1. GENERAL
The ARA-100 is an adapter for the adaption of the CRM-008 or the HC-235
to any radio set. The power supply for the adapter is provided from the
CRM-008 or the HC-235 and the adapter is galvanically seperated from the
radio set.
The levels AF-in/AF-out as well as DX-in/DX-out can be adjusted by means
of a potentiometer. A built-in headset allows the monitoring of the
deciphered speech signal and sidetone.
The existing audio gear of the radio set can be connected to the ARA-100,
or if this is not required the function is undertaken by the CRYPTO-
MICROTEL AHF-100 connected to the CRM-008 or the HC-235.
The ARA-100 is intended for both fixed and mobile applications.

2. INSTALLATION
The 10 pin multipole connector of the ARA-100 must be connected to the
output DATA of the CRM-008 (HC-235). The plug is mechanically polarized
and care must be taken to correctly align the plug before pushing it
home. The plug is self-locking and may be released by pulling its front
sleeve rearwards.
2.1. Receive Unit
Connect the audio output (phone) of the radio set (0 dBm output pre
ferred) with a shielded cable to the terminals 28 and 29 of the ARA-100,
29 being the "hot" and 28 the common or shield terminal.

Connect the modulation line of the radio unit (input without AGC pre
ferred) by means of a shielded cable to the ARA-100. It should be noted
that for units equipped with carbon microphones or 600 ohm inputs the hot
line goes to terminal 27. For units with dynamic microphones, the hot
line goes to terminal 25. Terminal 26 is the common or shield. The
keying li ne (push- to -talk) sh ould be con nected flo at ing to ter minals
23 and 22 or 23 and 24 respectively.
2.3. Audio Gear
When using the handset AFH-100 with the CRM-008 no further audio gear
is required. If, however, existing units of the radio se t ar e to be
used, the earpiece must be connected to the terminals 11 and 12 of the
ARA-100. Dynamic microphones should be connected between terminals 13
and 14. Carbon microphones should be connected between terminals 15 and
16. In addition the jumpers C-F, H-L, K-G and M-I must be connected
with wire bridges for carbon microphones. The push-to-talk (PTT) button
of the microphone should be connected to terminals 18 and 19. In addition
the jumper P-Q must be connected with a wire bridge.
2.4. Plain/Crypto Remote Control.
In place of the PTT button of the microphone, the terminals 18 and 19
can be used for Plain/Crypto remote control via a switch. For this type
of use the jumper P-N must be connected with a wire bridge.
2 . 5 . Vo x Co n t r o l .
If the radio euipment posseses a Vox control, this should be connected to
terminals 20 and 21. In addition the jumpers A-D and B-E must be
connected with wire bridges.
2.6. Sidetone
With a wire bridge between the jumpers R-S the sidetone (own voice) can
be switched in.
