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.
