What is the RS232 to E1 protocol converter

Time : Oct. 18, 2022    View : 36

The RS232-E1 protocol converter is a high-performance product independently developed and produced by our company. It converts transparent E1 into an interface conversion device of V.35 or RS232 asynchronous data interface. The V.35 interface of this device can be connected to DCE or DTE. For devices with two working modes, the RS232 interface only supports asynchronous RS232 data, and the maximum asynchronous rate that can be supported is 115200bit/s. Next, I will introduce the RS232-E1 protocol converter products in detail.

It converts transparent E1 to an interface conversion device of RS232 asynchronous data interface.

1. Product Overview

DA-2000E1/V.35/RS232 conversion equipment is a high-performance product independently developed and produced by our company. It converts transparent E1 into interface conversion equipment of V.35 or RS232 asynchronous data interface. The V.35 interface of this equipment can be connected to For devices with DCE or DTE working modes, the RS232 interface only supports asynchronous RS232 data, and the maximum asynchronous rate that can be supported is 115200bit/s.

This equipment can provide centralized equipment, each frame provides 15 slots, all of which can be used to insert equipment cards. The centralized equipment can be mixed with a variety of equipment insert cards: DA-2000K (E1/V. DA2010K (E1/10Base-T) and optical transceiver cards include DA30K, DA30VK, DA30EK, etc. All these devices can be mixed.

 

2. Main Features

③ When the E1 interface is 75Ω, it is a BNC connector, and when it is 120Ω, it is an RJ-45 connector, which is set internally;

④ The device can work in framing mode or 2M transparent modes;

⑤ Provide 1 channel V.35 or RS232 interface;

⑥ The V.35 interface can be connected to DCE or DTE equipment, and the RS232 interface is in the DCE working mode;

⑦ Provide three clock modes: master clock, slave clock, and external clock;

⑧ With perfect alarm and status indication function;

⑨ Adapt to a variety of power supply environments – 48VDC/220VAC.
