TTL / RS232 / RS485 200m Wireless USB Module for Smart Card

 TTL/RS232/RS485 200m RF module for Smart Card Approved by CE JZX863

Modules pin definitions

   JZX863 module J1 Interface Block, a total of five pins, defined in detail as follows:

Features:

1. Power and receiving sensitivity 
The transmission power is <10mW, Receiving sensitivity: -110dbm,
Transmission current<100mA, Receiving current<10mA, sleeping current <1uA.
 

2. Modulation mode and Frequency 
Modulation mode: FSK, Frequency: 433mhz. Also capable of 315mhz, 868mhz and 915mhz.
 

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 datas 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 distance isBER=10-3/1200bps >500m when the antenna is higher than 200m (BER=10-3/9600bps).
