3-6
X6( = The number of seconds before timeout
on the IP connection:
(min = 1; max = 65000; default =
30 = 300 seconds). If no data is received
during the timeout period, the Ethernet
connection will be closed. Each step =
10 seconds. Applicable only when
connected via Ethernet. When connected
via RS-232 only the global timeout
commands apply (current returns E13).
The response is returned with leading
zeros.
X7) = Number (as optional parameter) that
will get inserted into email message if
.eml file has an embedded server-side
include “<!--#echo var=”WCR|” -->”
(ESC CR command with no params).
Use 0 as placeholder if optional X4& is
used but X7) isn’t needed.
X7! = Input selection: 1 to 4
X7@ = Input selection: 2 or 4
X7# = Input Video Format:
1 = Composite
2 = S-video
3 = RGBcvS
4 = YUVi
5 = YUVp
6 = RGB scaled
7 = RGB pass through
8 = Auto detect/YUV Auto
9 = SDI
X7$ = H Start: 0 to 127 for video inputs;
0 to 255 for RGB and YUVp inputs.
X7% = V Start: 0 to 93 for video inputs; 0 to 255
for RGB and YUVp inputs.
X7^ = Pixel phase: 1 to 31
X7& = Total pixel (+/- 255 of the default value)
X7* = Active pixel (+/- 100 of the default value
for video and +/- 127 for RGB)
X7( = Active line (+/- 127 of the default value)
X8) = 0 or 1
X8! = Input Standard:
0 = None
1 = NTSC 3.58
2 = PAL
3 = NTSC 4.43
4 = SECAM
X8@ = internal temperature (in degree Celsius)
X8$ = Text label / Preset name:
Up to 16 characters
X8% = Picture adjustment: 0 to 127
X8^ = H and V position (values depend on
current output rate)
X8& = H and V size (values depend on current
output rate)
X8* = Zoom (100 to 200%)
X8( = Pan (values depend on current output
rate and zoom %)
X3& = Event buffer offset
(range: 0 to MaxBufferSize)
X3* = Event data size
b = bit
B = byte (8 bits)
S = short (16 bits)
L = long (32 bits)
N This parameter is case sensitive.
X3(= Event data to write
X4! = Reading Password:
RS-232 connections responds with
password. IP connections responds with 4
asterisk (****) if password exists and empty
if not, instead of actual password.
X4$ = Number of bytes to read
(range = 1-24 max)
X4% = E-mail event number (1 - 64 max). The
response is returned as 2-digits with
leading zeros.
X4^ = E-mail recipient’s address
X4& = Name of e-mail file to be sent
First line of the file is the subject. The rest
is the body of the e-mail.
N The SM command will send a default
e-mail message if file X4& is not found.
X4* = Event status fields
event_type
event_state
event_paused
error_status
RcvBuff_startptr
RcvBuff_endptr
DataBuffA_startptr
DataBuffA_endptr
DataBuffB_startptr
DataBuffB_startptr
X4( = Default name: a combination of the model
name and the last 3 character pairs of the
unit’s MAC address (e.g., DVS-304-00-023D)
X5! = Extended-security (Password) levels:
1 – 10. The response is returned as 2
digits with a leading zero.
X5@ = Connection’s security level:
0 = anonymous
1 – 10=extended security levels 1 thru 10
11 = user
12 = administrator
X5$ = ASCII digit(s) representing the numeric
value of the data element read from the
event buffer (leading zeros are suppressed).
X6$ = Broadcast repetition rate in seconds
(0 – 255 max; default = 0 = clear)
The response is returned with leading zeros.
1 – 11 = entry without password goes to
the level specified (if an admin password
exists). The response as returned a 2-digits
with a leading zero.
