hm - trp - rs485 series 100mw transceiver modules v1.0 6 . led function the hm - trp - rs485 add the led function for easier debug & function demo, thus the users can easily u nderstand whether the module is working or not or in any other status. led function: 1. the red and green led will flash when there is power on if the module start working. 2. the module will be ready for config status if enable pin is low config pin is low. it will be in config if the red and green led keep lighting. the green and red led will not keep lighting if the module is not in config mode. 3. the red led flash when the module is in transmission the red led will be off if the trans mission finished. 4. the green led is off when the module is in receiving status, the green led will flash once if the module receive data. 7 . config instruction you need to config the parameter and inquiry for different need to realize the function. the hm - trp - rs485 can config and inquiry for working frequency, wireless data rate , receiving ism bandwidth, frequency deviation, transmission power, rs - 485 transfer baud rate & rssi signal reading etc. config and inquiry methods: the module will be ready f or config status if enable pin is low config pin is low. it will be in config if the red and green led keep lighting. then you can config & inquiry on the module. the config instruction format is as aa fa+[instruction]+[parameter].the instruction is 1 byte the parameter is the hex data of 0 - 4 byte which the high byte before the low byte. the instruction?s transfer speed should keeps the same as the transfer speed of rs - 485 . the instruction?s transfer speed will change accordingly if changes the transfer s peed of rs - 485 .the range of transfer speed of the instruction is from 1.2kbps ? 115.2k bps. config& inquiry instruction description: 1. instruction[f0]: reset to default parameter, no parameter follows config instruction aa fa f0 2. instruction[e1]: re ading the current config parameter, no parameter follows config instruction aa fa e1 3. instruction [d2]: set up working frequency [parameter]4 byte [parameter] unit :hz set up range: hm - trp - rs485 - 433: 414000000 - 454000000hz hm - trp - rs485 - 470: 450000000 - 49 0000000hz hm - trp - rs485 - 868: 849000000 - 889000000hz 3 tel: +86 - 755 - 82973805 fax: +86 - 755 - 82973550 e - mail: sales@hoperf.com http://www.hoperf.com unregistered
