Serial Communication, cont’d

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)

NThis 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.

NThe SM command will send a default X4& is not found.e-mail message if file

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.

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 %)
