This cable pinout is for the 800 trunked Smartnet Mostar, or ATM Mostar that has an STX controller. That cable uses a standard RIB and uses standalone Smartnet field programmer software (RSS).
For conventional VHF/UHF Mostars, a MIB and its own software (Ver:AA.00.00.00) will program all vintages of radios, including NVR (all non-display) and Display (also includes some late model non-display).
The R1801 only worked on early vintage radios (don't know how to tell the cutoff).
There has been no information of what radios the Epson setup programs.
Also, conventional Mostars won't take splinter channels and the MIB and RSS are NLA from Motorola.
