2.1 Switches
The five configuration DIP switches located on the rear of the breakout panel are used for
selecting IBS/IDR modes of operation, and balanced or unbalanced signals, and control
of D&I looping.
The RS-422 multi-functional connector (J2) on the front panel may be used for standard
(non-overhead), IBS, or IDR (ESC) mode. SW1, SW2, and SW3 are used in selecting
IBS or IDR mode of operation.
SW4 and SW5 are used to select balanced or unbalanced inputs and outputs.
Refer to Table 2-1 for UB-530 configuration switch settings. The locations of the
switches are shown in Figure 2-1.
