SATEL
5 –
RS-232 port (TTL standard)
for connection of the computer (the connection can be
made by using the cables included in the set manufactured by the SATEL and
designated DB9FC/RJ-KPL). The port enables updating of the module firmware.
6 –
package of DIP-switches
intended for setting an individual address of the module (see
section
DIP-
SWITCHES
).
7 –
red color LED
indicating as follows:
−
blinking light – data being exchanged with the control panel;
−
steady light – no communication with the control panel.

1.1 DIP-switches
The DIP-switches from 1 to 5 are to be used for address setting. The address must be
different from that of the other modules connected to the communication bus of alarm control
panel. In order to determine the expander address, add up the values set on individual
switches as shown in Table 1.

2. Installation and start-up
Disconnect power supply before making any electrical connections.
The INT-RX expansion module electronics board includes some static sensitive
components which should be discharged before installation. Avoid touching
the onboard components during installation.
The INT-RX expansion module is designed for indoor installation in spaces with normal
humidity of air. When selecting the place of mounting, take into consideration that thick
masonry walls, metal partitions, etc. reduce the range of radio signal. It is recommended that
the module be installed at a high point, so as to achieve a better radio communication range
