11 For MCA, set option plugs to the required configuration, RS-232 or
V.35. The factory default is RS-232.
12 Tilt the MPDA or MCA circuit board up and insert the DB-25 connector
socket into the breakout section. Then slide the board connector
end-first under the tabs in the footstand assembly and position it over
the locating pins. Position and lower it completely onto the telephone
footstand assembly. Insert the two self-tapping Phillips-head screws
supplied with the MPDA or MCA into the mounting holes and tighten
them with a #1 Phillips screwdriver.
13 Plug one end of an 8-conductor line cord supplied with a TELADAPT
adapter in the jack J1 of the MPDA or MCA (latch tab facing down) and
plug the other end of the line cord into the data jack in the base of the
telephone. Make certain the latch tab of each cable end is firmly
snapped into place.
14 Carefully route the excess cable so that it will not become pinched
between the footstand and base.
15 Reassemble the base and footstand assembly sections, ensuring that
the footstand is firmly seated on the base.
16 Tighten the screws
• Reconnect all cords, connect the new 24v AC transformer to the
set.
• Plug in the new transformer into the 110v AC commercial
electrical outlet.
• Place the telephone in the normal operating position.
Note 1: Place the label supplied with the MPDA or MCA on the
outside of the bottom cover of the telephone. This allows proper
identification and tracking of the option level of the set.
Note 2: If an ADM3, ADM5, or ADM11 terminal is used in conjunction
with the DB-25 connector-C interface connector in the Asynchronous
Programmable Data Adapter, pin 22 in the DB-25 connector cable
must be disconnected. These ADM terminals will go into test mode if
this pin is not disconnected.
