Connecting Fingerprint

Controller and Computer

Connection to Computer via RS232

As other EverAccess Flex series controller, the fingerprint controller is able to operate as a

stand-alone device or as a networked device, connected directly to a PC via serial port.

Fig. 16. Connecting Fingerprint Controller to a PC

To connect the fingerprint controller to the computer via RS232, the communication terminals

should be wired to the computer serial port as follows: the RS232 TX terminal of the controller

is linked to the RS232 RX of the serial port and the RS232 RX terminal is linked to the TX.

Note that 15 meter is the max distance of RS232 connection from fingerprint controller to

computer. Please use RS485 bus if the distance is longer than 15m.

Fig. 17 describes how to connect the DB9 port to the computer serial port. If a self-made

cable and interface is used for connection, then a DB9 female connector is required. The

terminal 27, 28 and 29 should be linked to the pin 2, 3 and 5 respectively, which are RXD,

TXD and GND.
