■ Specifications

*1 For RS485 converter on the computer side, we recommend SI-35 and SI-35USB (from LINE EYE Co.,Ltd.). When using

SI-35, SI-35USB or PLC from our company (which can be connected up to 99 units), up to 99 can be connected. In case

using this system with the other devices, up to 31 can be connected.

*2 Please check with the actual devices when some commercial devices with RS485 interface are connected. The number of

connected devices, transmission distance, and transmission speed may be different according to using transmission line.

*Ethernet is the trademark of Xerox of USA.

*This product has the software developed by OpenSSL Project in order to use

OpenSSL Toolkit. (http://www.openssl.org/)

*1 It changes the transmission speed automatically with auto-negotiation function.
