TZM443
8.0 CONTROL FROM COMPUTER VIA RS485
A software in Windows, available on Elpro's website www.elprovideolabs.com, is able to
control the TZM443 via RS232 or RS485
If the user wants to develop his own customized software, the same website offers
protocols to be implemented both for RS232 and RS485.
All functions of the TZM443 matrix can be controlled by sending or receiving hexadecimal
or ASCII character strings via a computer.
The transmission protocol is of the multipoint master/slave type: the TZM443s are the
slave machines, whereas the host which controls them is the master machine.
Up to 8 TZM443 units, identified by addresses 0 – 7, can be connected to the 485 Bus.
The serial connection features are:
The transmission speed, the address of the unit and the response time can be set via a
special control from the RS232.
The TZM443 response time is the time that should pass between the end of the reception
of the command and the beginning of the transmission of the response.
Such time allows the host to release the 485 bus and to get ready for the reception
without causing conflicts.
the following parameter defaults are automatically applied:
