any power or indicator LEDs on the Hub are on if you experience
problems.
FireWire Active Extension cables are also hubs, just with the cable
already attached. A FireWire Repeater is also another name for a
hub. Each connection between hubs can be a maximum of 4.5
meters (14.5 feet), but only the best quality cables will work
reliably at this distance. Verify that your computer to IF-FW/DM
MK
II connection works with the supplied cable before extending
the connection using hubs, this way you will know if a particular
hub or cable starts to cause problems.
FireWire Chipset Compatibility
1394a (FireWire 400) ports
The IF-FW/DM
MK
II is designed to work with 1394a, a.k.a.
FireWire 400, S400 or Sony i.LINK.
VIA chipsets are widely used and are a good match for the IF-
FW/DM
MK
II.
The IF-FW/DM
MK
II has been noted to perform badly with some
NEC and TI branded chipsets.
Check the TASCAM web site for any updates.
1394b (FireWire 800) ports
1394b, a.k.a. FireWire 800, S800 is a high-speed version of
FireWire 400 that is fully backwards compatible. The IF-FW/DM
MK
II will work with a standard cable or connector adapter from 9
pin (1394b) to 6 pin (IF-FW/DM
MK
II). In this case, the IF-
FW/DM
MK
II will still work at its own speed of FireWire 400.
When installing Windows XP Service Pack 2, there is a known
issue that the maximum speed of any 1394b ports is reduced to a
slow speed.
