Overview

This series of products HT308RI-2R-2SFPG using industrial rail design, each device has two fiber-optic ports for ring network to achieve in a harsh environment, the stability of data transmission, reliability and timeliness. Work network signal into a chain structure, but simplifies installation and reduces the cost of the project.

This product HT308RI-2R-2SFPG offers: two Gigabit SFP optical ports; eight electrical Fast Ethernet interfaces, 2* RS232 / 422/485 serial port. 2 serial ports is individually designed, each serial port-based design, one is the master control node, the other all slave nodes。
