5.4.1 RS232 Interface
The RS232 interface can be used for Point-to-Point, Pass Through or Master/Slave
connections. When it is connected to the host computer it allows both transmission of code
data and reader configuration by VisiSet™.
The following pins of the 25-pin connector are used for RS232 interface connection:

Figure 64 - RS232 Main Interface Connections Using Hardware Handshaking
The RTS and CTS signals control data transmission and synchronize the connected devices.
Figure 65 - RS232 Control Signals
If the RTS/CTS handshaking protocol is enabled, Matrix
210™ activates the RTS output to
indicate a message is to be transmitted. The receiving unit activates the CTS input to enable
the transmission.
