5. Command transmission timing

5.1. Standby state
1). For all mode with the standby configuration of "network on"
The first command can be sent anytime and the subsequent commands should be sent after receiving a colon from the
projector.
2). Other than 1)
PWR ON can be sent any time.
5.2. Power on state
A command should be sent after receiving the colon of the previous command from the projector. The following is an
exception. When the PWR OFF command is sent to 7800/7850/8300/9300 with the standby configuration of "network off",
the subsequent command should be sent 10 seconds after the colon is received.
In case that you can not wait for the colon and send a command after receiving it, instead send a command after the
execution time listed in the following table.
