Engineer installed current GUI, went through all the operating procedures, resulting in this:
GUI Operation for TPS2384 Auto Mode (JMS1 Jumper Connected Between Pin 1 and Pin 2)
On the TPS2384 GUI, click on the Start access button. The Enable Auto Read button should be selected (this is the default mode). As a point of reference, a screen shot of the TPS2384 GUI is shown in Figure 1. The GUI register numbers shown on the GUI screen correspond to the register numbers on the TPS2384 data sheet.
• Register 0 shows the Chip ID and Chip Revision.
• Register 100 shows the classification and port status for each of the four ports. This register also shows the Discovery Fail and Function Done for each port.
• Register 101 shows the Detect Status for each of the four ports along with the AtoD Active status of each port.
• Registers 110 to 1101 show the raw data and converted data for resistance, voltage, and current. Temperature data is not sampled in Auto Mode. Temperature data is only available in Power Management Mode.
Engineer replies: I have done everything as above, however the GUI shows all (0) zeros, etc. It’s like the GUI is not receiving anything. The message does say “USB to I2C interface found” also “error code 10” appears after I hit the Start access pushbutton (beforehand it says “error code ?”).
Next, engineer was asked to try this:
GUI Operation for TPS2384 Power Management Mode (JMS1 Jumper Connected Between Pin 2 and Pin 3)
After starting the TPS2384 GUI, click on the Start access button. This allows the GUI to report the TPS2384 status resisters. To control the TPS2384 write registers, depress the Disable Auto Read button. Select the desired function in Register 10 by selecting the pulldown arrow button under the desired port. The default function is shown as Disable (see Figure 2). All the functions appearing when the pulldown arrow button is selected correspond to the functions shown in the TPS2384 data sheet for the individual Port Write Control Register. For a description of each of the functions, see the Power Management Mode section of the TPS2384 data sheet (SLUS634).
After selecting the desired function, depress the corresponding port number on the left side of the GUI in the register 10 section. This writes the command into the TPS2384 register and thereby performs that operation. To view the status, depress the Read button on the top left of the GUI. This is a one-time event that takes a snapshot of the TPS2384 status registers. For a continuous update of the status registers, depress the Enable Auto Read button on the GUI. And let me know what the result is (it will give a clue to what is not correct…), as you did with Error10 (I assume after the first set of steps), please include error codes and messages. With that I can find out what might be wrong.
Engineer replies: Same result as GUI shows all (0) zeros, etc and “error code 10” appears.
Please advise . . .
