Cheetah USB Hub
4
Connect the Hub to the Host PC
The USB204B should be
connected directly a host PC’s
USB port. The hub only has to be
plugged into the host USB
connector to operate. Up to 4
other hubs can then be daisy-
chained in series from the first
hub.
1. Prepare standard shielded 90
Ω
USB cable with Type-A
(upstream) and Type-B
(downstream) plugs on each
end. The maximum cable
length is 5 meters (16.4 feet).
2. Connect the Type-A end of the cable to the host PC’s USB
port and the Type-B end to the hub.
3. Check that the hub’s downstream port power LED is green.
If this LED is off, then follow the advice in the
“Troubleshooting” section to diagnose the problem.
Connect Devices to the Hub
Before connecting devices to
the hub, check the
USB interface
requirements.
Devices can be
“low-power” or
“high-power,”
with “low-speed” or “full-speed” signaling. The USB204B is a
high-power, full-speed device. Refer to instructions supplied
with each USB device for their individual operation.
1. Prepare standard 90
Ω
USB cable with Type-A (upstream)
and Type-B (downstream) plugs on each end.
Low-Speed Devices: Shielded or unshielded 90
Ω
USB cable
Full-Speed Devices: Shielded 90
Ω
USB cable
Cable Length:
Maximum 3 m (9.8 ft) for unshielded cable
Maximum 5 m (16.4 ft) for shielded cable
2. Connect the Type-A end of the cable to one of the hub’s
downstream ports and the Type-B end to the USB device.
3. Check that the hub’s downstream port power (green) LED
is on. If this LED is off, then follow the advice in the
