1. GENERAL INFORMATION
1.1 Introduction
The Ethernet to Automotive Ethernet Gigabit Converter, AX141520, has both Ethernet and Automotive
Ethernet Physical Layer transceivers (1000BASE-T and 1000BASE-T1 PHYs) that are used to achieve bi-
directional communication. The converter supports configuration via RS232 to update the speed
(100/1000Mbps) as well as to set the Automotive Ethernet PHY to Master/Slave mode. The AX141520 does
not store any packets and does not modify or filter any packets.
By default, both PHYs (Ethernet and the Automotive Ethernet) communicate at a speed of 1000Mbps, and
the Automotive Ethernet is configured to work in Slave mode. Status LEDs provide information on Power,
Connection Link, and Activity.
Power LED will be ON as soon as power is supplied to the converter. The Power LED is used to verify
whether power is supplied to the converter. If the proper power supply level is connected to the converter,
the Power LED will be ON; indicating the converter is ON. The AX141520 is continuously monitoring the
status of Link and Activity by reading the registers of Ethernet PHYs and will show the real-time update of
Ethernet and Automotive Ethernet Link and Activity on Link and Activity LEDs, respectively.

3. CONFIGURATION USING RS-232
RS-232 configuration is password-protected and can be accessed through Tera Term or other serial
terminals. Tera Term Serial Port setup is shown below.
Figure 3 Tera Term: Serial port setup
Default configuration menu includes Project details like Project Name, Version number, Release Date, Part
Number, and Serial Number. The menu has 8 options as attached in the picture below. To access any of
the 8 options the one-time password is “AX141520”.

To view or change the configuration, please enter the password: “AX141520”.

3.1 Show Configuration Parameter
Press ‘1’ to see the Configuration parameters. This option will show Serial Number, Converter Mode,
Converter Speed, and Log Timing.
If the converter Mode is “Master”, it shows that Automotive Ethernet PHY is configured to work as Master. If
the converter Mode is “Slave”, it shows that Automotive Ethernet PHY is configured to work as Slave.
Speed shows the speed of both PHYs.
Log Timing is used to see the Power and (Ethernet and Automotive Ethernet) Link logs over RS-232. Logs
are used for debugging and testing purposes. Log Timing does not affect the Converter’s working and
Master-Slave or Speed configuration of PHYs.

3.2 Change Configuration Parameters
Press ‘2’ to change the configuration parameters. This option gives the choice to change Serial Number,
Mode, Speed, and Log Timing. Enter the name of the parameter that needs to be changed other than Serial
Number. The option to change the Serial Number is not available for field updates.
Enter the name from the list given on the Tera term window. i.e., “Mode”, “Speed”, or “LogTiming”. Any
string entered other than given on the Tera Term window will be discarded by the Converter, as the string is
case sensitive. i.e., to change Speed, typing “speed” will have no effect as the converter is expecting for the
string “Speed”. Changing the Speed will change the Speed of both Ethernet and Automotive Ethernet
PHYs.
Type “Mode” to change the mode. Press ‘1’ to configure the Automotive Ethernet PHY in Slave mode or ‘2’
for Master mode. Changing the Mode will change the Mode of Automotive Ethernet PHY only, as normal
Ethernet PHY has Auto-negotiation enabled to negotiate the Mode.
Log Timing could be configured to have a value between 1 Second to 10 Seconds.
The Master/Slave and Speed settings will be saved. So, after reset or power cycle, the converter will have
the last configured Speed, Mode, and Log Timing.
Enter the name of the parameter: “Enter string Mode to change Mode”. To change the Speed or Log Timing
Follow the same method. As shown in the picture below.
Figure 7 Change Parameters "Master to Slave"

UMAX141520 Version 1B 10-19
3.3 Set Default Configuration Parameters
Press ‘3’ to set the default configuration parameters. This option will set the Mode and Speed to Slave and
1000Mbps respectively, as the default mode is Slave mode and default speed is 1000 Mbps.
The log timing will be also changed to the default value, which is 1 Second.
The configuration settings will be saved. So, after reset or power cycle, the converter will have the last
configured Speed, Mode, and Log Timing.
3.4 Erase EEPROM
Press ‘9’ to Erase EEPROM. Erasing the EEPROM will erase the Firmware Flags and Firmware
Configurations (Mode/Slave and Log Timing) stored in EEPROM. So, in the next power cycle, the firmware
will store default Configuration parameters and Firmware Flags.
This is useful while doing the Firmware Version update, to erase the old version number stored in EEPROM
and save the new version number.
3.5 Temperature of Ethernet PHYs
Press ‘c’.to read the internal temperature of both the PHYs in Celsius.
