- Use the screws to fix the plate on the wall, and then fix the device on the plate.
- After installation, please make sure the device is reliable, fasten, and stable.
Communication Connection
There are two ways that the PC software communicate and exchange information with the device: RS232 and TCP/IP.
Ethernet Mode
- Connects with PC through cross cable, as the figure 3-1.
- The device and the PC both connected to LAN/WAN through Switch/LAN switch as figure 3-2.
RS232 Mode
We will provide a RS232 cable with the device. Connect the device with the PC
serial port through this cable, as figure 3-3. Only four terminals are used
for RS232 communication: SGND, RXD, TXD, and GND. Plug the DB 9 PIN side of
the cable into the PC port, the other side plug into the device terminals, as
figure below. PC 9 PIN

External Ring and the Lock Connection
Note: The external ring and unlock function are both optional functions and they can not use together. If you need to use any one of them, please contact our business representative or technical support.
-
Electric lock connection：
After the user verified the identity, the device will output the unlock signal.
The device supports NO LOCK and NC LOCK. For example the NO LOCK (normally open at power on) is connected with “NO” terminal, and the NC LOCK is connected with “NC” terminal.
Normally Closed Lock:
The lock is normally closed at power on, the connection as figure 3-4.
Normally Open Lock:
The lock is normally open at power on, the connection as figure 3-5. -
External Ring：
Connect the electrical bell to the device, when arrive the appointed time, the device will send a signal to trigger the relay. The connection please refers to the figure 3-6.
Printer Connection
This function is designed for a serial port printer only, the parallel printer
is unavailable. After a user is verified, the result will be sending out
through serial port. If the device is connected with the printer, the result
can be printed directly. We will provide a 25 PIN to 9 PIN female extension
cable, and a 9 PIN to terminal cable, the connection as figure below. 
Only four terminals are used for RS232 communication: SGND, RXD,
TXD, and GND. Plug the DB 25 PIN side into the printer port, the other side
connect with the other cable 9 PIN side, the left terminal side plug into the
device terminals, the connection and the terminal definition as figure below.
