6.0 Functions with IR remote control
7.0 Computer control via RS232
8.0 Computer control via RS485
When installing the TZM 1612 unit, please read this handbook carefully.
The manufacturer shall not be held responsible for damage due to use, even
correct, of its products.
The data and characteristics of the product may be modified without prior notice.
According to the protocol used, the messages exchanged between the host and TZM1612
are amongst the following control characters:
- command from host to TZM1612:
STX ADDR
command
ETX
- reply of the TZM1612 to the host:
STX ADDR
reply
ETX
The character
STX
corresponds to 02 hex,
the character
ETX
corresponds to 03 hex,
the
ADDR
field is the address of the TZM1612: from 30 hex to 37 hex (or from 0 to 7 in ASCII)
The contents of the
command
and
reply
fields are the same as the commands indicated
above for the RS232 protocol except for the
CR
character
(hex 0D) which is omitted in this
case.
8.1 COMMANDS MANAGED
The commands that can be sent via RS485 are all those envisaged for RS232 except for the
"Set RS485 communication parameters" command:
- video and audio switching command
- video switching command
- audio switching command
- status request
- creation of a preset
- recall of a preset
- firmware release identification request.
- global status request
- set switching through blank time
- switching through blank time request
Example: in this case the format of the video switching command will be as follows:
STX
ADDR
VXXYY ETX
where: V is the character Hex 56
XX is the output (from 01 to 12)
YY is the video input (from 01 to 16)
The TZM1612 matrix replies:
STX ADDR ACK
ETX
where: ACK is the character Hex 06
if the command has been performed correctly
STX ADDR NACK
ETX
where NAK is the character Hex 15
if transmission errors have been detected or incorrect parameters.
Therefore, the switching command of video input 5 to bus 4 for the TZM1612 with address 2
will be as follows:
STX
2 V 04 05
ETX
(in Hex code: 02 32 56 30 34 30 35 03)
the matrix will reply with:
STX
2 ACK
ETX
(in Hex code: 02 32 06 03)
or with:
STX
2 NACK
ETX
(in Hex code: 02 32 15 03)
