Connection Details for I/O Expansion (XT91/XP91 Modules) on Local
Extension Bus
Figure 7 displays the connection details for XT/XP modules on a local
extension bus.
Figure 7: Connection Details for the XT/XP Module
Consider the following information when you work with the
connections details for the XT91/XP91 Modules:
• Maximum XT modules are 4 x XT91D00 (or XT-9100).
• Maximum bus length is 1200 m (4000 ft).
• You must set appropriate N2 bus serial address on each XT module.
• Install a repeater (for example, RP-9100-810x) to regenerate the
RS-485 signal. You install the repeater in case more than
31 N2 devices are connected on the local link extension bus and/or
the local link extension bus length is more than 1,200 m (4,000 ft).
• Install 220-ohm end-of-line resistors at each end of the XT-Bus line
when the bus length is greater than 100 m (330 ft). When the bus
length is less than 100 m (330 ft), insert only one 220 ohm resistor
at the FX16 Master Controller end only.
