If it’s 4 channels input card, the input card channel id is 0,1,2,3; if it’s 8 channels input card, the input card channel id is 0,1,2,3,4,5,6,7 \[vt6cutleft(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)Cut\_Pixel(CR)]\ Cut the left pixels of input signal \[vt6cutright(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)Cut\_Pixel(CR)]\ Cut the right pixels of input signal \[vt6cutup(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)Cut\_Pixel(CR)]\ Cut the upper pixels of input signal \[vt6cutdown(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)Cut\_Pixel(CR)]\ Cut the bottom pixels of input signal ### 2.11\[vt6inputmode(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)Signal\_type(CR)] Setup input signal type Signal Type: 1=VGA 2=video 3=Ypbpr 4=DVI 5=HDMI 2.12 \[setgroup(SP)Group\_ID(SP)Start\_output\_channel\_ID(SP)End\_output\_channel\_ID(CR)] Setup output group, one number is one channel, start from 0. The group setting must be based on output card, one output card uses 2 group id is not supported currently. For example: setgroup(SP)1(SP)0(SP)8 (CR)// 1 is group ID, 0 is start channel, 8 is end channel ### 2.13 \[rstgroup(CR)] Delete all groups ### 2.14 \[Setgroupname(SP)Group\_ID(SP)Group\_Name(CR)] Setup group name ### 2.15 OSD Settings Input card slot id start from 0. If it’s 4 channels input card, the input card channel id is 0,1,2,3; if it’s 8 channels input card, the input card channel id is 0,1,2,3,4,5,6,7 \[openosd(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(CR)] Open OSD function \[osdpos(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)x/2(SP)y/2(CR)]\ Setup OSD potision, x is horizontal pixel and y is vertical pixel. The instruction value is half of actual value. For example, if you want display OSD at the position 200\*300 for input card slot 1 and input card channel 2, the command is osdpos 1 2 100 150 \[osdcolor(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)R(SP)G(SP)B(CR)]\ Setup OSD color, for example, red is 255 0 0, green is 0 255 0 \[osd(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(SP)Content(CR)]\ Setup OSD content, support chinese, english, number and character \[closeosd(SP)Input\_card\_slot\_ID(SP)Input\_card\_channel\_ID(CR)]\ Close OSD function on one input channel of one input card slot ### 2.16\[setgxy(SP)group\_ID(SP)New\_output\_channel\_ID(SP)x1(SP)y1(SP)x2(SP)y2(CR)] Output channel replacement, the replacement must be setup in same group currently For example: setgxy(SP)1(SP)9(SP)1921(SP)0(SP)3840(SP)1080(CR)// 1 is group ID, 9 is new output channel ID, 1921*0 is the start position of channel 2 and 3840*1080 is the end position of channel 1. This insturction will replace channel 2 by channel 9. ![](https://3680659020-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Mag_nOsvVHzGPFURFWd%2F-McgdLmG3FGxDheDA9V_%2F-McgnmNuzn8piuHoDzlu%2F1111.jpg?alt=media\&token=cbf4900d-ae37-4f38-beee-9eb331934c19)
