Chapter 3: Installation

3.4.2 Control by RS-232 serial

Where the external control is via RS-232 signal, ensure that the configuration menu option is set to or to enable RS-232 control.

3.4.2.1 Serial port parameter settings

Ensure that the chosen serial port is configured to the following:

Baud rate:

To match setting of option in the Configuration menu

Data bits:

8

Stop bit:

1

Parity:

None

3.4.2.2 Serial port channel selection codes

 

 

ASCII

 

 

 

 

Character

Hex

Decimal

Channel 1:

‘1’

0x31

49

Channel 2:

‘2’

0x32

50

Channel 3:

‘3’

0x33

51

Channel 4:

‘4’

0x34

52

Note: As each channel is chosen using the above RS-232 commands, the peripherals that will be transferred are determined by the current setting of the switching mode.

3.4.2.3 Control by channel select input lines

Where the external control is via the four channel select input lines of the OPTIONS port (see pin out), ensure that the configura- tion menu option is set to to enable the input lines.

The four input lines are suitable for connection to dry contacts or open collector style outputs. Connecting an input line to GND will cause the Wizard DP USB unit to switch all of its functions to the selected channel:

Channel 1: Channel select input 1 low

Channel 2: Channel select input 2 low

Channel 3: Channel select input 3 low

Channel 4: Channel select input 4 low

If the input line is held low then all other switching requests by other means will be ignored until the line returns to a high (open) state.

If more than one logic input is low (closed) then the lower channel number takes priority.

Note: The input lines have only limited protection against over voltage.
