IPL 250 • SIS Programming and Control

sign/hyphen (-). No blank or space

characters are permitted as part of a name.

No distinction is made between upper and

lower case. The first character must be

a letter. The last character must not be a

minus sign/hyphen.

X1#

= Local date and time format

Set

format (MM/DD/YY-HH:MM:SS).

Example: 01/18/05-10:54:00.

Read

format (day of week, date month year

HH:MM:SS). Example: Tue, 3 Jul 2007

18:19:33

.

X1$

= IP address (xxx.xxx.xxx.xxx). Leading zeros

in each of four fields are optional in

setting values, and they are suppressed in

returned values.

IPL 250’s default address: 192.168.254.254

Default broadcast address:

255.255.255.255.

X1%

= E-mail domain name; for example, extron.com

X1&

= Time in tens of milliseconds to wait until the

first

response character is received via a

serial port before terminating the current

receive operation. (Default = 10 = 100

ms, max. = 32767.) The response includes

leading zeros.

N

For commands that use both

X1&

and

X2)

, both

variables must be zero

or both must be non-zero.

In the RS (send data) command,

X1&

may be

omitted as long as

X2)

is also missing.

X1*

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

xx) (00-05-A6-xx-xx-xx) For the location
of this address,

see

h

MAC address in

chapter 2

.

X1(

= Subnet mask (xxx.xxx.xxx.xxx). Leading

zeros are optional in setting values in each

of four fields, and they are suppressed in

returned values. Default = 255.255.0.0.

X2)

= Time in tens of milliseconds to wait between

characters

being received via a serial port

before terminating the current command

or receive operation. The response

includes leading zeros.

(Default = 2 = 20 ms, max. = 32767)

N

For commands that use both

X1&

and

X2)

, both

variables must be zero

or both must be non-zero.

In the RS (send data) command,

X1&

may be

omitted as long as

X2)

is also missing.

X2!

= Parameter (#L or #D) to set either the Length

of message to receive or the Delimiter

value. # = byte count (for L) or

# = a single ASCII character expressed in

decimal form (for D).

The parameter is case sensitive; you must

use capital D or capital L.

Byte count # can be from 0 to 32767,

default = 0.

The ASCII decimal # can be from 0 to

00255, default = 00000L.

Examples:

A 3-byte length = 3L.

A delimiter of ASCII 0A = 10D.

The response from the MLC includes

]

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

}

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

(for URL-encoded commands, use the
pipe character,

|

, instead)

= Space character

|

= Pipe (vertical bar) character

*

= Asterisk character (which is a command

character, not a variable)

E

= Escape key (hex 1B)

(for URL-encoded commands, use W

instead of Esc)

X!

= Specific port number or relay number (01-99)

Serial ports:

01 = COM1 port

02 = COM2 port

03 = COM3 port

Relay ports:

01 = Relay port 1

02 = Relay port 2

03 = Relay port 3

04 = Relay port 4

IR ports:

01 = IR port 1

02 = IR port 2

03 = IR port 3

04 = IR port 4

00 = reserved or all ports

N

Port numbers are two ASCII characters

(2 bytes). For example, port 1 is represented as
01 (hex 30 31).

X@

= Command data section.

N

For Web encoding only: data will be directed

to the specified port and must be encoded (URL
encoding) if it is non-alphanumeric. Change
any non-alphanumeric character (%, +,

|

,

}

, etc.) within the data section into the

corresponding hexadecimal equivalent, %xx,
where xx represents the two-character hex byte.
For example, a space (hex: 20) would be encoded
as

%20 (hex: 25 32 30) and a plus sign (hex: 2B)

would be encoded as

%2B or hex 25 32 42.

X#

= Greenwich Mean Time (GMT) offset value

(-12.00 to +14.00) represents the time

difference in hours and minutes

(+/-hh:mm) relative to Greenwich,

England. The leading zero is optional.

For example, 5:30 = 05:30. Do not use a

plus (+) sign if the GMT offset is positive.

X%

= On/off status

0 = off/disable (default for DHCP)

1 = on/enable

X^

= “Dirty” status:

0 = contents of RAM have been saved to

flash memory and it is ok to power off or

reset the unit

1 = RAM contents need to be saved to

flash memory

X1!

= Version (typically listed to two decimal

places, e.g., x.xx)

X1@

= IPL 250’s name. The name is a text string

of up to 24 characters drawn from the

alphabet (A-Z), digits (0-9), and minus
