Extension Cable - Celco Spider67 System Manual

2.3 Extension cable

Spider67 extension cable is used between gateways and I/O modules. The overall
cable length from the extension interface to the last module is less than 100m .
P01 series cable is the standard extension cable. P09 series long distance
communication cable is recommended if the extension distance is over 10m or
high load current, P03 series flexible communication cable is especially used for
bending lifespan like drag chain (see 1.4)
Terminal resistance is recommended to eliminate reflection and echo, which are
used to prevent discontinuous extensible cable resistance or interference caused
by long distance communication. As Spider67 is installed terminal resistance,
users need to connect a resistance to Out of the last module of each extension
interface.
