Galil DMC-1800, DMC-1700 user manual Example - Using the LZ command, PF m.n

PF m.n

where m is the number of digits to the left of the decimal point (0 thru 10) and n is the number of digits to the right of the decimal point (0 thru 4) A negative sign for m specifies hexadecimal format.

Hex values are returned preceded by a $ and in 2’s complement. Hex values should be input as signed 2’s complement, where negative numbers have a negative sign. The default format is PF 10.0.

If the number of decimal places specified by PF is less than the actual value, a nine appears in all the decimal places. Examples:

:DP21	Define position
:TPX	Tell position
0000000021	Default format
:PF4	Change format to 4 places
:TPX	Tell position
0021	New format
:PF-4	Change to hexadecimal format
:TPX	Tell Position
$0015	Hexadecimal value
:PF2	Format 2 places
:TPX	Tell Position
99	Returns 99 if position greater than 99

Removing Leading Zeros from Response to Interrogation Commands

The leading zeros on data returned as a response to interrogation commands can be removed by the use of the command, LZ.

Example - Using the LZ command

LZ0	Disables the LZ function
TP	Tell Position Interrogation Command
-0000000009, 0000000005, 0000000000, 0000000007	Response from Interrogation Command
	(With Leading Zeros)
LZ1	Enables the LZ function
TP	Tell Position Interrogation Command
-9, 5, 0, 7	Response from Interrogation Command
	(Without Leading Zeros)

Local Formatting of Response of Interrogation Commands

The response of interrogation commands may be formatted locally. To format locally, use the command, {Fn.m} or {$n.m} on the same line as the interrogation command. The symbol F specifies that the response should be returned in decimal format and $ specifies hexadecimal. n is the number of digits to the left of the decimal, and m is the number of digits to the right of the decimal. For example:

Examples:

TP {F2.2}	Tell Position in decimal format 2.2
-05.00, 05.00, 00.00, 07.00	Response from Interrogation Command
TP {$4.2}	Tell Position in hexadecimal format 4.2
FFFB.00,$0005.00,$0000.00,$0007.00	Response from Interrogation Command
