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.

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
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
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.

3 Radio Modem Configuration and diagnostic commands
Radio modem configuration and diagnostics achieved by data interface
connector, commands are controlled by PC or a dedicated terminal equipment. 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.

3.1 Errors Messages
Errors Messages may occur in the processing of terminal interface listed as
below:
UNKNOWN COMMAND—unrecognized command. Please refer to the command
description in the command using information.
INCORRECT ENTRY—command format or parameter values are incorrect. Please
refer to the command description in the command using information.
ACCESS DENIED—command can’t be completed successfully, this command may
be allowed by final user.
3.2 Initialize Configuration
Some basic setting steps of radio configuring into user’s products as below, in
most cases, these steps are sufficient to complete the installation. These steps assume
that radio modem is already installed into user’s system or product, also connected the
data interface and antenna interface well.
1、The radio modem is installed into user’s system or product, and connect data interface and
antenna interface well;
2、Connected to a terminal radio modem via interface of user’s product (serial setting:
asynchronous@ 38400 W/8N1);
3、Enable radio modem configuration mode (pin 11 of radio modem data interface grounding);
4、Checking the configuration parameter of radio modem via serial terminal command (refer to
command set);
5、Checking and setting RF transmitting and receiving frequencies;
6、Checking and confirming the communication protocol type.
Note:
Operating frequency always is not be set when in factory, users need to set the possible
transmitting and receiving frequency via serial command, but the radio modem must be
programmed according to the operating frequency licensed by users.

8、Disconnect pin 11 of data interface to ground;
9、Connect the data interfaces of data equipment and radio modem for testing.
4 Troubleshooting
Doing some simple checks in advance is a good habit, under normal operating
conditions; the radio modems must meet the basic requirements as below:
• Appropriate and stable power supply;
• Reliable connections (RF, data, power supply);
• Reasonably arranging the antenna system to achieve a good strength of receiving signal;
• The correct operating parameters of programmed radio modem (frequency、serial port baud rate、
air baud rate、power level、protocol type, etc.);
• Interfaces of radio modem and data equipments connected correctly.
