Embedding a Decimal Point

You can display numbers which have decimal points. The decimal point is
inserted just like any other character and it takes up one full character space.
Insert a decimal point before or after the [CTRL] [V] by typing [

]. For

example, the following steps would be required to create the message
“SPEED IS . FPS”.

1. Enter the following message:

2. Enter the first variable digit by pressing the [Ctrl] and [V] keys:

3. Press the [.] key to enter the decimal point. Notice that the decimal point

requires a character position. The decimal point becomes a part of the
variable.

4. Then enter the second variable digit by pressing [Ctrl] and [V] keys.

5. Finish entering the message by typing [F] [P] [S].

Note: Use [CTRL][X] to imbed variable digits with leading zeros.
[CTRL][V] imbeds variable digits without leading zeros.

Sending Variable Data Through
the Serial Port

Use the CTRL-V command to send data for display in Binary, BCD,
Numeric, Priority, and Round Robin modes. All values are decimal values.
The command has the following format:

where:

– Variable Data is 1 to 5 ASCII digits (0-65535)

– Variable Position is single ASCII digit (value is ignored)

– DL5 Address is 1 to 3 ASCII digits (0-127)

For example, to send a value of 500 to a DL5 with an address of 99, the
following string would be sent:

Note: In Binary mode, variable data can be in the range 0 to 16,383. In
BCD mode, variable data must be in the range 0 to 3999. In Round Robin.
Priority and Numeric modes, variable data can be in the range of 0 to
65535.

Note: The CTRL-V command in Priority, Round Robin and Numeric
modes triggers messages not variables.
