I/O PAGES

This key gives access to setting up the DD1500's various inputs and outputs. Pressing F2
(I/O) displays this screen:
GPI
On the rear of the DD1500m is a 9-pin D-sub connector that offers three GPIs and five
GPOs (General Purpose Outputs). These may be used for a variety of purposes. For
example, the GPIs may be used with a very simple play only remote offering no more
than PLAY, RECORD and STOP for use without a DL1500 and where the DD1500 is
located using external timecode.
This screen allows you to set parameters relating to the GPIs. The parameters are:
GPI1/2/3
ACTIVE

These select which GPI you will affect.
You may select OFF, HIGH and LOW. When OFF, the GPI
has no function. When set to HIGH, the selected function
(see below) will become active when a +5V TTL signal is
received at the GPinput. When set to LOW, the selected
function will become active when a 0V TTL signal is
received.
Here you may assign a range of DD1500 functions to the
GPIs. These include:
PLAY - When a TTL pulse is received, the DD1500 will start
playback.
STOP - When a TTL pulse is received, playback will stop.
FAST FORWARD - When a TTL pulse is received, the
DD1500 will fast forward.

rewind.

DD1500 will play from the selected IN point to the selected
OUT point.
