The HJ-ICR08DE/F dual E1/dual optical port series is our independently researched and produced chain protocol converter. It achieves physical layer conversion between E1 interfaces and standard RS232/422/485 interfaces, providing secure and seamless connections for communication between devices with different interfaces in a network. It offers 1 to 8 asynchronous RS232/422/485 data interfaces. The chain protocol converter is divided into master station and node station. If any node station equipment is powered off or fails, it does not affect the transmission of the main chain. The dual E1 transmission interface can achieve 1+1 protected transmission, suitable for high-demand scenarios.

This series boasts stable performance, comprehensive features, low power consumption, high integration, and compact size.

Feature Highlights:

1. Achieve 1 to 8 channels of RS232/422/485 asynchronous data.

2. Point-to-point transmission equipment for E1/Fiber optic interface 1+1 protection.

3. All interface technical parameters comply with international or domestic relevant standards.

4. Features surge and three-level lightning protection.

5. Features an E1 interface bypass function, ensuring that a failure at one node does not affect the transmission of signals to other nodes.

6. Standard Baud Rate: ≤115,200 bps

7. Transmission Interface: E1 (dual E1 interfaces for node stations).
