3.2 DIP-switches
3.2.1 Controller connected to the INTEGRA / INTEGRA Plus control panel
The DIP-switches 1-5
are used for address setting. A numerical value is assigned to each
switch. In OFF position, the value is 0. Numerical values assigned to individual switches in
ON position are shown in Table 1. The sum of numerical values assigned to switches 1-5
means the address set on the device. The address must be different from that on the other
devices connected to the expander bus of the control panel.

Table 1.
When connecting the controller to the control panel to which the ABAX system
controller is already connected, it is recommended that a higher address be set in the
new controller than that in the controller already connected to the control panel.
3.2.2 Controller connected to the VERSA / VERSA Plus / VERSA IP control
panel
Set the switch 8 in ON position. The status of the other switches is irrelevant.
3.3 LED
The LED indicates the status of communication with the control panel:
ON – no communication with the control panel,
blinking – communication with the control panel OK.
