Serial Data Example

Here is an example of a message containing variables, which is triggered

using the serial link. The example message (number 4) is:

Voltage = ↑, current = ↑

To trigger this message, the following strings are sent:

ASCII (Ctrl V) 4 1 6 0 [Return]

Decimal Equivalent: 22 52 49 54 48 13

Hex Equivalent: 16 34 31 36 30 0D

Octal Equivalent: 26 64 61 66 60 15

This queues up 4160 as the “voltage” value.

ASCII (Ctrl V) 1 2 0 0 [Return]

Decimal Equivalent: 22 49 50 48 48 13

Hex Equivalent: 16 31 32 30 30 0D

Octal Equivalent: 26 61 62 60 60 15

This queues up 1200 as the “current” value.

ASCII (Ctrl T) 4 [Return]

Decimal Equivalent: 20 52 13

Hex Equivalent: 14 34 0D

Octal Equivalent: 24 64 15

This queues up a trigger for message number 4, which causes this message to

be displayed:

Voltage = 4160, Current = 1200

Note: Don’t forget that the DL20 must be set up for BINARY MSG & VAR

DATA of the parallel port options for serial port queuing to work. This is

selected from the special functions menu.
