Introduction
The Computer Controlled Data Interface (CCDI) protocol is a Tait
proprietary command protocol embedded in the TM8100 and used for
communicating with the TM8100 via asynchronous serial ports.
The TM8100 is the DCE (Data Circuit-Terminating Equipment) and is
connected directly to the DTE (Data Terminal Equipment), usually a PC,
via the serial port.
Two modes of operation are available using the serial ports:
■
Command mode
■
Transparent mode

When in Command mode, commands and response messages are passed
between the PC and the TM8100 using the CCDI protocol. The
Command mode baud rate is selectable using the TM8000 Programming
Application to either 1200, 2400, 4800, 9600, 14400 or 19200 baud.
When in Transparent mode, communication between the PC and the
TM8100 is Fixed Frequency Shift Keying (FFSK) data and is selectable using
the TM8000 Programming Application to either 1200, 2400, 4800, 9600,
14400 or 19200 baud.
The over-air data rate is always fixed at 1200 bps for FFSK data.
CCDI2 refers to CCDI version 2.XX.
