10 Power Failure Protection
The card will be back to users when backup capacitor connected during main power down.
10.1 Power Failure Definition
1) Power failure value:<20V
2) Power failure lasting time:>15ms
10.2 Power Failure Troubleshooting Process:
When power failure occurred during card reader’s operation,the card inside will be driven to the front by
resetting initialization command Pd Wv and the stored power of backup capacitor.
Remarks: During power failure, the card reader won’t respond RS232 communication and DSR_PIN
displays OFF status.
More specifications on Pd,Wv,pls refers to the communication protocol of CRT-350-NJ10.
10.3 Power Failure Recovery:
The card reader will start communication and DSR_PIN will move to ON status once the main power
reaches 20V above.
10.4 Backup Capacitor Specs.:
1) Capacitor level: >0.33F(Withstand voltage >50V)
2) Capacitor output
：
18~25V Constant 2A output
