Command 0F with FNC 95 and command 06 as described in Appendix B
are the only commands supported by the Smart Transmitter Interface.

Consult the Data Highway/Data Highway Plus/DH-485 Protocol and
Command Set Manual for the additional information required to
successfully implement both full and half duplex communications with the
Smart Transmitter Interface.

The Smart Transmitter Interface supports one Data Highway Plus host
using the pass-through functionality supported by some Allen-Bradley
programmable controllers. This host requires using proprietary
Allen-Bradley Interchange Software. For further information on using the
Smart Transmitter Interface with such a host, you should contact your
Allen-Bradley representative.
