Busy Reply Setting (ADVANCED[3]Busy Reply)
The input terminals of AN-LS1 can be RS-232C (CONTROLLER) and 10BASE-T. Respective input
terminals can be connected to separate devices, but in actual if one of the terminals is being used the
other terminal cannot be used.
When data is being transmitted using one input terminal, it is not possible to use the other input
terminal until communication using the first terminal is completed.
This setting is for operation of the input terminal that cannot be used.
It is possible to select whether ERR is returned or nothing is returned when a return (CR:0x0d) code
is sent to the terminal that cannot be used.

Input Hold Time Setting (ADVANCED[4]Input Hold Time)
The input terminals of AN-LS1 can be RS-232C (CONTROLLER) and 10BASE-T. Respective input
terminals can be connected to separate devices, but while one is in use, the other is put into an
unusable state, and it is possible to protect communication content. The minimum requirement for the
Input Hold Time is an interval from transmission of data until a response returned from a projector is
complete.
When a response is not returned from the projector within a set time, it is possible to reliably receive
a response by extending the Input Hold Time.
Also when the time of protection for one device is too long, there may be cases where the other device
cannot establish communication as desired. In this case, set Input Hold Time to be small so that both
communications can be carried out without any problem.
Setting can be carried out in 100 ms units, from 100 ms to 40000 ms.
