$AA1L
Name: Read Non-isolated Low Trigger Level.
Description: Read the low trigger level for non-isolated input signals of a
specified counter/frequency module.
Syntax: $AA1L(cr)
$ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of counter/frequency module that you want to interro-
gate.
1L identifies the Read Non-isolated Low Trigger Level
(cr) is the terminating character, carriage return (0Dh)
Response: !AA(data)(cr) if the command is valid.

(data) is the low trigger level of non-isolated input signal. The
unit and resolution are both 0.1 V (voltage). The format is a
two digit integer that can range from 1 to 50 ( i.e. 0.1 V
to 5 V ).
(cr) is the terminating character, carriage return (0Dh).
Example: command: $051L(cr)
response: !0508(cr)
The command requests the counter/frequency module at
address 05 to read its non-isolated input signal low trigger
level. The addressed module replies that its low trigger level is
0.8 V.
