Prior to connecting the cable, remove preliminarily the electrostatic charge, e.g. by
touching a grounded piece of equipment (faucet, heater, etc.) with top of your palm.
•
It is recommended that the cable be first connected to the controller port.
Fig. 5. Connection of computer to the controller serial port.
If the D
LOAD
10 program fails to communicate with the computer after connection of the RS-
232 port, you should:
−
check that the option of programming by means of RS-232 port has been selected on the
controller DIP-switches;
−
check that the port through which the computer communicates with the controller has been
properly selected in the D
LOAD
10 program;
−
check that the cables connecting the computer with controller have been properly
connected.

ONNECTING THE
ACX-100
INPUT
&
OUTPUT EXPANSION MODULES
The ACU-100 controller communication bus can accept up to five ACX-100 input & output
expansion modules.
The modules can only be connected when the controller is
configured as a wireless device module interfacing with any alarm control panel.
The ACX-100 expansion modules should be connected to the controller bus in parallel. The
connection can be made with a typical unscreened cable, as used in the security systems
(e.g. DY8x0,5). When connecting the modules, remember to set the correct number of ACX-
100 modules connected to the controller on the controller DIP-switches. Lack of
communication with the module will be signaled on the TPR output as tamper.
Each module connected to the bus must have a different address set from the range 0 to 4.
These addresses must correspond to the number of a next module, as shown in Table 4. If
one ACX-100 module is connected to the controller, it must have address 0 set, if two, one of
them must have address 0 set, and the other address 1, etc.
The numeration of control inputs and outputs of the expansion module in the system depends
on the address set in it, i.e. on the module number. The numbers of control inputs and
outputs in consecutive expansion modules are shown in Table 4.
