Introduction

www.ti.com
Introduction
This user’s guide describes the setup and operation of the TPS2384 HPA109 evaluation module (EVM).
Information and instruction presented throughout this document assumes user familiarity with the
TPS2384 and with the IEEE 802.3af Specification for Power Over Ethernet.
3
Hardware Overview
The HPA109 EVM features the TPS2384 made by Texas Instruments. This EVM can be configured as an
endpoint power sourcing equipment (PSE) or as a midspan PSE. Four-input and four-output RJ-45
connectors are provided to connect directly to an Ethernet cable.
According to the IEEE 802.3af specification, the PSE can apply power over the data lines or over the
spare lines on the Ethernet cable. The HPA109 EVM has been designed with jumpers for applying power
in either configuration.
The HPA109 EVM is designed such that the TPS2384 device can operate in either Auto Mode or Power
Management Mode. A graphical user interface (GUI) has also been developed to read and write to the
TPS2384 internal registers using the I2C interface.

EVM Operation
4.1
Operation
An external 48-V power supply connected to J3 pin 1 (positive) and J3 pin 3 (negative) is required. JV1 is
installed at the factory to apply the 48 volts coming out of the TPS2490 hot-swap controller to the
TPS2384 device. JP2 and JP3 also are installed at the factory to give the user the capability to use the S1
reset switch. Depressing S1 generates a logic low signal to the PORB input of the TPS2384 which resets
all internal state machines and registers.
The JMS1 jumper is also installed at the factory between pin 1 and pin 2. This sets the Mode Select (MS)
to Auto Mode. In Auto Mode, the TPS2384 automatically discovers, classifies, and powers up IEEE
802.3af-compliant powered devices (PD). Power is applied to the Ethernet port on either the spare pairs or
on the data lines of the RJ-45 connector. The TPS2384 EVM has jumper blocks that allow the user to
configure the method in which power is applied to the PD. Table 1 can help the user to set the appropriate
jumpers depending on the desired power delivery configuration. Although the table shows only the
connections for the P1_OUT1 connector, the information applies to all four output RJ-45 connectors.

While operating in Auto Mode, the I2C interface provided on the TPS2384 EVM can be used to monitor the
internal TPS2384 registers. Information such as detection status, port status, classification status, and
fault information is available over the I2C interface.
In Power Management Mode, the I2C interface can be used to manually power up and control the ports.
For a complete description of Power Management Mode functions, see the TPS2384 data sheet
(SLUS634).

I C Interface
The I2C interface on the TPS2384 EVM can be used to read and write to the TPS2384 internal registers.
For simplicity, an EVM available from Texas Instruments, the EV2400, can be used to connect the USB
port of a personal computer (PC) to the I2C interface of the TPS2384 EVM. A graphical user interface
(GUI) also has been developed specifically for the TPS2384 EVM. Section 5 of this document describes
the connections and operation of the TPS2384 GUI.
For I2C operation, an external 3.3-V supply must be connected to J3 pin 4 and referenced to J3 pin 3, or
J6 must be installed. Also, the jumpers JSDA_OUT1, JSDA_IN1, and JSCL1 must be installed.
Ensure that S2 address select switch is set for I2C binary address of 00001 (S2-1 closed and S2-2, S2-3,
S2-4, and S2-5 open).

TPS2384 Graphical User Interface Operation
This section describes the setup and operation of the TPS2384 GUI for the HPA109 evaluation module.
Two files, TPS2384EVM and TPS2384EVM.exe, must be downloaded from the TI Web site. These files
are located at http://focus.ti.com/docs/toolsw/folders/print/tps2384evm.html#supportsoftware. Click on the
word Zip beneath Product Description, Software Support at this location.
5.1
EV2400 Software
The EV2400 software is available for download from the TI Web site at the following location:
http://focus.ti.com/docs/toolsw/folders/print/EV2400.html
5.2
Connecting the PC to the EV2400
Using a standard USB cable, connect the USB port of the PC to the USB port of the EV2400.
5.3
Connecting the EV2400 to the HPA109 EVM
Using the wiring assembly provided with the EV2400, connect one end to the I2C port of the EV2400.
Connect the other end to the I2C interface connector of the HPA109 EVM as follows:
• Red wire to J1 pin 1
• White wire to J1 pin 3
• Brown wire to J1 pin 5
• Black wire to J1 pin 8
5.4
Starting the GUI
After installing all the necessary files for both the EV2400 and the HPA109, start the TPS2384 GUI by
executing the TPS2384EVM.exe file.
5.5
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.

In Auto Mode, only the read registers within the TPS2384 device are accessible.
Figure 1. Screen Shot of TPS2384 GUI – Enable Auto Read Selected
5.6
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. In order 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.
