Autopatch 1YDM? Newbie

Hello - I'm coming from an Extron switcher which was working without a hitch until it went belly up (tested RS232 - works). I got an Autopatch 1YDM via ebay (RGBHV) and have tried using the same code but just changing the protocol for the Autopatch which doesn't seem to work. I'm not sure if it's my code or the cable (NULL) that I am having an issue with.
Sample Code:

Original Extron:

PUSH [TOUCH_PANEL, 69] (* BUTTON 69 WAS PRESSED ON TOUCH_PANEL *)
{
SEND_COMMAND PANA_ST50, "'SP', COMPONENT_1"
{
SEND_STRING MATRIX,"'5*1!',$0D" (* CAMERA FRONT DOOR , COMPONENT 2 FAMILY RM*)
}
}

Adjusted code:

PUSH [TOUCH_PANEL, 69] (* BUTTON 69 WAS PRESSED ON TOUCH_PANEL *)
{
SEND_COMMAND PANA_ST50, "'SP', COMPONENT_1"
{
SEND_STRING MATRIX,"'CL1I5O1T'" (* CAMERA FRONT DOOR , COMPONENT 2 FAMILY RM*)
}
}

Any help would be much appreciated.

Thank You
