3.1
OPTION SELECTION
Jumper options that control two operating parameters, data
rate and audio output, are provided on the CUTS Module.
The port
address for the module is selectable with seven switches.
Use the
following selection instructions along with the assembly drawing in
Section VI.
3.2
PORT ADDRESS SELECTION (DIP Switch, Sl)
One of 130 possible port addresses, from
¢
through FA (hex),
254 (decimal), for the CUTS is selectable with the first seven DIP
switch positions in location Sl.
All Processor Technoloqy software is written for a CUTS port
assignment of FA (hex).
To configure your CUTS for this port, set
Switch No.2 (Sl-2) to OFF and Switch NO's. 1 (Sl-l) and 3 through 7
(Sl-3 through Sl-7) to ON.
To select another port, set Sl-l through Sl-7 as required
for the desired address.
with these switches the address increases
from
¢
(all seven switches open) in a binary fashion to 254, decimal,
(all seven switches closed).
When setting these switches, keep in
m~nd
that 1) Sl-7 and Sl-l are the most and least significant bits
respectively and 2) a closed switch is equivalent to a binary 1.
3.3
AUDIO OUTPUT SELECTION
The A, B, C, D jumper arrangement (to the left of U16) de-
termines the audio output signal supplied to Jl and J2.
Three
choices are available:
1) a 5 V peak-to-peak signal for driving
digital recorders, 2) a 250 mV signal for driving the auxiliary in-
put to an audio cassette recorder, and 3) a 50 mV signal for driving
the microphone input to an audio cassette recorder.
For audio cassette recorders, the auxi-
liary input is preferred and recommended
over the microphone input.
To select the digital recorder output, install a jumper
(#24 bare wire is
recommended~
between Augat pin A and the mounting
pad labeled D.
To select the auxiliary output to drive the auxiliary input
(the recommended input) to an audio cassette recorder, install a
jumper (#24 bare wire is recommended) between Augat pins A and B.
