1, 2, 3... 1.
In systems which use only the insulated C500-LK203 Host Link Units, connect
the frame ground to the shield wire at the connections to the Host Link Units and
at either end of the connections between Link Adapters. In systems using the
insulated C500-LK203 with other types of Host Link Units, connect the frame
ground to the shield wire at connections to the C500-LK203 Host Link Units and
at both ends of all connections between Link Adapters and between the other
Host Link Units and Link Adapters.
When connecting a multiple-link system with RS-422 cable, use shielded
twisted pair cables for the Host Link Unit. The total cable length of the entire sys-
tem must not exceed 500 m. The length of each branch line should be kept to
less than 10 m.
The optical Host Link Units can be used to achieve greater distances in the over-
all system (see Example 2 in 1-2 System Configuration). If they are connected in
series, however, signals are not transmitted to any Unit that is not supplied with
power, or any other Units beyond it. To avoid any problems with this, signals can
also be distributed through Link Adapter 3G2A9-AL002-PE. To connect the Host
Link Units to the host computer, Link Adapter 3G2A9-AL004-(P)E is necessary
to be able to interface the optical fiber cables and the RS-232C and RS-422
cables.
The following procedures should be followed when wiring RS-232C and RS-422
connectors.
The procedures listed below correspond to the following diagrams.

Cut the cable to the required length.
Use a razor blade to cut away the sheath (being careful not to damage the
braiding underneath): 25 mm for RS-422 cable; 40 mm for RS-232C cable.
Use scissors to cut away all but 10 mm of the exposed braiding.
Use wire strippers to remove the insulation from the last 5 mm of each wire.
Move the boot to cut the edge of the sheath and fold the braiding back over
the end of it.
Wrap aluminum foil tape over the top of the braiding on top of the boot for
one and a half turns.
