Modular Microphone Connections; Calrad Adapters - Apache Labs ANAN-100/D Manual

Left and right, or tip and ring are not marked on
RS adapter.

PTT plugs in adapter.
Note that JP6 has no jumpers by default, thereby disabling PTT.

Modular Microphone connections

Updated 09/07/2012
Hermes / ANAN-100/D+ SDR's have a 1/8" or 3.5mm stereo jack for microphone input and PTT. The following
instructions outline methods for interfacing common 8 Pin Modular microphones available from Kenwood, Yaesu
and others to Hermes / ANAN-100/D+. Since I don't have a Hermes / ANAN-100/D+ I am unable to test these
instructions with a working radio. Use at your own risk.
These instructions assume the user has properly installed and configured a P*SDR version compatible with
Hermes and installed the appropriate Hermes firmware for this version.
WARNING:
The FPGA and other components on the Hermes PCB can be damaged by Electrostatic Discharge (ESD). When
handling the PCB, you should take ESD precautions (i.e.. use a work bench with an antistatic mat on it and wear
a grounded wrist strap).
WARNING:
Remove DC power before opening housing to change jumpers. Failure to remove DC power could result in
damage to circuit boards.
Adapting some existing 8 pin modular Ham Microphones to Hermes 1/8" or 3.5mm stereo plugs without using a
soldering iron:

CalRad adapters:

CalRad ( http://www.calradstore.com/72-173.html ) makes several modular (RJ-45 or 8 pin Modular) to 8 pin
terminal block adapters which can be used to easily interface modular microphones to a 3.5mm / 1/8" stereo
plug required by Hermes / ANAN-100/D+ Cal Rad adapters are also available at
http://www.markertek.com/Connectors-Adapters/Data-Connectors-Adapters/RJ45-Adapters/Calrad-
Electronics/72-173.xhtml The Calrad 72-173 CAT5/CAT6 solderless R-45 Female to Terminal block provides a
very simple way to interface a Stereo jack to a RJ45 modular connector.
The CalRad 72-173 has a terminal block with 8 screw terminals on one end and a female 8 pin modular or RJ45
jack on the other end. It is just a matter of connecting 3.5mm / 1/8" stereo plug wires to the Calrad adapter
using a small screw driver. No soldering required.
