RB-USB RIM Lite

*The V2 adds connectivity from the PC_OK indicator to pin 7 of the radio connector. Pin 7 goes Low when the PC and Interface are communicating successfully.
 
This is a streamlined version for folks that don't require all of the features that the "full-blown" RIM has to offer.

• Instead of two channels of low-pass filtering, the RIM lite only has one. Typically only one channel of filtering is needed since there is only ONE modulator in a given radio. This filter remains 5 pole with a "knee" of approximately 10kHz.
• The charge pump and additional amplification stages have been removed to reduce cost. This module still makes over 1Vp-p of audio which is adequate for driving most modulator circuitry directly.
• The buffering of the COS and CTCSS inputs has been reduced to a simple diode. Again reducing circuitry that is not often used.
• The discriminator audio input attenuator is now a potentiometer. No more external voltage dividers necessary to knock the radio's audio down to the CM119's input level!!
• The DB-25 connector has been replaced with a DE-9. This simplifies connections and reduces product size. However, this means that the additional I/O pins are not brought to the outside world.
