Grove camera

I bought this:
seeedstudio.com/depot/grove- … p-945.html

Hooked up serial TX,RX, 5v, Gnd. When I power it on I see on PC terminal:
.Ctrl infr exist
.User-defined sensor
.625
.Init end

But it does not respond to any commands. That means I hooked up the 4 wires correctly, not backwards. That means I have the correct baud rate. I tried sending:
0x56 0x00 0x26 0x00
and
0x56 0x00 0x36 0x01 0x00
nothing in response. Not the above text, Assembled a packet in X-CTU.

What can I test next? Please help!

Hi there,

Do you use anything connected to the computer on? TX, RX is connected reversal? Can you give some photo or screenshot?

Give us more detail.

Best regards,
