$AA1H
Name Read Non-isolated High Trigger Level command
Description Read the high trigger level for non-isolated input signals of
a specified counter/frequency module.
Syntax $AA1H(cr)
$ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address that you will access to.
1H is the Read Non-isolated High Trigger Level command.
(cr) is the terminating character, carriage return (0Dh).
Response !AA(data)(cr) if the command is valid.

(data) is the high trigger level of non-isolated input signals
The unit and resolution are both 0.1 V (voltage). The
format is a two digit in teger t hat range from 1 to 5 0 (i.e. 0. 1
V to 5 V).
(cr) is the terminating character, carriage return (0Dh).
Example command: $131H(cr)
response: !1330(cr)
The command requests the counter/frequency module at
address 13 to read its non-isolated high trigger level. The
module replies that the high trigger level is 3 V.
