INTRODUCTION
There are two models in the USB-844 MegaCastPlus
series:
The USB-844-BC USB Keyboard or USB Mouse Broadcaster-Multicaster connects either one USB keyboard or one USB
mouse to up to four PC’s simultaneously.
The USB-844-KM-BC connects both a keyboard and a mouse to up to four PC’s simultaneously.
In both units, the keyboard and/or mouse are routed simultaneously to all connected PC’s. Both models allow one hub
between the input devices and the Broadcaster-Multicaster. The hub may be external or built into the keyboard, but only one
device may be connected to the hub for the USB-844-BC and two devices for the USB-844-KM-BC.
Both models feature user-controlled Inversion Multicasting, where PC #1 is excluded from multicasting. Multicasting
remains active for PC’s 2 - 4.
Both keyboard/mouse Broadcaster models come with the VIP-210 power supply.
Note: The "MegaCast” does not come with USB connection cables. One cable per PC is needed. They may be ordered
from Vetra separately.
INSTALLATION
Before connecting PC's to the Broadcaster-Multicaster, make sure the Broadcaster is powered by its Power Supply!
The PC's may be powered or not when you connect them to the Broadcaster-Multicaster.
Keyboard or mouse may be connected to the Broadcaster at any time.
Do not power down the Broadcaster while any PC is connected to the Broadcaster!
There are three main steps to make the Broadcaster-Multicaster ready for use:
1. Power Up:
First, connect the power supply included with the Broadcaster-Multicaster to the Power Jack, marked “+5VDC IN”, on the
back panel of the Broadcaster. Note that the front panel “PWR ON” indicator on the Broadcaster is on. When powering up
or connecting the PC’s, note that the appropriate “PC STATUS” indicator on the front panel comes on.
2. Connect PC's to Broadcaster unit:
For both the USB-844-BC and USB-844-KM-BC: Connect any available USB input on the PC's to the Broadcaster using
USB A-B cables. Connect PC #1's USB port to the back panel connector of the Broadcaster marked "PC1". Connect USB
ports of PC’s 2 - 4 to the back panel connectors marked "PC2" - “PC4”. The Broadcaster-Multicaster will operate with less
than all four PC's connected.
