SB9600

Information on the SB9600 Bus from Motorola.

The bus operates in two modes:

1. SB9600

   this mode uses small (5 byte) commands and is used to control/test the radio and interface with control heads and radio decks

2. SBEP - Serial Bus Expanded Protocol

   SBEP is an addition to the SB9600 serial bus protocol that will be used to achieve high data transfer rates between options on the SB9600 bus or between an external computer and the main processor of the radio or it’s options.
