Help with DirecTV HR21P rs-232

I'm having a little trouble communicating with a DirecTV HR21P receiver via rs-232. This particular receiver has an actual serial port for control, as opposed to using the USB-to-serial adapter method.

I am using the HR21P with an NI-4100. When I attempt to issue commands to the HR21P via telnet and the SEND_STRING command, I see the TX/RX lights light up, but the receiver doesn't respond at all. Does anyone have a example SEND_STRING command for the HR21P (or similar) that I could use to double check my formatting?

I'm a new AMX programmer, so any help is appreciated. Thanks.

    Have you verified that the cable is the correct pinout for the device?
    Why don't you post the code so that we may look at it

    I've tried both of these.
    SEND_STRING 5001:7:1,"'$FA','$81'"
    SEND_STRING 5001:7:1,"'$FA,$81'"

    have you set the baud rate for the device?

    Data_Event[Sat]
    {
    Online:
    {
    Send_Command Data.Device,"'SET BAUD 9600,N,8,1'"
    }
    }

    // Try this... You are using single quotes around the hex bytes, that is not correct. Double quotes on the outside is all you need.

    SEND_STRING 5001:7:1,"$FA,$81"

    Got it guys, had neglected to include the:
    Data_Event[Sat]
    {
    Online:
    {
    Send_Command Data.Device,"'SET BAUD 9600,N,8,1'"
    }
    }

    ondrovic mentioned. Plus, SEND_STRING 5001:7:1,"$FA,$81" as AMXJeff suggested, worked great.

    Thanks!
