Command/Response Table for SIS Commands (continued)
Command
ASCII (Telnet)
(host to MLC)
URL Encoded (web)
(host to MLC)
Response
(MLC to host)
Additional Description
Serial port configuration and use
These commands apply to any port that uses RS-232 communication: both 1-way (output) and 2-way (bidirectional) RS-232 communication.
Send data string

RS
} X@
X!
= Specific port number (01-99):
1
= front panel Config (RS-232 host) port
2
= Display RS-232/IR (projector) port
3
= MLS port (slaved or auxiliary switcher
0
= reserved or all ports.
X@
= command data section (< 200 bytes).
X1&
= time in tens of ms for the MLC to wait
until receipt of the first response character
before terminating the current receive
operation (default =
10
= 100 ms, max. =
32767). The response includes leading zeros.
X2)
= time in tens of milliseconds (ms) for
the MLC to wait between characters being
received via a serial port before terminating
the current receive operation (default =
2
= 20 ms, max. =
32767
). The response
includes leading zeros.
X2!
= #L or #D. The letter parameter is case
sensitive (requires a capital “D” or capital “L”).
The response includes leading zeros.
X2!
:
L
indicates the length of the message to be
received.
D
indicates the delimiter value that ends the
response.
# = byte count (for L) or a single ASCII
character expressed in decimal form (for D).
Byte count # can be from
0
to
32767
,
default =
0
. The ASCII decimal delimiter #
value can be from
0
to
00255
, default =
0L
.
For #L, # is a regular ASCII (character)
numeral. If the length is 50 bytes, # =
50
.
For #D, # can be any character(s) or
number(s), but it is translated into decimal
format for use in the command.
Examples:
A 3-byte message length = 3L.
A delimiter of $ would be entered as
36D
(36 is the decimal equivalent of the dollar sign).
A delimiter of ASCII
0A
=
10D
(line feed).

NOTE:
*
X1&

X2)
*
X2!
is optional.
X1&
may be omitted only if
X2)
is also missing. If these three variables are not
specified, the default values are used. For this command,
X1&
and
X2)
must both a) equal zero,
b) be nonzero, or c) both be omitted.
NOTE:
For web encoding
for
X@
, convert non-alphanumeric characters to hex numbers. A space (hex =
20
) is
encoded as
%20
. A plus sign (hex = 2B) is encoded as
%2B
.
Example:
E
05*4*7*3L RS
}

W05%2A4%2A7%2A3L RS

NOTE:
The data string (
X@
) in this RS command is limited to 200 bytes.
NOTE:
Use the ASCII to decimal table below to convert the byte count number for
X2!
when using a delimiter (D).

ASCII to Decimal Conversion Table
To find the decimal equivalent of the ASCII character, add
the row heading and column heading numbers together.
LF = line feed
CR = carriage return (
}
)
Esc = escape
Del = delete
