The
15 pin band data outputs on the ORION
transceiver use open collector outputs for band data information
to be sent to accessory devices for bandswitching
information. Our 420
Hercules II
amplifier and 253
autotuner
were set up to use the bandswitching from the SPORT interface on
the rear of the Omni-V,
Omni-VI,
Omni-VI
Plus,
and Paragon
II,
which required a voltage going high for bandswitching.
The
model 311
converts the open collector outputs on the ORION
to the active high inputs required by the model 253
and
model 420.
The output voltage per line is approximately 13.5 Vdc and each
line is capable of driving loads requiring 40 mA (each line is
current limited at 40 mA). Each output uses an MMBT3906
transistor with breakdown voltage of 40 Vdc.
The
input to the box uses a 15-pin AMP connector like the 15-pin band
data connectors on the rear panel of the ORION.
The output of the box is a 25-pin D-sub as used on the rear of the
Omni-V,
all Omni-VI
variations and Paragon
II.
Please
note that connecting cables from the 25-pin D-sub to either the 420
Hercules II
or the 253
are discontinued and no longer available. To use the
interface with the ORION
to these discontinued models, you must either retain the same
cable as used with your previous transceiver or fabricate your
own.
A
15-pin to 15-pin cable to connect the ORION
band data output to the input of the band data converter is
provided with the
311.
