User Instructions for the USB-882 Series "MegaMux"™
Keyboard, Mouse, and Video Multiplexer

INTRODUCTION

The USB-882 "MegaMux"™ KVM Splitter/Multiplexers allows two USB Workstations, each comprised of a keyboard, mouse, and (for some models - see below) one or two monitors to share access to one PC with only one workstation being active at a time. The USB-882-KM and USB-882-KM-KS models will handle keyboard and mouse only while the USB-882-KMV and USB-882-KMV-KS models add the capability of one monitor to each workstation. The USB-882-KMV2 and USB-882-KMV2- KS models allow the use of Dual video monitors at each workstation. The -KS models allow a fixed (for security purposes, with key removal) selection of a workstation. Please note that with the above models the monitor(s) at both workstations will be showing the same image(s) at all times.

INSTALLATION

1. Connect the Multiplexer to the PC.

(a) Use the USB Type A-B cables, supplied with the system, to connect one of the PC's USB ports to the USB Type B connector of the Multiplexer marked "TO PC". This finishes the connection to the PC for the USB-882-KM and USB-882-KM-KS models.

(b) For the USB-882-KMV, USB-882-KMV-KS, USB-882-KMV2, and USB-882-KMV2-KS models, connect the HDD15 male/female video extension cable to the PC's female video port(s) and the other end to the Multiplexer's male connector marked "TO PC MON". For the -KMV2 models connect the HDD15 male/female video extension cable(s) to the PC's female video port(s) and the other end to the Multiplexer's male connectors marked "TO PC MON A" and "TO PC MON B".

2. Connect Workstations to the Multiplexer:

(a) Use the normal keyboard cable to connect to one of the USB Type A connectors on the backpanel of the Multiplexer
marked "STA-1 IN". Use the normal mouse cable to connect to the female connector on the backpanel marked "STA-1 IN".
(b) Connect the video monitor to the Multiplexer's backpanel 15-pin HDD connector marked "STA-1 MON". For the -KMV2 models, connect the monitors to "STA-1 MON A" and "STA-1 MON B"

(c) Repeat the above steps for Workstation #2.

OPERATION

1. Power Up Sequence

All USB-882 Splitter/Multiplexers are powered by an external wall plug-in supply, the VIP-210 (+5Vdc 2A reg. 110 - 240 Vac 50 - 60 Hz). First plug the power output plug of this external supply into the mating jack on the front panel of the Transmitter marked "+5VDC IN", and only then plug the supply into a suitable AC power source. Since the Splitter/Multiplexers have no separate power on/off switch, it is recommended that the power supply be connected to an AC power source that has a power on/off switch.

When the PC is powered up, you may observe random selection of the "ACTIVE STATION" leds on the front panel of the Splitter/Multiplexer for a few seconds. This is normal. The Splitter/Multiplexer is initializing each of the input devices. The order and final selected station depends on the response time of each device.

2. Workstation Selection (not available on the -KS Models)

To switch from one Workstation to another there must be a 3 - 5 second delay between keyboard and or mouse inputs from one Workstation before the Multiplexer recognizes keyboard and/or mouse inputs of the next Workstation. Note that the front panel "ACTIVE STATION" LEDs of the Multiplexer will switch to the Workstation currently being used. They are both off when input from both stations is allowed. As soon as input from one workstation is detected, the LED for the station lights, and input from the other station is locked out, until there is 3 - 5 secs of inactivity from the currently active station.

3. Lock and Release (not available on the -KS Models)

Either Workstation has the option of locking out the other Workstation for uninterrupted input to the PC. To accomplish this the user must first be the current ACTIVE STATION. Then, by pressing and releasing the Left Shift key three times the other Workstation's keyboard and mouse inputs will be locked out, but the monitor will be viewing the same image. To release this feature, the same Workstation that activated the lock out must press and release the Right Shift key three times. This will set the Multiplexer back to the 3 - 5 second delay between Workstations.

4. Key Switch Selection, -KS Models only

The key switch option of the Multiplexer allows lockout-tagout of a Workstation with key removal. The operator selects which Workstation (1 or 2) is to be active. The other Workstation is locked out from communication with the PC. There is no active selection through keyboard and/or mouse inputs as mentioned above. To select a Workstation, you must use the key.
