Example Adaptation; Microphone Connector Database; Grounded Wrist Strap And An Anti-Static Mat - Apache Labs ANAN-100/D Manual

WARNING: The CalRad adapters numbering scheme is the reverse from
http://homepage.ntlworld.com/rg4wpw/date.html pin-outs for Yaesu and Kenwood radios.
The following pin assignments use the CalRad pin numbering scheme, not the mic numbering scheme.
Example adap t ation :
Adapting a Yaesu MH-31A8J (FT-817) microphone for use with Hermes 1/8" / 3.5mm jack:
1. Obtain a Yaesu MH-31A8J 8 pin modular microphone. Used by Yaesu FT-817 and others.
2. Obtain a 1/8" / 3.5mm stereo plug with attached shield, and 2 stranded wires, neoprene covered, typical. RS
4202497 or equivalent. Tin wire ends before use.
3. Obtain CalRad 72-173 adapter or equivalent.
4. See http://homepage.ntlworld.com/rg4wpw/date.html for details on the pinout of MH-31A8J microphone.
Note that the CalRad numbering scheme is different than the numbering on the above web page.
5. Using an ohm meter on the stereo plug wires, identify which wire colors correspond to the stereo plug tip and
stereo plug ring.
6. Connect the Stereo Plug Tip wire to CalRad pin 5 (Mic Audio).
7. Connect the Stereo Plug Ring to CalRad pin 6 (PTT).

8. Connect the Stereo Plug shield to Cal Rad pin 7.
The Hermes Jumpers JP4, JP5, and JP6 must now be configured to accept the Yaesu MH-31A8J mic as
wired above.
1. Remove DC power from Hermes ANAN-100/D+.
2. Open Hermes / ANAN-100/D+ housing using a grounded wrist strap and an anti-static mat. Locate
the following jumpers and change as needed:
3. JP4, Mic audio on Tip, jumper pins JP4-2 and JP4-3 (Hermes Default).
4. JP5, Electret mic, Do not install jumpers (Hermes Default).
5. JP6, install jumpers between pins JP6-1 and JP6-2 placing PTT on ring.
6. Close Hermes / ANAN-100/D+ housing.
Refer to
http://svn.tapr.org/repos_sdr_hpsdr/trunk/Hermes/Documentation/Hermes_User_Manual_V1.6.pdf to
set jumpers for other intended uses.
Note: The CalRad 72-RJ45-T CAT6 Solderless RJ45 to terminal block pigtail is similar but requires the
addition of a double female RJ45 adapter. The terminal block end has a rather nice shroud and tie down
facility for attaching your stereo plug cable.
