TIPS

•“ERR” is returned when there is no relevant command or when the command cannot be used in the current state of the monitor.

•If communication has not been established for reasons such as a bad connection between the PC and monitor, nothing is returned (not even ERR).

•If no monitor has been assigned the designated ID number (e.g. if the command IDSL0002 is used, but no monitor with ID number: 2 is found), no response is returned.

If execution of the command is taking some time

(0DH, 0AH)

When the following commands are used, “WAIT” is returned. In this case, a value will be returned if you wait a while. Do not send any command during this period.

No ID number is attached to WAIT response.

•Commands which return WAIT:

1.When repeater control is used

2.When an IDSL or IDLK command is used

3.When one of the following commands is used: RSET, INPS, ASNC, WIDE, EMAG, EPOS, PXSL, POWR,

AGIN, MWIN, MWIP, MWPP, ESTG

When control via RS-232C is locked (to prevent use) using the operation lock function (see page 24)

Communication interval

•After OK or ERR is returned, you must send the following commands.

To set a timeout for the command response, specify 10 seconds or longer.

•Provide an interval of 100 ms or more between the command response and the transmission of the next command.

VOLM0020

OK

Interval of 100 ms or more

INPS0001

WAIT

OK

Advanced operation

This section explains commands for daisy chain connection. The basic communication procedure is the same as in the “One-to-one connection with a PC” section.

ID numbers

You can assign a unique ID number to each monitor (see page 19). This allows you to control a particular monitor in a daisy chain of monitors.

You can assign ID numbers either from the menu screen (using the remote control) or from the PC using RS-232C cable.

[Example]

ID number: 1 ID number: 2 ID number: 3 ID number: 4

If monitors are connected as shown above, you can execute commands like “Set the volume of the monitor with ID 4 to 20”.

When controlling monitors linked in a daisy chain by designating ID numbers, you should basically avoid any duplication of ID numbers.

ID numbers do not have to be assigned in ascending order starting from the PC. They can also be connected as shown below.

[Example]

ID number: 3 ID number: 2 ID number: 4 ID number: 1
