Symbol definitions

] = CR/LF (carriage return/line feed) (hex 0D 0A)

}= Carriage return (no line feed) (hex 0D)

For Web browser commands, use the pipe character () instead of the soft return.

= Space character

= Pipe (vertical bar) character

E = Escape key (hex 1B)

 

For Web browser commands, use W

 

instead of E.)

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)

 

The port number is represented as two

 

ASCII characters (2 bytes). For example,

 

port 05 would be represented as 30 35 in

 

hexadecimal.

 

01 = RS-232/422 port (rear panel)

 

02 = Config port (front panel)

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 two decimal

 

 

places)

X1@ = Unit 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, day month

 

 

year) (HH:MM:SS), e.g., Fri, 26 Sep 2008

 

 

18:19:33

X1$ = IP address (xxx.xxx.xxx.xxx); leading zeros in each of four 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 the

response via the serial port Default = 10 (100 ms) Maximum = 32767

X1* = Hardware (MAC) address (xx-xx-xx-xx-xx-xx)

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) = Time in tens of milliseconds to wait between characters received via the serial port Default = 20 (200 ms)

Maximum = 32767

X2! = Message length, delimiter value, or byte count (via the serial port)

#L = Length of message to be received #D = Delimiter value

# = byte count (1 through 32767; default = 0)

X2@ = Verbose response mode 0 = clear/none

1 = verbose mode

2 = tagged responses for queries

3 = verbose mode and tagged responses for queries

Default = 0 for Telnet connections; 1 for RS-232/422 control.

NIf tagged responses are enabled, all read commands return the constant string plus the data.

Example:

Command: E CN }

Response: Ipn X1@ ]

X2% = Baud rate: 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600, 14400, 19200, 28800, 38400, 57600, or 115200

X2^ = Parity (only the first letter is needed): Odd

Even

None

Mark

Space

X2& = Data bits: 7 or 8

X2* = Stop bits: 1 or 2

X2( = Port type

0 = RS-232

1 = RS-422

X3) = Flow control

H = hardware S = software N = none

X3! = Data pacing (0000-0001 ms between bytes) Default = 0 ms

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.
