The DJHW/HZ-33-100S-C product is a dual transmitter and dual receiver device with a transmission power of 2 * 2W, supporting point to multipoint and decentralized self-organizing network for broadband data transmission.
DJHW/HZ-33-100S-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 OFDM (Orthogonal Frequency Division Multiplexing) key technology. It supports multiple bandwidth allocation (1.4MHz, 3MHz, 5MHz, 10MHz, 20MHz) flat system architecture designs, 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. Under a bandwidth of 20MHz, the maximum data volume supports 100Mbps.
Support broadband transmission such as star networking and mesh networking;
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 33dBm;
Supports channel bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, and 20MHz.
Instructions for Use:
The DJHW/HZ-33-100S-C product requires a power supply of 12V 1.5A or higher. 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-33-100S-C product has a maximum rated transmission power of 33dBm.
Bandwidth configuration:
The DJHW/HZ-33-100S-C product supports channel bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, and 20MHz.
Transmission distance:
The DJHW/HZ-33-100S-C product supports a transmission distance of 50KM (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.
(DJHW/HZ-33-100S-C Product Physical)
(DJHW/HZ-33-100S-C product indicator light)
The indicator lights of DJHW/HZ-33-100S-C products are as follows from the left:
When the PWR light is on, it indicates that the device has been powered on
Master slave indicator light MODE (red green dual color) (TBD)
MIN0 mode, red light always on
CA mode, green light is always on
Non CA and non MINO, the blue light is always on
LAN port lights LAN1 and 2 (green)
When there is data transmission and reception at the port: the port light flashes.
Received signal energy light (RSSI 3 green lights) (reserved function)
The more energy lights are on, the better the signal reception quality.
