DJHW/HZ-40-100S-C is a dual transmitter and dual receiver 2 * 10W transmission power, low-power self-organizing network integrated device. This device supports point-to-point and point to multipoint networking.
DJHW/HZ-40-100S-C adopts OFDM TDD bidirectional wireless communication technology, which has strong anti-interference and penetration capabilities, achieving stable wireless data transmission.
This product is suitable for fire protection, inspection, monitoring and other scenarios. This product is based on the LTE wireless communication standard and adopts the key technology of OFDM (Orthogonal Frequency Division Multiplexing). It supports multiple bandwidth allocations (1.4MHz, 3MHz, 5MHz, 10MHz, 20MHz) and has a flat system architecture design, effectively reducing system latency and improving system transmission capacity. It has the characteristics of long transmission distance, large data throughput, and strong anti-interference ability. All communication between the slave node and the central node shares the working bandwidth in one direction, with concurrent uplink and downlink at a bandwidth of 20MHz, and supports a maximum data volume of 100Mbps.
Support broadband transmission such as point-to-point and point to multipoint;
Supports multiple data interfaces including TTL, RS232, RS485, and CAN;
Supports high bandwidth, with a maximum payload of 100Mbps;
Support automatic frequency hopping function, which can automatically find the best frequency point in the current wireless environment;
Supports transmission power up to 40dBm;
Supports channel bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, and 20MHz.
Instructions for Use:
DJHW/HZ-40-100S-C product power supply needs 24V@3A Before starting up, check if the antenna and connecting wires are properly connected. The main antenna (antenna identification MAIN) must be connected to the antenna, and the secondary antenna (antenna identification AUX) is not necessary. Not connecting the antenna will affect transmission stability.
Please be sure to install the antenna before powering on to avoid damaging the circuit. The distance between the two antennas should be greater than 15cm, and the antenna should be kept away from large metal structures as much as possible to avoid communication obstruction due to the above reasons.
Automatic power control:
The DJHW/HZ-40-100S-C product has a maximum rated transmission power of 40dBm.
Bandwidth configuration:
The DJHW/HZ-40-100S-C product supports channel bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, and 20MHz.
Transmission distance:
The DJHW/HZ-40-100S-C product supports a transmission distance of 48KM (optional: choose the appropriate version according to the actual application scenario).
*The application scenario refers to the situation where the master and slave devices are fully connected and there is no same frequency interference.
