The SerialGhost Wi-Fi (SerialGhost Pro Wi-Fi) may be configured through the file CONFIG.TXT, placed in the flash drive root folder. Use any text editor to prepare such a configuration file, containing the following text:


Copy this file to the root folder in flash drive mode. The new configuration will be loaded on next power-up.

The following list presents the most common configuration options. All variable and value strings are case insensitive.

Baudrate sets the baud rate in bits per second of the monitored serial bus. Range is 300 bps to 115,200 bps. Default value is 9600.

Bits sets the number of bits per transfer of the monitored serial bus. Possible values are 5, 6, 7, 8. Default value is 8.

Parity sets the parity bit type of the monitored serial bus. Possible values are No, Even, Odd, Space, Mark. Default value is No.

StopBits sets the number of stop bits per transfer of the monitored serial bus. Possible values are 1, 1.5, 2. Default is 1.

Timestamping configures the built-in time- and date-stamping module. Allowed values are Yes (timestamping enable) and No (timestamping disabled). Default is Yes.

TimestampInterval sets the interval of serial bus inactivity in seconds, that will trigger a new time-stamp being logged. Range is 1 second to 9999 seconds. Default value is 10.

DisableLogging allows to disable logging. Allowed values are Yes (logging disabled) and No (logging enabled). Default value is No.

Password sets the 3-letter password for remote access over TCP/IP (for example using KL Tools). Any three-letter combination is allowed (sequence and case are irrelevant). Default value is KBS.

LogMode sets the logging mode. Possible values are Bin (data is logged as binary data), Hex (data is logged as hexadecimal numbers), Dec (data is logged as decimal numbers). Default value is Bin.

Separator sets the separator character between data values in logging mode Dec/Hex. Possible values are None, Space, Comma, Tab, Newline. Default is Space.

LogStream configures which serial streams are to be logged. Possible values are Both (both RX and TX get logged), Rx (only Rx is logged), Tx (only Tx is logged). Default is Both. If the mode is set to Both, the [1] and [2] markers will be used to differentiate between streams.

UsbMode allows to switching between flash drive mode and Virtual COM mode (Pro version only). Allowed values are Flash (flash drive mode) and Com (Virtual COM mode). Default value is Flash.A full list of parameters is available in section Configuration files.

Recording dataRecord mode is the default mode of operation for the SerialGhost Wi-Fi (SerialGhost Pro WiFi) data logger. In record mode, the device will silently monitor the bidirectional data flow on the serial bus and store the captured data on the internal flash drive in file LOG.TXT.

The SerialGhost must first be configured to the appropriate serial bus parameters, such as baud rate. Refer to section Configuration for detailed instructions.

Installation of the SerialGhost Keylogger in record mode is quick and easy, no software or drivers are required. Simply plug it in-line on the serial bus, using the DB-9 connector. The device may be powered from a standard USB port, using the supplied cable. Alternatively, an external +5V DC (min. 200 mA) power supply may be used to power the device through the microUSB port (cell phone chargers with USB connectors are well suited for this).

Viewing recorded dataOnce serial data has been recorded, it may be retrieved on any computer with a USB port. This is done by switching to flash drive mode. Take the supplied USB cable and connect it to the micro-USB port on the logger’s side. Connect the USB cable to a free USB port using the supplied red USB Key.

After a few seconds, the SerialGhost Wi-Fi (SerialGhost Pro Wi-Fi) will automatically get detected as a mass storage device, and pop up as a removable drive. The operating system will use the standard built-in mass storage driver (MS Windows in the following examples).

Depending on the drive letters available, the device will be visible as a new drive, for example F:. Use the systems file manager to browse this disk (for example Explorer).

The removable disk will contain the file LOG.TXT with a text log of all captured data. The data is stored in the same format as appearing on the serial bus, without any encoding. The upstream data (TX) and downstream data (RX) will be differentiated by the markers [1] and [2] interleaved in the log file. The SerialGhost will also interleave time-stamps. The file LOG.TXT can be viewed and searched with any text editor, such as Notepad or MS Word.

Switching back to record mode can be achieved by a safe software removal of the flash disk. Use the systems standard disk removal procedure. For MS Windows, left-click on the Safe Removal icon in the system tray and select the appropriate drive. Then reconnect the SerialGhost to the USB port, however without the supplied USB Key.

To get the most out of the SerialGhost, install the supplied application KL Tools. Go to section Using KL Tools to find out more.
