The scanner is connected to other devices on the RIO link in a daisy
chain (serial) configuration. There are no restrictions governing the
space between each device, provided the maximum cable distance
(Belden 9463) is not exceeded.
A 1/2 watt terminating resistor (included with the module) must be
attached across line 1 and line 2 of the connectors at each end
(scanner and last physical device) of the RIO link. The value of the
resistor depends on the baud rate and extended node capability, as
shown in the table that follows.
Important:
To use extended node, all devices on the RIO link must
support it. Refer to each device's user manual.
