RS232 and HEX

McNeill

How can I assign a hex command string to a variable or constant and the transmit it? I tried putting this statement under the define_constant section:
dvProjVidInput = "$02,$41,$44,$5A,$5A,$3B,$49,$49,$53,$3A,$56,$49,$44,$03"

And then send it with:

SEND_STRING dvProj, dvProjvidinput

I am seeing $02,$41,$44,$5A,$5A,$3B,$49,$49,$53,$3A,$56,$49,$44,$03 out the comm port but if I do this:

SEND_STRING dvProj, "$02,$41,$44,$5A,$5A,$3B,$49,$49,$53,$3A,$56,$49,$44,$03"

it works... What am I missing?

dvProjVidInput = "$02,$41,$44,$5A,$5A,$3B,$49,$49,$53,$3A,$56,$49,$ 44,$03"

Should be as

 ProjVidInput[] ={$02,$41,$44,$5A,$5A,$3B,$49,$49,$53,$3A,$56,$49,$44,$03}

Send_String dvProj, ProjVidInput

Define_Constant is fine for this

How is variable defined? Here is an example of an integer array

INTEGER CAM1_COMMANDS[][]=
{
     {$FF,$01,$88,$88,$25,$35,$6B}		// UP
    ,{$FF,$01,$88,$90,$25,$35,$73}		// DOWN
    ,{$FF,$01,$88,$84,$35,$25,$67}		// LEFT
    ,{$FF,$01,$88,$82,$35,$25,$65}		// RIGHT
    ,{$FF,$01,$88,$C0,$25,$00,$6E}		// TELE Wide
    ,{$FF,$01,$88,$A0,$25,$00,$4E}		// TELE Zoom
    ,{$FF,$01,$00,$00,$00,$00,$01}		// STOP
}
}

SWITCH(nSOURCE[nTP_NUM])
	{
	    CASE 25:
	    {
		IF( BUTTON.INPUT.CHANNEL=50 OR				// tele wide and tele zoom need a stop to make press and hold work
		    BUTTON.INPUT.CHANNEL=51)
		{
		    SEND_STRING dvEquipPelco,"CAM1_COMMANDS[BUTTON.INPUT.CHANNEL-45]"
		    SEND_STRING dvEquipPelco,"CAM1_COMMANDS[7]"
		}
	    }

Thanks Guys!! I knew it was something simple on my part that was amiss.
