Suprema Xpass S2 [13/19] Connecting to secure i o 2

Installation

Connecting to Secure I/O 2

Refer to the following figure for connecting.

• RS-485 should be AWG24, twisted pair, and maximum length is 1.2 km.

• Connect a termination resistor (120Ω) to both ends of a RS-485 daisy chain connection. It should be installed at both ends

of the daisy chain. If it is installed in the middle of the chain, the performance in communicating will deteriorate because it

reduces the signal level.

• Up to 32 devices can be connected via daisy chain (1 master device and 31 other devices).
