The X10 IR codes you posted on Yahoo did not work
with the Neo and the X10 IR543 receiver.

However, the follow codes DO work; although, the
range is limited to about five feet. Below are
the IR codes for units 3, 5 and 6 as well as ON
and OFF.

Unit 3: 0 f 6c 3 5f 4e 2e 8e fe 3f 5f bc 16 62
21 56 61 95 15 62 21 56 61 95 7c 3

Unit 5: 0 f 6c 3 5f 4e 2e 8e fe 3f 5f bc 16 22

Unit 6: 0 f 6c 3 5f 4e 2e 8e fe 3f 5f bc 56 21
