Hello
I would like to control a Sony projector with a macro from a codec (RoomOS 11.15.1.0) via RS-232 (outbound).
The Power-On command is: "\xA9\x17\x2E\x00\x00\x00\x00\x3F\x9A" (all HEX) But the codec sends out the following: \xC2\xA9\x17\x2E\x00\x00\x00\x3F\xC2\x9A.
Why is there always a \xC2 before the \xA9 and \x9A?
Solved! Go to Solution.

Now I have written the command with double \\x and it works.:
I don't know if this is the normal HEX notation or a workaround.

Tested today with RoomOS 11.15.1.1 with the same problem. Here is a screenshot...

The command works via the xcommand and the projector switches on. Must be a firmware bug via the macro.

Same problem also in RoomOS 11.15.1.2

Still not resolved in RoomOS 11.15.1.3.
Let's hope for the next version...

Same problem also in RoomOS 11.15.1.5

Still no improvement in RoomOS 11.15.1.6.
As soon as Cisco has fixed the bug, I will get back to you with the RoomOS version.
I hope Cisco reads the API-Bug forum...

Here is the manual with the wrong description for HEX.
• Text (required): The text to send to the peripheral.
You can add special characters using “\” notation for special characters and “\x{ASCIIHEXCODE}”
for hex characters.
Example: To send a string ending with carriage return and new line, enter “Hello World\r\n” or
“Hello World\x0D\x0A”.
