Mechanical Connections
CAUTIONS: Ensure that you have switched off the PC and the
printer before making connections.
Do not connect PKD–1 to the serial port. This could
damage the PKD–1.
The software controls the phone via a separate adaptor connected to the
serial port of the PC and to the phone’s M2BUS (DAU–2 and XCM–1).
Attach the protection key PKD–1 to parallel port one ( 25–pin female
D–connector ) of the PC. When connecting PKD–1 to the parallel port
ensure that you insert the PC end of PKD–1 to the PC ( male side ). If
you use a printer on parallel port one, insert PKD–1 between the PC and
the printer cable.
Using PKD–1 should not adversely affect the operation of other items of
test equipment. If errors do occur try printing without the PKD–1
connected. If printing is now ok please contact your dealer.
Attach one end of the modular cable, XCM–1, to the PC/M2BUS adaptor,
DAU–2, and the other end to the service box, JTS–1. For servicing the
phone with the covers in place the service box should always be used.
When the covers are removed for servicing the Service Cable, SCC–5,
should be connected between JTS–1 and the accessory connector of the
system module.
The RF cable should be connected between the RF connector of the test
set and the appropriate connector on JTS–1. When the phone covers are
removed the RF connection on the extension cable should be used
instead.
For audio measurements connect the audio cable, ADS–1, as follows:
 –EAR line to AF INPUT of test equipment
 –MIC line to MOD GEN OUTPUT of test equipment
