Equipment Setup
Caution: Make sure that you have switched off the PC and the printer before
making connections !
Caution: Do not connect the PKD–1 key to the serial port. You may damage
your PKD–1 !
Attach the protection key PKD–1 to parallel port one (25–pin female D–connec-
tor) of the PC. When connecting the PKD–1 to the parallel port be sure that you
insert the PC end of the PKD–1 to the PC (male side). If you use a printer on
parallel port one, place the PKD–1 between the PC and your printer cable.
Next connect the M2BUS adapter to the serial port (RS–232) of the computer.
In case you are using a 9–pin serial port (normal with an AT set) use the mating
adapter supplied with the M2BUS adapter.
Attach one end of the XCM–1 modular cable to the DAU–2 PC/M2BUS adapter
and the other end to the JBS–7 service box. Use suitable adapter, SCS–1 ser-
vice cable when the covers of the phone are in place, JBS–8 test frame with the
phone covers off, and attach it to the phone. Then connect it to the service box.
