(2) CLOSED Enables the Motor Start Option. In this mode of
operation the drive will wait for a Start Unit Command
from the Host before starting the Motor.
OPEN The motor will start as soon as DC power is applied
to the unit.
(3) CLOSED Parity checking by the WREN 6HH is enabled.
(4) If the unit is not be terminated, remove terminator resistor
module SIPs. If installed, the TP jumper must be installed in
either Position 1 or Position 3 as indicated.

With jumper in Position 1, terminator power (+5V) is taken from WREN 6HH power connector. With jumper in Position 2, terminator power is supplied to the interface cable by the WREN 6 through an isolation diode and fuse network. With the jumper in Position 3, terminator power is taken from the interface cable Pin 26 through a fuse.
If the drive is not terminated, the TP jumper in position 1 need not
be installed.
(6) Factory use only (8,9) and (10) reserved jumper position.
(7) ON Entire drive is write protected.
(8) Jumper on enables delayed motor start (Motor Start jumper (2)
must be off). Motor start up is delayed 16 times drive ID number
in seconds; i.e., Drive 0 starts immediately, Drive 1 starts 16
seconds later, Drive 2 starts 16 seconds after Drive 1, etc.
No Motor Start command is needed to start drives with this
jumper on.

Note: Pins on the drive select and configuration select header are
provided to facilitate manual drive configuration. No devices other
than jumpers should be connected to these pins. Improper connection
to external devices (switches, connectors, etc.) could adversely
affect drive performance. Exact location of these pins and headers
may change without notice.
