A 1:1 PC Link is possible only with the SRM1-C02-V1/V2 PCs, which are
equipped with an RS-232C port.
Only the 16 LR words from LR 00 to LR 15 can be linked in the SRM1, so use only
those 16 words in the CQM1 or C200HS when making a 1:1 PC Link with one of
those PCs. A 1:1 PC Link cannot be made to an SRM1 PC using LR 16 through
LR 63 in the CQM1 or C200HS.
Refer to the SRM1 Master Control Units Operation Manual for information on
cable connections in a 1:1 PC Link.
When an SRM1(-V2) is used in a 1:1 PC Link, make the following PC Setup set-
tings from a Programming Device.

2. For information on the 1:1 PC Link settings for another OMRON PC, refer to
that PC's Operation Manual.
