Hi, i'm with some problems about sintax RS232 for the receiver AVR 4310CI

PC RJ45> GC-100-6 (RS232)> Denon receiver

using iTest and sending to the GC-100-6 i try these commands Power on:

Literal Mode:
PWON
PWON\0x0D
PWON\0x0A\0x0D

Mixed Mode:
PWON|0D
PWON|0D
PWON\0x0D|0D
PWON\0x0A\0x0D|0D


No one of these tryies got sucess.

PS. i Tryied using hercules software to recognize the port COMx from GC-100-6 but not sucess too...

PPS. Connecting PC via usb to serial adapter in the receiver, i can receive the codes in Hercules sotware when i interact (example, increase volume manually) - but i can't send the exat same codes via hercules, using ascii method and all.

Hope someone had these problems to help me,

Thanks.

Doesn't the 4310 have a network port?
Can't you just send the commands directly to port 23 on that and skip the global cache completely?

Denon does not require linefeeds, only carriage returns. 0x0D.

You may want to try \x0d or \x0D as well. Apologies as I don't have globalcache docs in front of me.

Lyndel is right. Looks like in iTest you need "/x" "\x" "0x" or "|", so you are probably sending incorrect data to the receiver when using "\0x" as the "\" is likely being sent to the hardware. A good way to check what you are sending is to disconnect the RS232 cable from the unit and short Tx and Rx together to see what you receive after testing your command.
