2.0 POWER SUPPLY
Before powering the unit, check that the MAINS VOLTAGE SELECTOR is set to the position
of the power supply available in your country.
You can choose between 115Vac and 230Vac.
WARNING
All maintenance operations must be carried out by
qualified
personnel only who must be informed of the risks of
electric shock.
Do not open the cover of the unit
without first of all pulling out the power cable.
For European countries, the TZM1612 must be powered at 230
Vac 50Hz using the cable provided.
The plug of the cable must be inserted in the related panel plug
to the left on the back of the unit.
In some countries, regardless of the voltage available, the plug of the cable must be
replaced to adapt it to local standards. The wires are coded as follows:
- Brown PHASE (Identified with the letter L, may be red)
- Blue NEUTRAL (Identified with the letter N, may be black)
- Yellow/Green GROUND (Identified with the letter E, may be green)
WARNING
A ground connection is compulsory
The MAINS VOLTAGE SELECTOR is factory-set to 230Vac.
7.14 SET RS485 COMMUNICATION PARAMETERS
The host must send the following sequence:
CASR
followed
by
CR
where:
C is the character Hex 43
A is the address of the matrix (from 0 to 7)
S is the TX/Rx speed (1 or 2)
1 = 2400 bit/sec
2 = 9600 bit/sec
R is the reply time (from 1 to 7) in multiples of 16 msec.
1 = 16 msec
2 = 32 msec
3 = 48 msec
4 = 64 msec
5 = 80 msec
6 = 96 msec
7 = 112 msec
The TZM1612 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
Example: to program the TZM1612 connected as unit with address 4, Tx speed of 2400
bit/sec and a reply time of 80 milliseconds, the following characters must be sent on line:
43 34 31 35 0D
8.0 CONTROL USING COMPUTER via RS485
On its site
www.elprovideolabs.com
, Elpro has made available software running under
Windows suitable for controlling the TZM1612 via RS232 or RS485.
If the user intends to develop personalized software, the protocols to be implemented both
RS232 and RS485 are available on the same site.
All functions of the TZM1612 can be controlled through transmission/reception by a
computer of strings of hexadecimal and ASCII characters.
The transmission protocol is of the master/slave multi-point type where the TZM1612 are the
slaves while the host that controls these is the master. Up to 8 TZM1612, identified by
addresses form 0 to 7 can be connected on the 485 bus.
The characteristics of the serial connection are:
8 data bits, no parity, 1 stop bit and speed settable to 2400 or 9600 baud
The transmission speed, the address of the unit and the reply time can be set with a suitable
command from RS232.
The reply time of the TZM1612 is the time that must pass between end of reception of the
command and the start of transmission of the reply.
This time allows the host to release the 485 bus and to prepare to receive without casing
conflicts.
The default parameters are as follows: - speed
= 9600 bit/sec
- unit address
= 0 (30 hex)
- reply time
= 32 ms4
