Symbol definitions
• = Space
= Carriage return with line feed
= Carriage return with no line feed
Esc
= Escape
24, 27, 28
= Superscripts indicate the error message
displayed if the command is entered
incorrectly or with invalid parameters. See
Error responses,
earlier in this chapter.
X1
= Specific port number (01-99)
X2
= Command data section
For Web encoding only:
Data is directed to the specified port and
must be encoded if it is non-
alphanumeric. Because data can
include either command terminator, it
must be encoded as follows when used
within the data section:
Space
(Hex 20) must be encoded as
%20 (Hex:25 32 30)
Plus sign
(Hex 2B) must be encoded as
%2B (hex 25 32 42).
X3
= Greenwich Mean Time (GMT) offset value
(-12:00 to 14:00) in hours and minutes
(hh:mm)
X5
= On/Off
0 = off/disable
1 = on/enable
X11
= Version number
(listed to 2 decimal places)
X12
= Name is a text string of up to 24 characters
drawn from the alphabet (A-Z), digits (0-9),
and the minus sign/hyphen (-). The first
character must be an alpha character. The
last character must not be a minus. No
blank or space characters are permitted,
and no distinction is made between upper-
and lowercase.
X13
= Local date and time format
Set
format (MM/DD/YY-HH:MM:SS);
e.g., 06/21/02-10:54:00
Read
format (day of week, date month
year (HH:MM:SS), e.g., Thu, 20 Feb 2003
18:19:33
X14
= IP address (xxx.xxx.xxx.xxx); leading zeros
in each of 4 fields are optional in
setting values, and are suppressed in
returned values.
X15
= Mail domain name (e.g., Extron.com)
X17
= Time in tens of milliseconds to wait for
characters coming into a serial port before
terminating the connection (min = 0,
max = 32767, and default = 10 = 100 ms).
The response is returned with leading
zeros. In RS-232 commands,
X17
is
optional.
X18
= Hardware (MAC) address
(xx-xx-xx-xx-xxxx)
X19
= Subnet mask (xxx.xxx.xxx.xxx). Leading
zeros are optional in setting values in each
of four fields, and are suppressed in
returned values.
X21
= Parameter to set either the
L
ength of the
message to receive or a
D
elimiter value.
L
= byte count (min = 0, max = 32767, and
default = 0
L
[0 byte count).
D
= decimal value for the ASCII
character (min = 0, max = 00255, and
default = 00000L).
Value is placed prior to parameter; for
example, 3 byte length = 3
L
, and the
ASCII 0A delimiter is 10
D
. This
parameter is case sensitive; you must use
uppercase D and L. The response is
returned with leading zeros. (
X21
is an
optional parameter.)
X22
= Verbose/Response Mode
(Default = 0 for Telnet connections;
1 for RS-232 host control).
0 = clear/none
1 = verbose mode
2 = tagged responses for queries
3 = verbose mode and tagged responses
for queries
If tagged responses is enabled, all read
commands will return the constant
the data, like setting the value
does (e.g. command: Esc CN ?
response: Ipn ? x12?).
X33
= Password (12 characters = maximum
length; no special characters are allowed.)
A user password cannot be assigned if
no administrator password exists; the
E14 error code is returned. If the
administrator password is cleared, the
user password is also removed.
X34
= Daylight savings time (used in the
northern hemisphere [USA] and parts of
Europe and Brazil)
0 = off/ignore
1 = on
2 = Europe
3 = Brazil
X35
= Event number, range: 0 - 99
X36
= Event buffer:
0 = receive
1 = unified
2 = data
3 = NVRAM
X37
= Event buffer offset
(range: 0 to MaxBufferSize)
