• Connect the Ethernet cable to a host device (e.g., Switching Hub or PLC) that supports STP and
ground the host device to a ground resistance of 100 Ω or less.
Usage
• The communications range depends on the operating and installation environment. Use the
Reader/Writer only after sufficiently testing operation onsite.
• If multiple Reader/Writers are installed near each other, communications distances may decrease
due to mutual interference. Refer to A-5 Mutual Interference of Reader/Writers (Reference Only) on
page A-10 and check to make sure there is no mutual interference between Reader/Writers.
Errors and Failures
