Note 1) Max. transmission distance between CUnet I/O module and HUB module, HUB module and HUB module is as follows.
100 m at 12 Mbps, 200 m at 6 Mbps and 300 m at 3 Mbps.
Note 2) Be sure to connect CU0A/CU0B to the host side.
Note 3) The terminating resistor must be enabled for the modules at both end of the communication line. The terminating resistor is
incorporated in the feeder side port of the HUB module.
MOUNTING REQUIREMENTS

CONFIGURATIONS
• The configurations such as communication mode and
transfer rate must be same for all modules connected to
the communication line.
• The terminating resistor must be enabled for the mod-
ules at both end of the communication line. The termi-
nating resistors of the modules other than them must be
disabled. (The terminating resistor is incorporated in the
feeder side port of the JC-CU as it is end of the commu-
nication line.)
• In order to use the hub module, it is required to set frame
option at any CUnet I/O module connected to network.
For detailed information about settings refer to the man-
ual of your CUnet I/O module.
