Tait TM8100 Protocol Manual

12 CCDI TM8100/TM8200 Computer-Controlled Data Interface (CCDI) Protocol Manual
© Tait Electronics Limited April 2007
1.1 Compatibility
This manual describes CCDI version 3.00 and later.
The radio programming application used should be the latest released
version for both the TM8100 and TM8200 radios. Refer to the
Ta itWo r ld we b s i te http://www.taitworld.com for the latest versions of
programming application.
1.2 Serial Ports
Three ports are available for CCDI asynchronous serial communication
with the radio. The microphone and auxiliary ports are accessed externally,
and the internal options connector is internal to the radio.
Only one of these ports can be used for CCDI transmission and reception
at any time. The port is selected in the Data form of the programming
application, Serial Communications tab. Select “Mic”, “Aux” or “Internal
Connector”.
■ Mic: The radio will transmit and receive data via the MIC_TXD and
MIC_RXD lines on the microphone connector.
■ Aux: The radio will transmit and receive data via the AUX_TXD and
AUX_RXD lines on the auxiliary connector.
■ Internal Connector: The radio will transmit and receive data via the
IOP_TXD and IOP_RXD lines on the internal options connector.
This connector is used to fit an internal options board into the radio.
For more information on these connectors, refer to the service manual.
