The Frame control interface uses RS422.
A full duplex 5 wire balanced communications standard that allows
communications to be multi-dropped to more than one Frame.
Since PC’s only come with RS232 ports a
small converter is required
to
convert the
RS232
signals to RS422.
If you purchased
any of the SmartControl software options you will
have received a suitable converter and cable.
In the event
that you wish to purchase your
own converter and/or make your own comms cable please see Appendix
A at the rear of this
document for more
information.
