7. Configuration
– DIP switches
The Mac Plus settings can be adjusted in two ways:
• By means of DIP switches;
• Via the MasterBus network (with a remote-control panel, or a PC with MasterAdjust software
connected via a USB Interface); see chapter 9 and 10.
This chapter only describes the DIP switch settings.
Note:
DIP switch settings overrule MasterBus settings. If DIP switches are not in their default
setting, the corresponding MasterBus setting is grayed out.
CAUTION!
Incorrect settings of the Mac Plus can cause serious damage to your batteries and/or the
connected load! Adjustments of settings may be undertaken by authorized personnel only!
Use a small screwdriver to carefully set the required
settings. You may need to remove the MasterBus
cables (or Terminator) to be able to access the DIP
switches.
For an overview of the various DIP switch settings,
see the following three tables, where a 0 indicates
