
Reads the timeout value
$AAJN [timeout] [chk] (CrLf)

Sets the timeout value
Note: Supported by the firmware version 3.0 and upward.

Syntax:
$AAJN[timeout] [chk] (CrLf)
$ Delimiter character
AA 2-character module address in HEX format. The valid range is from
00 to FF
N=0 COM 2 timeout0
N=1 COM 1/3/4/5/6/7/8 timeout1
N=2 COM 1/3/4/5/6/7/8 timeout2
[timeout] Delay time value (ms). Valid range is 0 to 4294967259.
[chk] 2-character checksum. If the checksum is disabled

no [chk]
(CrLf) End Character

Response : valid command

!AA[timeout value][chk](CrLf)
invalid command

?AA[chk](CrLf)
no response

buffer is empty, syntax error, communication error, address error
! Delimiter character indicating a valid command

(CrLf) End Character

Example: (Assume the AA address value of the I-7522 module is 01)
command: $01J01000(CrLf)
response: !01(CrLf)
command: $01J11500(CrLf)
response: !01(CrLf)
command: $01J1(CrLf)
response: !011500(CrLf)
The default timeout1 value for all RS-232 COM ports is 1000ms.

Notes:
RS-485: timeout0
Sets the timeout value for the RS-485(COM 2 ) to 1000ms
Sets the timeout value of the RS-232(COM 1) to 1500ms
Reads the timeout1 value of COM1
The timeout1 value of COM1 is 1500ms.
