The following diagram shows a 1:1 connection of a host computer and a Host
Link Unit (C200H-LK202-V1, 3G2A5-LK201-EV1, C500-LK203, or 3G2A6-
LK202-EV1).
back of the Host Link Unit is set to 0 V.
Set the I/O port switch on the back of 3G2A5-LK201-EV1/C500-LK203 Host
Link Units to “RS-232C.”
Set to 0 V when the CTS (Clear-To-Send) signal will usually be ON. Set to Exter-
