The allowed supply voltage range is 10 to 30 Vdc.
5.5 MAIN SERIAL INTERFACE
The signals relative to the following serial interface types are available on the 25-pin
connector.
The main serial interface type and its parameters (baud rate, data bits, etc.) can be
defined by the user via VisiSet™ software. The RS485 half duplex is automatically set
whenever MUX32 communication protocol is enabled. For more details refer to the
"Communication" folder in the VisiSet™ Help On Line.
Details regarding the connections and use of the interfaces are given in the next paragraphs.
5.5.1 RS232 Interface
The opto-isolated 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:
Pin Name Function
2 TX Transmit Data
3 RX Receive Data
4 RTS Request To Send
5 CTS Clear To Send
7 GND_ISO Main opto-isolated reference ground
It is always advisable to use shielded cables. The overall maximum cable length must be
less than 15 m (49.2 ft).
