HM-TR v2.2 HM-TR Series UHF Wireless Transparent Data Transceiver General The HM-TR series UHF wireless transparent data transceiver, developed by Hope Microelectronics Co. Ltd, is designed for applications that need wireless data transmission. It features high data rate, longer transmission distance, programmable frequencies, configurable UART formats and low sleep current make it ideal choice. The communication protocol is self controlled and completely transparent to users. The module can be embedded to your existing design so that low cost high performance wireless data communication can be utilized easily. Features 1. FSK (Frequency Shift Keying) modulation, high interference immunity 2. 2-way half-duplex communication 3. 315/433/868/915MHz ISM band, globally license free. 4. Programmable frequencies, allowing be used in FDMA (Frequency Division Multiple Access) applications 5. Self controlled RF to UART protocol translation, reliable and easy to use. 6. Configurable UART format, with data rate from 300~19200bps 7. Using ENABLE pin to control duty-cycle to satisfy different application requirements 8. High performance, long transmission range. >300m in open area 9. Standard UART interface, with TTL or RS232 logic level available 10. Compact size, standard 0.1” pinch SIP connector and SMA antenna socket 11. No RF tuning needed in application Application Areas 1．Remote control, remote measurement system 2. Wireless metering 3. Access control 4. Identity discrimination 5. Data collection 6. IT home appliance 7. Smart house products 8. Data store and forward repeater Overview and Pin assignment HM-TR/232 HM-TR/TTL Note: The ‘232’ version has a on-board MAX232CSE converter, which is not fitted on the ‘TTL’ version Tel: +86-755-82973806 Fax: +86-755-82973550 E-mail: [email protected] http://www.hoperf.com update: 6/16/2008 HM-TR v2.2 Pin 1 2 3 4 5 name VDD DTX GND DRX CONFIG 6 ENABLE note Power supply Data output from module Ground Data input to module If this pin is high at power on, module will enter configure mode, while it communicates if set low If this pin is low in normal mode, the module will enter sleep mode immediately.
