Setting the address UCI reader protocol (RS485 bus operation, 2-wire)
The UCI reader protocol supports bus operation with up to 4 card readers. Each
reader on one bus must have a different “Bus Address” so that the system can dis-
tinguish between them. The Bus Address of a reader is set by DIP switches as
shown below in Figure 7 and Table 2.
