1.
It is important to note that the aggregate load of each pair of RS-485 and Wiegand connections together must not exceed
750mA. Each set of RS-485 and Wiegand can support 750mA.
2.
Check wire lengths to verify that voltage drops are acceptable. Calculations are based on a single RM-4 reader with key-
pad and LCD (250mA). Using 22AWG, distance = 600ft. (.0165 ohms/ft.). Using 18AWG, distance = 1500ft. (.0065 ohms/
ft.).
For more information regarding other inputs available and details of configuration, refer to the
I/8 -CSI User Guide.
