HARDWARE SETUP

Pushbutton Switches

There are two pushbutton 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. When holding down

this switch while powering up, the system will go into bootstrap mode. You can then 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 revert to the factory default settings. To use this

function, you need to hold down the switch while powering up the system. This will stop the

controller from loading your settings from the EEPROM and will load the factory default settings

instead. Although your settings are not loaded once you power up holding the RE-INIT switch,

they 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 Ring. In order to get

the controller to communicate over the ring, you need to download the

backup settings file available from Delta Tau’s website

(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; the B connector plugs into

the J1-USB port. Up-to-date USB drivers are always included in the latest software packages

from Delta Tau’s Web site (www.deltatau.com).

NOTE:

Since the USB connector will connect the ground on the

controller and computer together, make sure the computer and

controller have the same voltage ground, i.e., they are connected

to the same power line.
