OSDP (RS485)

The reader supports the Open Supervised Device Protocol (OSDP) [4] for connection to access control
systems. OSDP communicates over 2-wire RS485 and can therefore be used with long cables and does
not require extra cables for LED and buzzer control. The DIP switch S301:1-2 must be set to ON to enable
2-wire mode on the reader. In most cases S301:3-5 should also be set to ON to enable biasing and
termination. Input IN3 can be connected to a presence detector such as an inductive loop. Figure 22 shows
a typical connection diagram and the most common setting for DIP switch S301.

All OSDP settings are available under Settings.../Protocol Settings.../OSDP. For common access control
systems, OSDP can also be enabled using DIP switch S101 as described below.
