- 1 - HAC-LN96 Low Power Radio Data Module I. Features of HAC-LN96 Low Power Radio Data Module 1. Low power transmission with the transmission power of 800mW 2. ISM frequency band, requiring no application of frequency point. Carrier frequency of 902~910MHz. 3. High anti-interference and low BER(Bit error Rate) Based on the FSK modulation mode, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both burst interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2. 4. Long transmission distance Within the range of visibility, the reliable transmission distance is >1500m when the height is greater than 2m (BER=10-3/9600bps). Within the range of visibility, the reliable transmission distance is >2500m when the height is greater than 2m (BER=10-3/1200bps). 5. Transparent data transmission Transparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). 6. Channel allocation and frequency: This module has 64 channels which are tagged through 0 to 63, channel alternation is 115.2KHz, initial channel 0 has the frequency of 902.3324MHz and the ending channel is working at 909.5900MHz. 7.Dual serial port, 3 interface modes HAC-LN96 provides 2 serial ports and 3 interfaces, with COM1 as the TTL level UART interface and COM2 as user defined standard RS-232/RS-485 interface (user only needs to plug/pull 1 bit short circuiter and energize it to make the definition). 8.Large data buffer zone Interface baud rate is 9600bps with format of 8N1/8E1 and user self-definition, allowing the transmission of long data frames at one time for more flexible programming by users. (If the user needs, it can also transmit the data in unlimited length at one time). 9.Intelligent data control and the user doesn’t need to prepare excessive programs Even for semi duplex communication, the user doesn’t need to prepare excessive programs, only receiving/transmitting the data from the interface. HAC-LN96 will automatically complete the other operations, such as transmission/receiving conversion in the air, control, etc. 10.Low power consumption and sleeping function Power Supply: 7.2VDC, Maximum Current: 500mA. Maximum Transmission Power: 800mW. Receiving Current: 50mA. 11.High reliability, small and light Single chip radio-frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate.

Application of HAC-LN96 Series low power Radio data module HAC-LN96 series low power radio data module is suitable for: Wireless meter reading Industrial remote control and remote test Automatic data collecting system Building automation, safety and security, powerhouse equipment wireless monitor, entrance control system POS system, wireless keyboard, mouse III. How to use HAC-LN96 series low power radio data module HAC-LN96 series low power radio data module provides three interface modes including standard RS-232, RS-485 and UART/TTL levels allowing direct connection with computer, user’s RS-485 device, monolithic processor and other UART components for application. The schematic circuit of HAC-LN96 is shown below: 1. Power supply HAC-LN96 uses DC power supply with voltage of 7.2V. Under working condition, transmission current is ≤500mA, receiving current is ≤50mA . 2. Definition of HAC-LN96 connecting terminal HAC-LN96 can supply one 9-pin connector (JP1), and its definitions as well as connection method for terminals are shown in Table 1.

Setting of channel, interface and data format: Before using HAC-LN96, the user needs to make simple configuration based on its own needs to determine the channel, interface mode and data format. There is one group of 5-bit short-circuit jumper wire (JP2) on the upper right corner of HAC-LN96, defined as ABCDE respectively. Assuming the open circuit of jumper wire (without short circuiter) is mode 1 and short circuit of jumper wire (with short circuiter) is mode 0, then the configuration is as follows: a. Channel configuration: Channel configuration is done through single byte command plus swap enabling signal. Detail is as following: Pin8 of JP1 is defined as CH_EN for swap enabling, it is used as an input signal to the wireless module and it usually is connected to one of the output ports on customer’s MCU. When this pin is set to 1, the wireless module will be transmitting data normally. On the other hand, when this pin is set to 0, then the module is waiting to be configured by the 1 byte channel command – which is the channel ID. As a confirmation, the wireless module will return the configured 1 byte channel ID within 2ms after it received the channel command. By resetting CH_EN to 1 the wireless module will exit from the configuration mode. The configuration timing sequence is as following: In Which：CH_EN is an input signal to the wireless module。 RxD is an input signal to the wireless module。 TxDis an output signal to the wireless module。
- 4 - b. Selection of interface mode: HAC-LN96 provides 2 serial ports. COM1 (Pin3 and Pin4 of JP1) is fixed as UART serial port of TTL level; COM2 (Pin6 and Pin7 of JP1) can choose interface mode through D of JP2: D=1 (without short circuiter) COM2 = RS-485 D=2 (with short circuiter) COM2 = RS-232 The following attention should be paid for the two serial ports provided by HAC-LN96: i. For the data received from the air, when HAC-LN96 transmits it to the terminal equipment through serial port, COM1 and COM2 output simultaneously, i.e. if the user connects one device at COM1 and COM2 respectively, they can receive the data simultaneously. ii. For the data transmitted from the terminal equipment and ready to transmit to the air, HAC-LN96 can only receive the data sent from either COM1 or COM2 but not simultaneously. Suggestion: The user only connects to use one serial port of COM1 or COM2. c. Parity mode selection: HAC-LN96 can support no-parity or even parity modes of the serial communication UART, i.e. 8N1/8E1. It can choose parity mode through E of JP2: E=1 (without short circuiter) Parity: 8E1 (even parity) E=0 (with short circuiter) Parity: 8N1 (no parity) Note: The user can’t set the communication rate of HAC-LN96 itself. The user chooses when placing the order and it is already set when delivered from the factory. 5. Sketch map of structural size (see below): IV. Application of series HAC-LN96 networking The communication channel of HAC-LN96 is semi duplex, which is most suitable for the communication mode of point to multi-point. Under this mode, one master station must be set, and all of the rest are slave stations. A unique address is given to each station. The coordination of communication is controlled by master station that uses data frames containing address code to transmit data or command. Slave station will receive all of the data and command and compare the received address code with local address code. If they are different, the data will be deserted without any response. If those address codes are the same, it means the data is sent to the local. Slave station will make different responses according to the transmitted data or command and send back the data of response. All these jobs must be performed by upper protocol, and it is assured that there is only one transmitter-receiver in the state of transmission in the communication network at any instant moment so as to avoid the cross-interference. HAC-LN96 can also be used for point-to-point communication with easier operation. For the programming of serial port, all you have to do is to remember that its communication mode is
- 5 - semi duplex while always observing the time sequence of come-and-go for receiving and transmitting. V.
