• = Space

= Carriage return with line feed

}= Carriage return with no line feed

E= Escape

= Superscripts indicate the error message displayed if the command is entered incorrectly or with invalid parameters. See “Error responses”, earlier in this chapter.

= Specific port number (01-99) = Command data section

NFor 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

NIf 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.)

NA 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
