AMP setting -- The AMP parameter “Block Transfer Capability” when
set to enabled, also enables the pass through feature. Once downloaded
to the control, this setting remains until either AMP is lost or changed.
Softkey -- This method is discussed below. It uses a softkey to
temporarily enable block transfers and DH+ pass through. This setting
remains in effect only until the next time power is cycled or the softkey
is pressed again turning the feature off. The softkey is not available
when the AMP setting is enabled.
Use the softkey to enable DH+ pass through as follows:
1. Press the {SYSTEM SUPORT} softkey.

2. Press the more {Ô} softkey.
The right most softkey will be the {PT ENABLE} softkey. This key
is only visible when the AMP parameter “Block Transfer Capability”
is set to disabled and PAL has enabled remote I/O using the $RMON
flag.
3. Press the {PT ENABLE} softkey to toggle between pass through
enabled and disable. When the softkey is shown in reverse video
block transfers and pass through is enabled. When the softkey is not
in reverse video block transfers and pass through is disabled.

Important: If you do not use block transfers and do use remote I/O single
transfers, keep in mind that when pass through is enabled the first word in
the remote I/O rack (both input and output) is not available to PAL. Refer
to the parameter “Adapter Start Module Group” for details. The warning
“CAUTION: 1ST DISCRETE RIO UNAVAIL TO PAL” is displayed
when pass through is enabled via softkey.
