3.2 The Terminating Resistor
Since hard disks can be connected to the controller in a
daisy-chain fashion, the drives have a resistor called a
terminating resistor.
The resistor can either be removed
(Seagate, Micropolis and Miniscribe drives) or disabled
(NEe 5146) so you can turn the terminator on and off,
depending on the configuration of your computer.
To
locate the terminating resistor of your drive, refer to
Figures 1A through 1E.
The last drive connected to the
daisy-chain cable must have its terminating resistor installed.
If the controller has two drives connected to it, the drive
attached to the middle of the daisy-chain cable must have its
terminating resistor removed.
Removing the Terminating Resistor (Seagate, Micropolis
and Miniscribe drives):
Removing the resistor from the drive attached to the middle
connector of the daisy-chain cable is a very easy process.
Use a small screwdriver, and gently pry the resistor off the
hard disk drive. Do not throw the terminating resistor away, if
you ever move the drive, you may need to reinstall the
terminating resistor.
For this reason, put the terminating
resistor in a safe place.
Note the following figures to see whether to install or
remove the terminating resistor.
