Aphex 1788 Addendum

July 1999
This addendum to your 1788 User's Manual contains the following information:

• Updated pin-out information for the MIDI connector

• Updated information for the RS-232/422 connector

• Operating information on the new DISPLAY BRIGHTNESS adjust function

Section 3.8b (update to Section 3.8)
The correct pin-out for the MIDI connectors is as follows:
Only the MIDI Out and MIDI Thru Ports connect Pin #2 to Ground.
Section 3.9b (update to Section .3.9)
We have changed the labeling on the back panel to facilitate the use of a PC (using our propri-
etary software) or the 1788-R to remotely control a Model 1788 or a group of Model 1788s.
