9. ABOUT DURATION BETWEEN MESSAGES
The duration required from the time the host system issues a command until the EL4001 issues a
response data is about 100 to 300ms.
Execution of 01: Remote (keystrokes unacceptable) command in the local/remote select command (SM)
involves sending a response data as a result of switching from one screen to another. Hence, a duration
of about 3 seconds is required in this case.
It requires about 20ms for the EL4001 to issue a response until being ready to receive the next command.
If it is desired to issue a series of commands from the host computer, provide this time duration before
you issue subsequent command.
