- Page 2 8. Wireless intellectual over-weight detecting system 9. Queue management system in the bank, hospital, hall etc Introduce: Wireless transceiver module HR-1025 can be used in any standard or nonstandard user protocol The module has highly be avoided disturbance ability, long transmission range, the distance can extend to 4500m (1200bps) in open field.
- Page 3 ORIENTAL HUARAY GROUP LIMITED Ⅲ、Interface definition: HR-1025 (V1.1) module can supply a 9-pin connecter (CON1), and its definitions as well as connection method for terminals are following show: Tel: 86 755 81782516 Cell: 86 15813856667 Fax: 86 755 81782518 Website:...
- Page 4 There is one group of 5-bit short-circuit wire(J1) on the bottom left corner of HR-1025, defined as A, B, C, D, E respectively, assuming the open circuit wire (with short circuit) is mode 0...
- Page 5 ORIENTAL HUARAY GROUP LIMITED Above figure is do not input the jumper, input jumper means make the two points join together as the following show: 4.2 Channel configuration: ABC jumper wires of J1 provide 8 options and you can choose 0-7 channels (ABC jumper wire mode is the same), you can transmit data between each module, but keep in mind at the same time only one modules is in TX mode.
- Page 6 ORIENTAL HUARAY GROUP LIMITED 4.3. Selection of interface mode: HR-1025 (V1.1) provides there types of interface mode, COM1 (Pin3 and Pin4 of CON1) is fixed as UART Serial port of TTL level: COM2 (Pin6 and Pin7 of CON1) can choose interface mode (RS-232, RS485) through D of J1 (1).
- Page 7 ORIENTAL HUARAY GROUP LIMITED Note: Please do not connect any wire on Pin6 and Pin7 and also if the other wire you do not use, please cut them down, or it will has interface. If you use the TTL only please make sure the D jumper of JP2 without jumper wire (D=0) (2).
- Page 8 ORIENTAL HUARAY GROUP LIMITED Note: If the module and the equipment use different power supply, please make sure the two use the same GND (join the two`s GND together). (3). RS-485 interface connection application circuit Note: Do not connect other wires or it will has interface...
- Page 9 3. When the module receive the data from air, the Green led will flash again Ⅵ、Time diagram: HR-1025 has sleeping mode, it is controlled by SLP pin, usually the SLP is in the high level mode (SLP=1), if you need the modules in the working mode, you need...
- Page 10 ORIENTAL HUARAY GROUP LIMITED Transmit timing delay When the RXD of the HR-1025 (named A) receive data, then the modules send the data to modules B(HR-1023), then the TXD output the data, between those transmit it has a timing delay (Td), different baud rate has different delay time, example: when you choose 1200bps, you need add 122ms delay in your program.
- Page 11 ORIENTAL HUARAY GROUP LIMITED Ⅷ、Technology support and sold service: We offer sufficient technology support for user use the module and further development for free, mending broken module one year for free, always offer after service, to adapt different user structure, we can develop smaller module or various size modules.
