\r\n This is an attempt to gather as much information on the peltor rally intercoms and headsets as possible into one place. It is intended to be a living document, and I encourage everyone to add in their information and links. I will add the information to this post as it is flushed out. Please point out any incorrect or incomplete information you see and add anything new you know.
\n
\n Intercom Models:
\n
\n FMT110 (discontinued, replaced by FMT120 ?)
\n
  • Single volume
  • Switch to pad driver’s mic by -10dB
  • RCA mono audio-out.
  • 9V battery powered.
  • Optional FC15 – 12v power adapter.
FMT120
\n
  • Separate volume for driver and co-driver.
  • Switch to pad driver’s mic by -10dB.
  • RCA mono audio-out.
  • PTT button input
  • TA5F in/out connector for radio integration.
  • 9v battery powered.
  • LED Power indicator.
  • Optional FC16 – 12v power adapter.
FMT200
\n
  • Push button (vs. knob) controls
  • Separate volume for driver and co-driver
  • Separate settings for Stage and Road sections (Stage pads driver mic by 10dB, radio, phone and VOX are disabled).
  • VOX level controls
  • LED Power, level, VOX and mode indicators
  • 9V battery/12v vehicle dual-powered
  • RCA mono audio-out
  • DB-9 Radio interface
  • DB-9 GSM Phone interface (may work with others?)
  • There appear to be dual inputs for the headsets, one U-174/U and the other a TA5F

\n Headset Models:
\n
  • MT632 Open Face headset
  • MT63 Full-Face headset
  • MT3H6-02 Replacement set for G7/G77/G78 helmets
  • MT3H6-01 Replacement for G90 helmet
  • MT7H79A Practice headset

\nThis has several ramifications. Some U.S. organizations do not recognize BSI (LeMONS - they do recognize an FIA standard, but it is not the one on my helmet, mine was made in 2006).
\n
\nCARS recognition of BS 6658-85 type A/FR is due to expire December 31, 2013. CARS follows FIA. NASA also usually follows FIA, but there is nothing in the 2011 NASA rules about the BSI spec expiring for CARS. I have seen no new BSI spec (if there even is one) Peltor helmets for sale.
\n
\nRA/RC is also silent of this (but seems less tied to FIA)...
\r\n \r\n
\r\n
\r\n
Other models are available for boating, with different certifications, etc, but are not applicable to rally in North America.

\nThe Peltor FMT200 is equipped with a potential-free connection between pins 3 and 8 for the
\nPTT function to be used with a com radio. A contact between pins 4 and 7 creates a connection
\nbetween 3 and 8.\r\n \r\n

\n Compatibility:
\n
  • Terraphone - Peltor helmets can be used in Terraphone intercoms with an adaptor. Most (passive?) can only use one Peltor headset at once, while some (active adaptor) can use two. Terraphone headsets cannot (to the best of my knowledge) be used on Peltor intercoms due to the shared mic/speaker ground.
  • Terraphone Pro - Direct compatibility (?)
  • Stilo - ?

    \r\n \r\n July 30, 2011 - I\'ve been waiting for this for a while.
    \n It\'s a cable that will let me plug an iPod or iPhone into the Peltor FMT120 intercom. This cable isn\'t available in North America, despite the fact that all the resellers of the FMT120 use the same product description that includes this feature. This says something about the size of the Peltor rally intercom market in North America, I suspect. I had to bring this cable in from Demon Tweaks in the UK, which wasn\'t cheap.
    \nStill, it\'ll let Janel and I make phone calls using the intercom as well as listen to music on long transits. If you look at the cable as a stereo system, it was a pretty good deal! Less than an iPod interface for our BMW, for example.
    \nSince this thing can\'t be obtained at reasonable cost in North America, I\'m going to reverse-engineer it so anyone can duplicate it - just as I did with the transit headsets a while back.
    \nI\'ve identified the plug that goes into the intercom as a 5-pin mini XLR, aka a Switchcraft TA5FL. Prices vary online, but Rugged Radios has them for under $6. The other end of the cable is the usual 1/8" 4-pole iPhone/iPod connector. The easy way to start would be with an iPhone cable for something else such as a $12 "microphone extension cable" and just replace the plug at the other end. You could also hook up another kind of phone if you know the wiring of the phone connection.
    \nThe Apple end works as such: the tip is the left audio out. The first ring is the right audio out, the second ring is the common/ground and the base ring is the microphone. On the Peltor end, the pins are numbered 1-5.
    \nPin 1: ground (second ring on Apple plug)
    \nPin 2: ground (second ring on Apple plug)
    \nPin 3: audio from phone (tip and first ring on Apple plug)
    \nPin 4: microphone (base on Apple plug)
    \nPin 5: microphone (base on Apple plug)
    \nHappy soldering!

    \r\n The RCA connections on the 110 (and 120 I think) can be used as an input too. They are a simple "tap in" to the audio circuit. Don\'t know if its a feature, or a "feature"...\r\n

    \r\n FMT110 Audio Out hack
    \n
    \nWas asked to make up an output for the FMT110 so that it can be used for an audio recorder. They have a 3.5mm stereo jack (wired using only one channel) as an input. I de-soldered and wired the existing jack to become a output by tying into the ears on the intercom (both headsets use the same signal on this model) Here is a PICTURE of the terminals to tie onto.
    \n
    \nThe output is a low dB out that requires an amp to make it useful for a true Line Out connection. A person can wire a simple OpAmp or single Transistor amplifier to do the job. Here is the finished amp I made up with adjustable gain and on/off switch.\r\n

    \nDoesn\'t really matter which is what. Short them together to talk (to the radio via the EXT) and open to not.
    \nThe EXT is always sending the mic (Pins 4,5). You don\'t actually NEED the PTT for the output. From what I found, when you close (short together) the PTT input on the Peltor, the output is blocked. I got one on my bench tonight and it is defiantly a N/O switch and it only has 1ohm or resistance so it is just a switch. I will have to do some further testing...

    Bryan,
    \n
    \nFollowing up on this since I\'m going to be building a circuit to send audio from my FMT120 to a GoPro HD Hero (and thanks for pointing out how cheap those had gotten, after I cancelled my helmet order, I couldn\'t resist).
    \n
    \nIs there any difference between pins 4 and 5? (i.e. audio from driver on one and co-driver on the other would be cool, but perhaps too much to ask?)
    \nAny idea why two common pins?
    \nAny idea what level the audio in allows for? From other sources I\'d guess it\'d take a headphone output.
    \n
    \n(I\'m planning on building a small box that allows me to turn on/off two GoPros at the same time, provides power to them so the battery won\'t be a limiting factor, and sends audio from the Peltor to one of them. Adding in a tiny mp3 player (and powering it off the same 5v as the GoPros) would be dead simple and nice on transits.\r\n

    As far as I can tell they are the same. I have not noticed any amplitude gain between them

    I dont know specifically but I attenuate the output of ham radios, but the output of a phone is good (no clipping)

    I have version 2 of my gopro remote in the car (used it at Ojibwe). You can easily power the gopro with a USB cable. Cant be done with the bus cable. The v2 I have in testing controls 2 cameras, an integrated amp for use with line level intercoms (peltor) and bypass for higher outputs like the terraphone. Internal and external selection of each camera. Here is the video of v1 if you missed it.

      Post Peltor Intercom meta thread

      This is an attempt to gather as much information on the peltor rally intercoms and headsets as possible into one place. It is intended to be a living document, and I encourage everyone to add in their information and links. I will add the information to this post as it is flushed out. Please point out any incorrect or incomplete information you see and add anything new you know.

      Intercom Models:

      FMT110 (discontinued, replaced by FMT120 ?)
      • Single volume
      • Switch to pad driver’s mic by -10dB
      • RCA mono audio-out.
      • 9V battery powered.
      • Optional FC15 – 12v power adapter.
      FMT120
      • Separate volume for driver and co-driver.
      • Switch to pad driver’s mic by -10dB.
      • RCA mono audio-out.
      • PTT button input
      • TA5F in/out connector for radio integration.
      • 9v battery powered.
      • LED Power indicator.
      • Optional FC16 – 12v power adapter.
      FMT200
      • Push button (vs. knob) controls
      • Separate volume for driver and co-driver
      • Separate settings for Stage and Road sections (Stage pads driver mic by 10dB, radio, phone and VOX are disabled).
      • VOX level controls
      • LED Power, level, VOX and mode indicators
      • 9V battery/12v vehicle dual-powered
      • RCA mono audio-out
      • DB-9 Radio interface
      • DB-9 GSM Phone interface (may work with others?)
      • There appear to be dual inputs for the headsets, one U-174/U and the other a TA5F

      Headset Models:
      • MT632 Open Face headset
      • MT63 Full-Face headset
      • MT3H6-02 Replacement set for G7/G77/G78 helmets
      • MT3H6-01 Replacement for G90 helmet
      • MT7H79A Practice headset


      Helmet Models (all BSI rated):
      • G7 – Open face Helmet with integrated headset (no longer made?)
      • G77 – Open face helmet with integrated headset (no longer made?)
      • G78 – Carbon-Fiber Open face helmet with integrated headset
      • G90 – Full Face helmet with integrated headset

      This has several ramifications. Some U.S. organizations do not recognize BSI (LeMONS - they do recognize an FIA standard, but it is not the one on my helmet, mine was made in 2006).

      CARS recognition of BS 6658-85 type A/FR is due to expire December 31, 2013. CARS follows FIA. NASA also usually follows FIA, but there is nothing in the 2011 NASA rules about the BSI spec expiring for CARS. I have seen no new BSI spec (if there even is one) Peltor helmets for sale.

      RA/RC is also silent of this (but seems less tied to FIA)...
      Other models are available for boating, with different certifications, etc, but are not applicable to rally in North America.
      Wiring:
      Common

      Headset Jacks (Nexus Plug):
      • Tip - Mic+
      • Tip Ring - Mic -
      • Sleeve Ring - Speaker+
      • Sleeve - Speaker-

      AUX Jack (RCA)
      • Shield - Ground
      • Center - Signal
      FMT120 Specific

      PTT (Nexus MP-101)
      1. ???
      2. ???
      Doesn't really matter which is what. Leave them open to pass audio through, short them to mute audio out. (thanks for the correction Bryan!)

      EXT (TA5F)
      1. ???
      2. ???
      3. ???
      4. ???
      5. ???

      FMT200 Specific

      TA5F headset connectors:
      1. Electret Microphone+
      2. Dynamic microphone+
      3. Microphone- (earth)
      4. Earphone-
      5. Earphone+


      Mobile phone "GSM" Connector:
      1. Microphone+ high
      2. Microphone- (earth)
      3. No connection
      4. Earth HT- if no bridge connection in the output stage
      5. HT- (SP-) if bridge connection is used in the output stage.
      6. Microphone+ low
      7. No connection
      8. Stage/Road
      9. HT+

      Radio Connector:
      1. Microphone+ high
      2. Microphone- (earth)
      3. Radio PTT
      4. Earth HT- if no bridge connection in the output stage
      5. HT- (SP-) if bridge connection is used in the output stage.
      6. Microphone+ low
      7. PTT
      8. Radio PTT
      9. HT+
      The PTT (Push to Talk)/Send button
      The Peltor FMT200 is equipped with a potential-free connection between pins 3 and 8 for the
      PTT function to be used with a com radio. A contact between pins 4 and 7 creates a connection
      between 3 and 8.

      Compatibility:
      • Terraphone - Peltor helmets can be used in Terraphone intercoms with an adaptor. Most (passive?) can only use one Peltor headset at once, while some (active adaptor) can use two. Terraphone headsets cannot (to the best of my knowledge) be used on Peltor intercoms due to the shared mic/speaker ground.
      • Terraphone Pro - Direct compatibility (?)
      • Stilo - ?
