2.12 Hardware Configuration Settings
In the ACU-1000, there are two types of system and module configuration settings: Hardware
and Programming. Changing physical pots, jumpers, and switches on each module adjust
hardware settings. Programming the configuration items of each module can be set via the
HSP-2A Keypad or, more easily, through the use of the ACU Controller or WAIS Controller
Module Settings Screens.
In general, the hardware settings are done once at installation and need not be changed unless
the system configuration changes (for example, if a different radio is interfaced to the ACU-
1000 rear panel), while the configuration items are more likely to be changed after installation
to optimize system performance. This section explains all hardware configuration switch and
jumper settings for each of the modules in a system. See Sections 0 and 2.16 for a full
explanation of Programming Configuration Settings.
To access the potentiometers, jumpers and switches, use the Extender Card found in the
Accessory Kit. Remove the module needing adjustment and install the Extender Card in its
place. Insert the Extender Card with its connector on the right side of the card (the Extender
Card connector must be on the same side of the extender card as the module components are).
The Extender Card can’t be plugged into the Power Supply Module slot. All modules except
the power supply module can be "hot-plugged" (removed and re-inserted with the unit's power
on) without damage, but interruptions to unit operation may occur.
