Only DL/T645-2007 is supported.*2 For RS485 converter on the computer side, we recommend SI-35 and SI-35USB (from LINE EYECo.,Ltd.). When using SI-35,SI-35USB or PLC from our company (which can be connected up to 99units), up to 99 can be connected. In case using this system with the other devices, up to 31 can beconnected.*3 Please check with the actual devices when some commercial devices with RS485 interface areconnected. The number of connected devices, transmission distance, and transmission speed maybe different according to using transmission line.< USB >Electric specification Conform to USB2.0 standardConnector shape USB series MiniBInsulation method Insulated to internal circuitTransmission speed 12Mbps(Full‐Speed)Transmission function Computer link (MEWTOCOL)*Install the dedicated USB driver before using USB port.*Do not ground the signal wire of USB communication.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
