14.4 Software

Problem	Remedy
Software version is not updated	Carefully remove the switcher cover and identify the EPROM chip that is located
	in the middle of the main board, marked by a white sticker. Remove the chip
	with the proper tools and insert the new EPROM carefully, observing proper
	polarity.

14.5 Control

	4.	Confirm that all DIP switches on the switcher have been set properly. Keep in
2000 control panel
		mind that if you are only controlling one switcher on a specific port, that
		switcher must be assigned the ID of “ 1” .
	5.	If controlling more than one switcher on a single port, all switchers must be
		of the same type and power to all switchers must be on.
	6.	Confirm that you have the proper machine number and control port selected
		on the VS-2000. For instance, if you are controlling a single machine on port
	7.	1, then both of these should be set to “ 1” .
		Confirm that you have the proper switcher type selected on the VS-2000. If
		not, go back to Section 12.2.3 of this manual “ Using the VS-2000 Remote
		Control Panel” .
No control of switcher from PC	1.	Confirm the wiring of the connecting cable. This pin configuration may be
software		found in Section 11 “ Connecting to a PC or Compatible System” . Cable
		length should not exceed 25 feet.
	2.	Confirm that all DIP switches on the switcher have been set properly. Keep in
		mind that if you are only controlling one switcher on a specific port, that
		switcher must be assigned the ID of “ 1” .
	3.	If controlling more than one switcher on a single port, all switchers must be
		of the same type and power to all switchers must be on.
	4.	Confirm that the baud rate of your computer COM port is set to the same as
		that of your switcher (9600-Baud). Confirm that the proper COM port is
		selected in the control software.
	5.	Confirm that bi-directional communication is enabled on all switchers. Please
		refer to Section 9 “ The Configuration Switches jumpers and trimmers” for
		proper configuration for your switcher.
	6.	With custom software, do not send multiple commands at the same time. The
		switcher must complete one command before receiving another.
	7.	Confirm that the computer you are using supports true RS-232C protocol.
		Computers, such as the Apple Macintosh do not!
