[HX-DU1006D User Manual] Harxon Corporation 4 1 Summary This manual is the installation and operating instructions of HX-DU1006D wireless data transceiver. HX-DU1006D is a universal wireless data transceiver module, adopted compact、modular plat-shaped structure, which is very suitable for designer-users to integrate RTUs、PLCs、banking automation equipments or similar devices. Figure 1 HX-DU1006D Data transceiver 1.1 Frequency Range HX-DU1006D operating frequency range is 410MHz~470MHz，frequency of transmitting and receiving can be set by programming. 1.2 Operating Mode Half-duplex mode is sending data for master transmitter input, receiving data if no input. When HX-DU1006D operates in half-duplex mode, emission will be started when data appears. Note: HX-DU1006D does not support duplex operating (Such as transmitting and receiving simultaneously). 1.3 Application Radio modem apply to point to multi-point and point to point and other applications, one point to multi-point (MAS) is the most common application of radio, which consists of a central master station and several related remote units, like figure 2. MAS network supply communication between a central host and remote terminal units (RTUs) or other data acquisition equipments. As to computer equipments, the radio operating is transparent, so, radio transmitting data as its original form, there is no change in the data format.
[HX-DU1006D User Manual] Harxon Corporation 5 Figure 2 MAS one point to multi-point network Point to point system In the case of licensed, HX-DU1006D can be configured as point to point system, which consists of two radios: one on the host, and the other on remote terminal units, detailed as figure 3. Data transmitting between two points of this system can set up simplex or half-duplex communication connection. Figure typically point to point connection 2 Installation design This radio has two connection ports: one is the board to board connector which supplies the data interface and DC power line; another is the 50ohm RF connector. To get a good connection, the RF connector and board to board connector should be applied some pressure. Figure 4 shows the external connection interface of radio modem.
[HX-DU1006D User Manual] Harxon Corporation 6 Figure 4 external connection interface All circuits of radio modem are masked in a shielded box, to reduce interference to nearby products. Transmitter can be set as transmitting 1W RF output power, so in order to reducing the RF interference to nearby electronic equipments, carefully choosing and designing the RF transmission path is very important. 2.1 Installation of Radio Figure 5 shown the installation dimension of data transceiver module, firmly fitted the radio modem onto the mounting surface of user system by holes on radio modem 4 corners (no fasteners supplied). Figure 5 Radio Modem installation dimension 2.2 Main Power Supply (3.3 Vdc) DC Power Supply HX-DU1006D can operate with any 3.3V power supply, which comes from data interface connector with good filtered. The power must supply 1.5A current at least and featured with current-limiting, even if you make radio modem operating on low power mode (0.5W).
[HX-DU1006D User Manual] Harxon Corporation 7 Note: HX-DU1006D only applies to negative grounding system; there is no fuse or reverse polarity protection on PCBA. Power supply positive must be provided by 23、 24、25、26、27、28 pin, data and power grounding should be connected to 1、5、7、9、19、20、21、22 and 30 pin. 2.3 Data Interface Connector Normally, data interface level is TTL; refer to figure 6 and Table 4, which is the detailed description of interface connector. Some pins of data interface connector use for factory testing, only connect the possible pins for using, improper connection may cause damage to the radio.

For final user, an EIA/RS-232 to TTL conversion circuit is needed to control the radio modem. Radio modem must be removed from user’s equipments or installed modules when configuration or diagnostics. Special tools can be used for setting the radio modem before final installation. Note: In order to entry configuration mode, the Config_EN pin (11 pin of data connector) should be set to “L” or GND. And in normal mode, this pin should be pulled up or floated. Table 4 listed every command entities and a simple functional description. Programming information is displayed in square brackets, command names followed. If you want to input a command, type the command first, and then press the button of “ENTER” As to programming command, pressing space button after commanding, and then pressing the corresponding information or parameter values, press “ENTER” button finally.
