Channel switching via RS232 control
The Adder SmartView Multiscreen Serial can be controlled by a remote RS232
serial device. To do this, the serial device must be connected to the
OPTIONS/
FLASH
port on the rear panel of the unit using an appropriate link cable.

The serial device must use the following speed/protocol settings:
1200 baud, 8 bits, no parity and 1 stop bit.
No handshaking is used by the SmartView Multiscreen Serial.
To perform the switching operation, simply send the character for the required
channel, for example ASCII ‘1’ (hex code 31) will select channel 1, ASCII ‘2’ (hex
code 32) will select channel 2 and so on. The SmartView Multiscreen Serial will
echo the ASCII character back to the sending device when the channel has been
changed.
Pin assignments for the
OPTIONS/
FLASH
port on the rear panel are
as follows:
Pin 9 = GND
Pin 10 = TXD
Pin 11 = RXD
Other pins to be left unconnected.
