CONNECTING TO AN RS-485 CONTROLLED MACHINE OR CONTROLLER
7.3
Connect 3 wires from the detachable terminal block of the VS-3000 marked RS-485 to the RS-485
connector of the controlled device or controller. The order of the wires should be retained (1 to 1, 2 to
2, etc.)
CONNECTION TO A REMOTE DRY CONTACT CONTROLLING DEVICE
7.4
The 8 dry contacts may be attached to the 9 pin screw terminal connector. They may be magnetic dry
contacts often used in security applications, or they may be simple pushbuttons. Attach one end of
such contact to the corresponding number, and the other end to the GND pin.
The function of these dry contacts is fully user-programmable, and they may be turned OFF or ON in
the controller's setup. If turned ON, each contact recalls one of the eight programmable setups that are
saved in the controller memory. For multi-switch configuration, each such setup consists of a series
of two numbers – the number of the switcher, and the number of the setup that is saved in that
switcher memory. For a single switcher configuration, these dry contacts are similar in function to the
LOAD keys, but more flexible in programmability.
See more about this feature in "MENU – setup ALL units".
Using this feature, a single dry-contact, or one click of a pushbutton, can fully reconfigure a
system having up to 15 different Kramer switchers.

CONNECTING THE KEYBOARD EXTENSION

7.5
The In and Out keys are expandable. You can add an unlimited number of simple pushbuttons (up to a
distance of 100m) to the existing keys, using the 18-pin screw terminal connector on the rear panel. To
do this attach one end of the pushbutton to the corresponding number, and the other end to the In or
Out (for selecting the INPUTS or OUTPUTS connections.)
In the controller's setup it is possible to turn these keys ON or OFF. Note that the EXTERNAL keys
always work for the current switcher (the switcher which is indicated in the right-hand, small,
LCD).

USING THE VS-3000

Turning on the VS-3000

8.1
The VS-3000 should only be turned on after all connections are completed, and all connected devices
have been turned on. Do not attempt to connect or disconnect any signals to the VS-3000 while it is
turned on. Pressing the toggle switch on the far-left front panel to the up position turns on the VS-3000.
In the up position, the toggle switch glows.

Using the Front Panel Controls

8.2
The front panel of the VS-3000 was designed to be simple to operate, to accomplish the basic functions
of selecting an input source and output device.

KRAMER ELECTRONICS, LTD.
- Enter the INPUTs and OUTPUTs to be connected.
- For matrices, use both IN and OUT keys.
- For switchers (only one output) use only IN keys.
- When there are more than 16 INPUTs and OUTPUTs, the keyboard automatically
reverts to the "DECIMAL MODE", ie. keys 1-9 retain their meaning, key 10
becomes "0", and keys 11-16 are not used. To enter a number greater than 9, use
two keystrokes; to enter a number less than 10, first press 0, and then the required
key 1-9 (alternatively, press key 1-9 followed by ENTER).
- Used in the same way as it is in most KRAMER switchers.
