KB3072 Zigbee Data Terminal Unit

1. KB3072 ZTU Brief Introduction

KB3072 ZTU (Zigbee Data Terminal Unit) is enhanced Zigbee module that using high-reliability 8051 CPU core and IEEE 802.15.4 compatible wireless transceiver. Compared with similar products, it transmission distance father, anti-jamming capability stronger and more flexible networking.

Based on the Zigbee network of data transmission is stable, reliable and data relay, KB3072 ZTU combined with KB3030, has been widely used in the field of unattended, remote equipment monitoring, remote data acquisition, remote meter reading and remote scheduling. Due to this product is designed for industry integrated, we adopt special designs in the temperature scope, shaking, EMC and interface multiform and so on, to keep it good stability in the severe atmosphere, ensure high quality for your device.
KB3072 ZTU applicable to point-to-point, multi-point-to-point, point-to-multipoint and multipoint-to-multipoint data transparent transmits. It’s widely used in electric power automatic system, industry monitoring, traffic management, atmosphere, pro-environment, pipe network monitoring, finance, securities departments and so on.

2. KB3072 ZTU Feature

  • Standard industrial products, EMC anti-jamming design, strong adaptiveness.
  •  Independent research and development, the use of the classic 8051 kernel, mature, stable.
  • Embedded Watchdog chip, provide multiple Reset mechanism, can be controlled by software, achieve industrial security mechanism perfectly.
  • Work frequency 2.4GHz, transmit stable and reliable.
  • Advanced and strict data communication protocol, with the function of correction and encryption. Never lose package when data transmission, can achieve pictures over than 100K and Flash animation files transmission, no Mosaic happened.
  • Powerful, supporting three node types: central node, the relay route and terminal.
  • Support three transmission modes: broadcast, master-slave, point-to-point;
  • Support variety of Auto networking: point-to-point, multipoint-to-point, point-to-multipoint, multipoint-to-multipoint; combined with our other product, you can set up a large cross-regional system network;
  • Low power consumption: just two AA batteries can be driven;
  • Remote modify ZTU parameters: Support remote modify the parameters, after the product install, if you need to adjust the parameters, simply use software control terminal remote configuration the parameters;
  • Support the serial port baud rate: 1200 bps to 115200 bps, support 7, 8 data bits, one stop bit, odd parity, even parity, no parity;
  • Working temperature range: -40℃-80℃, communication is not effected at -40℃.

3. Safe Use

KB3072 ZTU Completely complied with national radio product safety technical regulations.
Warm Tip: You must not touch the antenna with your hands or body. After KB3030-N DTU started, Please keep away from the antenna. If the antenna is damaged, you must replace it in time, assorted and qualified cable and antenna.

4. EMI

Now most electric device all has electromagnetic pulse hardening, but some old device may have no, under RF power radiation, it may go wrong. When you use KB3030-N GPRS DTU, please check the device nearby have electromagnetic pulse hardening or not. 

5. Appearance and Interface

KB3072 ZTU has two physical interfaces:
. The first is 10 pins main interface: RS232/RS485/TTL (5V)/CMOS (3.3V), Power supply, Modem COM port
. The second is SMA RF interface: For the antenna
. Size: 82 mm (L) * 59 mm (W) * 25.2 mm (H)
