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
