2.0 POWER SUPPLY
The TZ09 must be powered at 230 Vac 50Hz using the cable provided.
The cable must be terminated in the related panel plug on the left at the back of
the unit.
The panel plug is complete with fuse-holder for 5X20 fuses.
If the fuse blows, replace with a fuse
with the same rating
as specified on the
back of the unit (T 500mA).
WARNING
All operations must be carried out by qualified personnel only
who must be informed of the risks of electric shock.
In some countries, the power plug must be adapted to local standards.
The wires are identified according to the following coding:
- 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 mandatory
.
7.15 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.

The TZ09 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 TZ09 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 TZ09 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 TZ09 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 TZ09 are the
slaves while the host that controls these is the master. Up to 8 TZ09, 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 TZ09 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 ms
