7.1 Introduction
The I
are then transferred to the host PC if demanded, over a standard I
The following data can be monitored for the individual units connected to the I
1. Status of the unit.
2. Actual output voltage, output current and internal temperature of the unit.
3. Manufacturing related data (model, serial number, manufacturing date etc…).
7.1.1 Addressing (A0, A1, A2).
Three address lines allow up to eight FPS1000 units to be addressed on a single I
internally pulled-up to +5V by resistors. Addressing of a unit is achieved by hard-wiring an address line to the
-Sense to set it to "0" or leaving the address line open to set it to "1".
7.1.2 Serial clock
This line is clocked by the processor which controls the I
via a pull-up resistor of 2KΩ. The I
7.1.3 Serial dataThis line is a bidirectional data line. It should be connected to +5V
(referenced to -Sense) via a pull-up resistor of 2KΩ.
