3-5 DVS 304 • Serial Communication
Symbol definitions
• = Space
] = Carriage return with line feed
} = Carriage return with no line feed
E
= Escape
14, 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.
X!
= Specific port number (01-99)
X@
= Command data section
N 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).
X#
= Greenwich Mean Time (GMT) offset value
(-12:00 to 14:00) in hours and minutes
(hh:mm)
X%
= On/Off
0 = off/disable
1 = on/enable
X1!
= Version number
(listed to 2 decimal places)
X1@
= 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.
X1#
= 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
X1$
= IP address (xxx.xxx.xxx.xxx); leading zeros
in each of 4 fields are optional in
setting values, and are suppressed in
returned values.
X1%
= Mail domain name (e.g., Extron.com)
X1&
= 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, X1& is
optional.
X1*
= Hardware (MAC) address
(xx-xx-xx-xx-xxxx)
X1(
= Subnet mask (xxx.xxx.xxx.xxx). Leading
zeros are optional in setting values in each
of four fields, and are suppressed in
returned values.
X2!
= Parameter to set either the Length of the
message to receive or a Delimiter value.
L = byte count (min = 0, max = 32767, and
default = 0L [0 byte count).
D = decimal value for the ASCII
character (min = 0, max = 00255, and
default = 00000D).
Value is placed prior to parameter; for
example, 3 byte length = 3L, and the
ASCII 0A delimiter is 10D. This
parameter is case sensitive; you must use
uppercase D and L. The response is
returned with leading zeros. (
X2!
is an
optional parameter.)
X2@
= 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
N If tagged responses is enabled, all read
commands will return the constant string +
the data, like setting the value does
(e.g. command: Esc CN } response:
Ipn • x12 ] ).
X3# = Password (12 characters = maximum
length; no special characters are allowed.)
N 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.
X3$ = Daylight savings time (used in the
northern hemisphere [USA] and parts of
Europe and Brazil)
0 = off/ignore
1 = on
2 = Europe
3 = Brazil
X3%
= Event number, range: 0 - 99
X3^
= Event buffer:
0 = receive
1 = unified
2 = data
3 = NVRAM
