is recommended. For correct operation a
minimum current of 2 mA is recommended.
Access to the remote control inputs is pro-
vided by means of a 10-pin male “header”
connector which is located on the Model
46A’s circuit board. Refer to Figure 3 for
a view of the connector’s location. The
“keyed” and “shrouded” header follows
a common industry-standard specifica-
tion: 2 rows of five pins each with 0.1 inch
between rows and pins. The mating con-
nector is intended to be an insulation-dis-
placement (IDC) socket connector such as
the AMP 746290-1. The connector would
be “crimp” terminated onto a piece of
10-conductor flat ribbon cable. This rib-
bon cable can safely exit the Model 46A
by laying flat between the chassis and the
cover. The ribbon cable can then “fan out”
to loose wires or, better yet, be terminated
onto another connector such as a 9-pin
D-subminiature type.
There are several ways of preparing to
connect to the remote control inputs. The
easiest means is to purchase an intercon-
necting cable assembly from Studio Tech-
nologies, Inc. The cable assembly consists
of a length of ribbon cable with a 10-pin
socket on one end and a 9-pin D-sub fe-
male on the other. Contact the factory or
check the website for details. Alternately,
a competent technician can easy fabricate
an appropriate remote control input inter-
connect wiring assembly. An example of a
partially pre-made assembly is part number
A1AXH-1036G-ND which is available from
Digi-Key (www.digikey.com).
It’s important to ensure that the source
of the remote control signals can meet
the Model 46A’s logic-state and timing
requirements. The Model 46A recognizes
an idle remote control input as one that
has no current flowing through it. An
active remote control input is one that
