Extron electronic manual Symbol Definitions, DVS 304 Series • SIS Communication and Control

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 Response References” section.

X! = Specific port number (01-99)

X@ = Command data section

NOTE: 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); for example, 06/21/02-10:54:00

Read format (day, date month year (HH:MM:SS), for example, 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 (for example, 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

NOTE: If tagged responses is enabled, all read commands will return the constant string and

the data, like setting the value does (for example command: Esc CN }, response: Ipn •

X1@])
