RS-485 to E1 converter

THÔNG TIN SẢN PHẨM

E485 is a RS-485/422 to E1 converter which could implement bidirectional conversion between RS-485/422 serial port and E1 digital port. It adopts desktop mounting to meet the requirements of different scenes.

The data port of this device is operating at a rate of unframed 2.048Mbps of E1. User data has accounted for all 32 timeslots of E1 frame. The main E1 link could provide 3 types of clock source: E1 port recovery clock, internal clock and external clock of digital port. E485 provides loopback and phase adjustment function, which is convenient for digital port testing.

DIP switch could implement functions like impedance setting, BNC grounding setting, clock setting, loopback setting, restoring to factory setting, etc. Hardware adopts fanless, low power consumption, wide temperature range design, and can be widely used in various departments and systems such as industrial control, environment monitoring, network monitoring, etc.
