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 bot
h ends of the daisy chain. If it is installed in the middle of the chain, the performance in communicating will deterior
ate because it reduces the signal level. If the termination resistor of BioEntry Plus is required, set the #1 DIP switch
to ON.
•
Up to 32 devices can be connected via daisy chain (1 master device and 31 other devices).
