ADIN1100 10BASE-T1L Ethernet PHY Evaluation Kit Media Converter to 10BASE-T with ADIN1200 Ethernet PHY

General Description

The EVAL-ADIN1100EBZ is a flexible platform enabling quick evaluation of ADIN1100, robust, low power 10BASE-T1L PHY. It provides 10Mbit per second Single Pair Ethernet (SPE) connections with devices over 1.7km of cable. The evaluation board offers two modes of operation for maximum flexibility. Connected to a PC via USB port, the full set of ADIN1100 register settings and features such as link quality monitoring and diagnostics can be accessed with the ADIN1100 Graphical User Interface software. Alternatively, the board can operate in stand-alone mode where it is configured by setting hardware configuration links and switches. Onboard LEDs provide status indication. The ADIN1100 data (MII, RMII and RGMII) and management (MDIO) interfaces are accessible on header connectors for easy connection to an external host controller. A small prototyping area and test points are provided for experimentation with alternative cable connection topologies including isolation transformers and/or power coupling inductors. The platform can perform as a 10BASE T1L to 10BASE-T media converter. This enables connection to other devices – demos or a custom prototypes – with a 10BASE-T1L Ethernet port and conversion of the data to standard Ethernet accessible via the RJ45 connector.

Hardware

Power Supplies

The EVAL-ADIN1100EBZ can be powered by a power supply with output voltage between 5 to 32V DC connected via the plug-in screw-terminal connector P1, or via the P2 barrel connector plug. Alternatively, the board can be powered from a host via its USB port, or by a USB charger connected to the micro-USB connector P401. The power supply source can be selected by link on J1 “BOARD PWR SELECTION”. Inserting link in position “USB” enables the board to receive power from USB connector. Inserting link in position “PWR+EXT+” enables the board to receive power from connectors P1 and P2. If both J1 “BOARD PWR SELECTION” “USB and “PWR+EXT+” links are inserted, there is a “diode or” implemented on the input of J1, and the supply with a higher voltage will supply the board. The power from the source is converted by a step-down converter U501 LT8619EDD#PBF to 3.3V, and with link inserted in position J2 “PWR 3.3V”. the 3.3V rail supplies all circuits on the board. The presence of 3.3V power is indicated by green LED1 “POWER”. The board power consumption depends on the mode of operation, with the maximum of approximately 0.5W.

10BASE-T1L Cable Connection

The 10BASE-T1L cable can be connected via pluggable screw-terminal block to connector P101. If more of the pluggable connectors are needed, for easy connecting / changing cables, additional connectors can be purchased from the vendor or distributors: Phoenix Contact, part number 1803581, “Pluggable Terminal Block, 3.81 mm, 3 Ways, 28AWG to 16AWG, 1.5 mm², Screw”.

Ground Connections

The demo board has an “Earth node”. We call it “Earth node” here – though this node may or may not be electrically connected to Earth ground. In a real device this node would be typically connected to the device metal housing / chassis. This Earth node can be connected as required in a wider demo system via “Earth” terminal of the power supply connector P1, or via exposed metal plating of 3 mounting holes in the corners of the board. (The 4th hole does not have metal plating, and also no Earth connection.) The shield of the 10BASE-T1L cable can be disconnected from this Earth node, connected directly, or connected via 4700pF capacitor (C104). The required connection is selected by relevant link position of J101. The 10BASE-T Earth connection and metal body of the RJ45 connector (P5) are connected directly to the Earth node. The local circuit ground, the external power supply (except the “Earth” terminal P1), and the USB connector are connected to the Earth node via approx. 2000pF capacitance and approx. 4.7M resistance. (!) Note: The EVAL-ADIN1100EBZhas been designed only as an Evaluation board. It has NOT been designed, and it has NOT been tested for electrical safety. Any equipment, device, wire, or cable connected to this demo must be already protected and safe to touch without danger of electric shock.

µC Modes Of Operation

The EVAL-ADIN1100EBZ can be used in various modes of operations implemented in the uC firmware. Up to 16 modes of operations can be selected by setting the 4 positions of the slide switch S402. The status of the switch is accepted (latched) after the board is powered up or reset. Therefore, to change the mode of operation, the board must be reset by pressing “RESET” button S400 or by applying power cycle after changing the position of the slide switch S501. The detailed description is in the relevant sections of this document.

Software

The EVAL-ADIN1100EBZ can be used as stand-alone board, with the firmware already programmed in the uC flash memory, the mode of operation set by mode switch, and status indicated by LEDs. There is no software needed for this stand-alone use case.
The demo can also be connected to a PC via USB port, the full set of ADIN1100 register settings and features such as link quality monitoring and diagnostics can be accessed with the ADIN1100 Graphical User Interface software, available from Analog Devices.
Alternatively, the ADIN1100 and ADIN1200 registers, 10BASE-T1L link status monitoring and some diagnostics can be accessed using a simple set of ASCII text commands and messages exchanged over the USB Com Port and a serial port terminal software.

Driver For USB COM Port

The EVAL-ADIN1100EBZ uses FTDI FT232 for the USB Com Port connectivity.
Please make sure that appropriate Virtual Com Port driver is included or installed on the host platform before connecting the EVAL-ADIN1100EBZ to that host via USB cable.

The drivers are available from FTDI, at the time of writing this document at https://ftdichip.com/drivers/vcp-drivers/.

COM Port And Terminal Settings

When the EVAL-ADIN1100EBZ is connected to the host, it will become available in the host system as a USB Com Port, and will be assigned a com port number. The number will depend on the system settings, on com port devices previously connected and assigned in the system, and on the FTDI driver settings.

The EVAL-ADIN1100EBZ uC firmware communicates over a standard UART interface, with settings:

Speed 115200 Bd., 1 Start Bit – 8 Data Bits – No Parity – 1 Stop Bit.

The protocol is based on ASCII text commands and messages. Each message and command are finished by <newline>. Each message sent from the firmware to the host is finished by both <CR> and <LF> characters. For the commands received from host the firmware expects the <newline> as character <CR> or <LF> or both <CR> and <LF>.

(To be sure and clear:
<CR> .. “carriage return”, ASCII code 0x0D, 13dec,
<LF> .. “line feed”, ASCII code 0x0A, 10dec.)

Terminal Software

The EVAL-ADIN1100EBZ firmware works with the common serial terminals. It has been tested on Windows platform with PuTTY, RealTerm, Termite and the old Hyperterminal.

Terminal Commands And Messages

(The examples here were captured using Compuphase Termite).

Initial Welcome Message

When the EVAL-ADIN1100EBZ is correctly connected, from the uC firmware and UART, via the USB Com Port, to the terminal software, the firmware sends after power or after pressing the board RESET button S501 an initial welcome message:

Status And Diagnostics

To see the status of the demo, use command “phystatus”, which will read and show the latest status of the ADIN1200 10BASE-T PHY and ADIN1100 10BASE-T1L PHY:

phystatus
ADIN1200 Link is Up,
ADIN1100 Link is Up, Master, 2.4 V
MSE -37.2 dB Rx 0, Err 0

To see a continuous update, use commands “start”:
start
OK
MSE -38.4 dB Rx 255, Err 0
MSE -38.6 dB Rx 256, Err 0
MSE -38.7 dB Rx 257, Err 0
MSE -38.4 dB Rx 257, Err 0
MSE -38.7 dB Rx 257, Err 0
stop
OK

The firmware will periodically, with period of approx. 1 second, send an update. The update in the present firmware version includes:

“MSE” – 10BASE-T1L Mean Square Error, which indicates link quality.
“Rx” – number of Ethernet frames received by PHY from 10BASE-T1L cable since the last board / firmware reset, or after use of command “clear”
“Err” – number of frames with error received since the last board / firmware reset, or after use of command “clear”

To stop the continuous update, use command “stop”. (Or reset the board.)

µC Firmware Update

The uC (U401 ADuCM4050) is programmed before shipping the demo board, and therefore there is no need to program it, unless a new version of firmware is available, and you want to update it on your board.
The present firmware version can be checked via USB Com Port and terminal software, it is displayed in the welcome message after board reset or in response to “info” command.
Firmware update is distributed as a compiled binary (.hex) file. The easiest way to program it to the uC is using the USB Com Port and CrossCore Serial Flash Programmer, available for free download from analog.com, presently:

https://www.analog.com/en/design-center/evaluation-hardware-and-software/software/crosscore-serial-flash-programmer.html#software-relatedsoftware

Figure 4. CrossCore Serial Flash Programmer.

USB Com Port driver (same as for using the terminal software) needs to be installed on the PC before connecting the board and using the CrossCore Serial Flash Programmer - see chapter “Driver for USB Com Port”.
When you have the driver and programmer software installed, and firmware update hex file ready, use the following steps:

Connect the board (P401) via micro-USB cable to your PC.
Start the CrossCore serial flash programmer software.
Set the programmer (also see Figure 4):
- Target: ADuCM302x
- Serial Port: COMx (USB Serial Port) – (the “x” port number is depending on your PC)
- Baudrate: 115200
- Action: Program
- (Second stage kernel is not applicable)
File to download - browse for the firmware file on your PC
On the demo board, simultaneously press and hold buttons S501 “RESET” and S401 “BOOT”. Release the RESET button first, followed by releasing the BOOT button. The on board microcontroller is in the programming state now, and the yellow / orange heart beat LED402 will stop blinking.
Click Start and the code should start to download with messages provided in the Status window and progress bar across the bottom of the window.NOTE: If you have been using a terminal program for communicating with the board, either disconnect it / release the com port, or stop the terminal program, otherwise you will see a message “Failed to open serial device”. A message “No autobaud response” most likely indicates that the uC is not in the programming state and you need to go back to step 5.
After programing, press & release RESET button.
