Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 11. INTEGRATION GUIDE LinkWiser™-S400M Rev. 2.1 owns a voltage regulator which always supplies 2.8VDC to the entire circuit except POWER APLIFIER that receives 6.5VDC ~ 24VDC of input voltage directly. And this is for stable operation & performance especially in RF front end side. Nevertheless, qualified external power supply is necessary, which must be in 6.

CONFIGURATION This section describes the configuration and test commands supported by the radio module. In most cases, once the configuration is set it will not need to be changed. Configuration is performed using a serial terminal, or appropriate communication application.
Technical Datasheet & User’s Manual ATO AT/V Register Handling Command Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 Communication mode activation ‘ATO’ command gives an instant access to the module’s Operating mode. ‘ATO’ command is used to get out of Configuration Mode. Answer: Good Bye! ‘AT/V’ command displays the module’s firmware version Ex) AT/V ‘S424V1.0’ // LinkWiser-S, 424MHz, V1.0 ‘HP915V2.0 // LinkWiser-HP, 915MHz, V2.
Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 ‘1’: Enabled R/W ATS132 Repeater Address Ex): Assuming that S130 = ‘0’ & S131 = ‘1’, the TX data will automatically routed to & by the repeater(address defined by S132) Repeater Address Ex): Assuming that S130=’1’, this register will set the desired repeater’s address. All data will be sent to the repeater node first, and that repeater will automatically route the data to the preset destination.
Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 The addressed mode is similar to a multipoint mode. All modules can communicate with each other by addressing each frame to one of them. 12-3-1 Operation Addressed mode’s purpose is to offer an optimal radio link performance providing the multipoint access of the transparent mode.

Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 Figure1 Typical System Block Diagram Data is sent and received in standard ‘RS232’ serial format and there is no restriction on characters that may be sent. If you configure “Serial Link Time Out” value more than one byte interval, the data flow look like Figure2, but if you configure “Serial Link Time Out” value less than one byte interval, the data flow looks like Figure3.
Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 12-5-3 UART Timing in Tx You MUST configure the Serial Link Time Out value depending on DEPENDING ON YOUR SERIAL BAUD RRATE. EX) If your serial baud rate is 9600bps, we recommend over 1ms of the Serial Link Time Out value. Thus, you can get a result same as the above Figure2. 9600bits/second = 9600bps, then 960bytes/second because start bit & stop bit should be added.
Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 9600bps of baud rate & 4800bps of air rate in order to transmit 50 bytes of data. 12-6 TERMINAL SETTING A typical terminal setting 1. Please connect the LinkWiser-S400M to RS-232C in your PC. 2. Please make sure that the mode switch is set to RS-232C before power on. And also please make sure that the input voltage range is within 6VDC to 24VDC. 3.
Technical Datasheet & User’s Manual Narrowband multi-channel data radio modem LinkWiser™-S400M Rev. 2.1 You can use the “Set Macros” function to make easier to write & read our AT command sets. However, “$0D$0A” string should be followed for carriage return in this case.
