Section 2. Installing Your PlexWriter

PlexWriter 48/24/48A Installation and Users Manual
To use CSEL, you must have:
•
A computer that supports CSEL.
•
A special CSEL cable for IDE.
NOTE: The IDE cable supplied by Plextor does not support CSEL. To use CSEL and
Cable Select, you’ll have to purchase a CSEL cable, or use one that may be supplied
with your CSEL-configured system.
Identifying Whether Your System Uses Cable Select
If you are unsure whether or not your system has a Cable Select cable installed,
either look at the cable or look at the jumpers on the CD-ROM drive. If any device is
jumpered as Cable Select, then both devices on that cable should be jumpered the
same.
Locating the Master Position on a Cable Select Cable
With Cable Select, Master and Slave are determined not by jumpers, but by the
connectors on the Cable Select cable. The connectors are identified as Master or
Slave.
Set the DMA Jumper
Your PlexWriter ships from the factory with no DMA jumper installed. (The pins are
empty.) The empty pins mean the drive is set to Ultra DMA. This setting should
work in most cases, so you don’t have to do anything more.
With some (generally older) personal computers that do not have an Ultra DMA IDE
chipset, the computer may “hang” or crash with the PlexWriter set to the default
Ultra DMA setting. If this happens, change the PlexWriter to Multiword DMA mode
by installing the DMA jumper across the two pins just to the left of the mode jumper
pins.
Figure 11. Add the DMA jumper if you need to change to Multiword DMA.
