I am using a Universal Remote MSC-400 to send serial commands to a Denon 4806CI.

When I embed the Serial command as part of a Macro group, the Denon doesnt respond the first time I send the command but responds the second time.
I dont understand why I have to send the command (eg: to wake up from standby or to go to standby) twice.. Sending a single command to the Denon appears to work ok, just not so when I execute a group of commands (not all of which are directed to the Denon)

Other components that I am controlling do not exhibit this issue even using Macro groups.

your feedback appreciated. I also posted this query inthe Universal Remote area of the Forums.
