Turbo PMAC2 Realtime Express Controller
Hardware Setup
8
Push-button Switches
There are two push-button switches located at the bottom of the unit next to the 24V power
supply input. These buttons are accessible for reinitializing the board back to factory default
settings and loading new firmware revisions.
FW LOAD switch
The FW LOAD switch is used to download new firmware to the controller. In order to use this
switch, you need to hold the switch pressed while powering up the system. This will cause the
system to go to bootstrap mode, after which you can use Delta Tau’s Executive software to
download the new firmware to the controller.
RE-INIT switch
The RE-INIT switch will cause the controller to reset to factory default settings. To use this
function, you need to hold down the switch while powering up the system. This will stop the
controller to load your settings from the EEPROM and load factory default settings instead.
Although your settings is not loaded once you power up holding the RE-INIT switch, your
settings are still available in the EEPROM, until you overwrite them with a SAVE command.
Caution:
Loading the factory default settings for this specific controller will stop the
normal functioning of the system over the MACRO and/or Realtime
Express Ring. To get the controller to communicate over the ring, you
need to download the backup settings file available from Delta Tau’s
website at http://www.deltatau.com.
Connections
USB Connection, J1
This connector is used in conjunction with USB A-B cable, which can be purchased from any
computer store. The A connector is connected to a PC or hub device and the B connector plugs
into the J1-USB port. USB drivers are always included in the latest software packages from Delta
Tau’s website at http://www.deltatau.com.
Note:
Since the USB connector will connect the ground on the
controller and computer together, make sure that computer and
the controller have the same voltage ground, i.e., that they are
connected to the same power line.
