RS232
The main serial interface is used in this case for point-to-point connections; it handles
communication with the Host computer and allows both transmission of code data and
configuring the scanner.
The following pins of the Main Interface connectors (Figure B, 4 or 5) are used for RS232
interface connection:
Connector Name Function
25-Pin 9-Pin
17 2 TXD transmit data
5 3 RXD receive data
19 5 GND Ground
18 7 CTS clear to send
6 8 RTS request to send
It is always advisable to use shielded cables. The overall maximum cable length must be
less than 15 m (49.2 ft).

The RTS and CTS signals control data transmission and synchronize the connected devices.
If the RTS/CTS hardware protocol is enabled, the DX8200 activates the RTS output to
indicate a message can be transmitted. The receiving unit must activate the CTS input to
enable the transmission.
