E2PROG User Guide
ແນະນຳ
E2PROG is an application for configuring, serialising, and testing serial communications functionality in an FT8U100 system. The application maintains data that describes USB devices and formats it so that it can be programmed into EEROM. Configurable parameters include Vendor ID (VID), Product ID (PID), device description, and manufacturer name.
ການເລີ່ມຕົ້ນ
This section describes how to use E2PROG to program your first device.
When E2PROG is run for the first time, its display appears as follows :-
E2PROG is in Edit mode which means that the user must enter data in the edit fields. Nothing else is possible since all menu items (except Exit) and all buttons on the Toolbar are disabled. Fill in the fields moving between them using the Tab key. When all fields have been filled in the display looks like :-
Click on the Advanced Setup option that has become enabled on the Toolbar, or via the Device menu, to run the Advanced Setup dialog. Select appropriate settings for Options and Embedded Ports and click OK.
E2PROG has now accepted the device data and enables the Save option on the Toolbar and in the Device menu.
Review the data entered (mistakes can still be corrected at this stage), then click Save. E2PROG saves the device data and changes to Program mode. New options are made available as indicated by the buttons enabled on the Toolbar.
Select Program to write to the EEROM, and the serial number generated by E2PROG for the device is displayed in the log window.
Congratulations, your device has now been programmed.

This section describes the format of the edit fields.
ຜູ້ຜະລິດ
E2PROG User Guide
This is an alphanumeric field of length >= 2. Note that the combined length of the Manufacturer and Description fields must be <= 38.
ID ຜູ້ຜະລິດ
This is an alphanumeric field of length 2. Allocated by FTDI, it is used as the first two characters of the serial number.
ID ຜູ້ຂາຍ
The manufacturer’s VID is a hexadecimal field of length 4.
ID ຜະລິດຕະພັນ
The PID is a hexadecimal field of length 4. Allocated by the Manufacturer, and interpreted as a base ID for a device with embedded PS/2 and serial ports. PS/2 PID is Product ID+1, and Serial PID is Product ID+2.
ລາຍລະອຽດ
This is an alphanumeric field. Note that the combined length of the Manufacturer and Description fields must be <= 38.
Plug and Play Option
Default setting is checked which means enabled. Disable this option if plug and play enumeration is not available on the device. If in doubt use the default setting.
Embedded Ports
Default settings are not checked which means the ports are not embedded. Check the appropriate boxes if your device has embedded ports.
Toolbar Functions
This section describes the functions available on the Toolbar.
ໃໝ່
Input new device data. The user must fill in the Manufacturer, Manufacturer ID, Vendor ID, Prduct ID, and Description fields, run the Advanced Setup dialog, and save the device data. E2PROG guides the user in the following manner. The application mode is set to Edit, edit fields are cleared, and all functions (except Cancel) are disabled on the Toolbar. When all edit fields have been filled in, the Advanced Setup function is enabled, and after the Advanced Setup dialog has been run, the Save function is enabled. When the device data has been saved, E2PROG returns to Program mode as indicated on the status bar.
At any time before the new device data has been saved, the user can cancel by selecting the Cancel Edit function. In this case, E2PROG returns to Program mode and the previous device data is re-loaded.
ເປີດ
Retrieve device data. Data from previous devices can be restored by running the Device Selection dialog. 
To retrieve the device data, select the required device and click OK. The edit fields now contain the retrieved data.
E2PROG is still in Program mode, and is ready to use the retrieved data to program the device.
ບັນທຶກ
Save the current device data. The current data is saved and E2PROG returns to Program mode.
ການຕັ້ງຄ່າຂັ້ນສູງ
Display the Advanced Setup dialog. This allows the user to display and/or set Options including Plug and Play Enabled and the Embedded Ports mask.
ຍົກເລີກການແກ້ໄຂ
Cancel the current editing session. The current data is lost, E2PROG returns to Program mode, and the previous device data is re-loaded.
ໂຄງການ
Program the device. E2PROG generates a serial number, formats it together with the current device data and writes it to EEROM.
ການທົດສອບ
Test the device. The test results are displayed in the log window in the following format:-
ຜູ້ຜະລິດ: FTDI
Device ID: VID_0403&PID_8372
Description: USB Serial Converter
Serial Number: FTHXDTGA
CTS Test …………………………….PASS
DSR Test ……………………………. PASS
CD Test ……………………………. PASS
RI Test ……………………………. PASS
Rx/Tx at 300 Baud ……………………………. PASS
Rx/Tx at 115200 Baud ……………………………. PASS
DEVICE PASSED
Of course, failures are indicated with the string “FAIL”.
ຟັງຊັນເພີ່ມເຕີມ
This section describes the additional functions available on the Device menu.
Test Modem
Test the device. This function must be used by modem developers instead of the Toolbar function Test.
ອ່ານ
Read the contents of EEROM and display it in hexadecimal format in the log window. 
ລົບ
Erase the contents of EEROM. Displays a status message if successful.
ຂໍ້ຄວາມຜິດພາດ
This section describes the error messages displayed by E2PROG. Error messages are displayed in the Error dialog.
Click OK to remove the Error dialog.
Failed to open device
E2PROG is unable to find the device probably because it has not been connected.
Failed to open device for erase
E2PROG has failed to erase EEROM.
Failed to write device
E2PROG writes data to EEROM, then reads it back to confirm that the EEROM has been programmed properly. This error signifies that the confirm check has failed.
