Introduction
E232 is a RS-232 to E1 converter which could implement bidirectional conversion between RS-232 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. E232 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.
Features
- Support 1 RS-232 serial port and 1 E1 port
- Support signal indication of E1 port data, E1 port loss of synchronism and upstream alarm
- Support optional clock: internal clock, external clock, recovery receiving clock
- Support E1 port loopback and RS-232 loopback
- Two optional power supplies: 220VAC or -48VDC
- Support -25～70℃ wide operating temperature range
