbothterminalandinsurethedataissynchronizedwiththeRXClockin
bothdirections.
Delaying CTS
Request to Send (RTS) is looped back to Clear to Send (CTS) on each Port. To allow
terminalsrequiringCTSdelaystofunctionproperly,selectabledelaysofConstant,0mS,8mS
and50mS of RTS to CTSdelay is provided. Each Port ins individuallyconfigured for CTS
delay.
Controlling Carrier Detect
RTS on each port is also routed to Data Carrier Detect (DCD) on the other port. When DCD
is set to follow RTS, the same delay that is added to CTS is added to DCD. DCD can be
alsobeforcedtoconstantactivebyconfigurationswitches.

otherport. DSRcanbeconfigured to follow the DTR or can be forced to be activeall thetime.
Power
110or220 Volt operation is provided by a convenient switch locatedon therearpanelof the
1205P (CTS ME-V.35). Simply install the proper fuses (110VAC - .16ASB, 250V or 220VAC
-.8ASB,250V)and powerplug forthecountryofuse andselect theproperline voltageand
theunitisreadyforoperation.
Approvals
Safetyapprovals for UL & CSA havebeen granted allowing the ModemEliminator. FCC Part
