will be down sampled by. Applies to both MJPEG and H.264

Ethernet video.

0, 1 = no downsample

2 = 2x2 downsample

4 = 4x4 downsample

NOTE: Down Sample 4 is not supported for MJPEG on SLA-

Set Ethernet Display Parameters (0x29))

0 = Default (1500/2000: 640x480 in NTSC mode,

720x576 in PAL mode; 3000:output size==input size)

1 = SD (1500/2000: 640x480 in NTSC mode, 720x576 in

PAL mode; 3000: 640x480)

2 = 720x572 (3000 only)

3 = 720p (1280x720)

4 = 720p cropped (960x720)

5 = 1080p (1920x1080)

6 = 1080p cropped (1440x1080)

SLA-2x00: only size 0 is valid

SLA-1500: size 0 always valid. Sizes 1, 2 are valid when Video

Format is set to H.264 (HD)

0x0040=Net1,0x0042=both, else the command will be ignored),

if not present, then applies to both

Set Network Parameters (0x1C)

Configure the network settings for the device. See also Discover Protocol. Some SightLine products

can support multiple physical/virtual network interface controllers; these can be itemized by their NIC

index. However, for most applications, there will be only 1 NIC (index 0).

IMPORTANT: For parameter changes to take effect, a board soft reset should be performed, by

issuing Save Parameters (0x25) and Reset (0x01) (Reset Type = 2, soft reset) messages.
