Mechanical Connections
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 !
The software controls the phone via a separate adapter connected to the serial
port of the PC and to the telephone’s M2BUS (DAU–2 and XCM–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.
The PKD–1 should not effect devices working with it. If some errors occur (er-
rors in printing are possible) please try printing without the PKD–1. If printing is
OK without the PKD–1 please contact your dealer. We will offer you a new
PKD–1 in exchange for your old one.
