SerialGhost Wi-Fi

Introduction

About the product

The SerialGhost Wi-Fi is a compact RS-232 and serial bus logger with a memory capacity of

2GB, that may be accessed locally as a USB Flash Drive, or remotely through Wireless LAN.

Bidirectional data flowing through the serial bus will be captured and stored on the internal

Flash Drive in a special file. This data may be retrieved by switching to Flash Drive mode,

giving instant access to all captured data. The Wireless LAN functionality allows receiving

logged data as E-mail reports, and on-demand via the local TCP/IP network. The SerialGhost

Wi-Fi also features a built-in time-stamping module and battery. This enables it to add time

and date information to the log file. Thanks to the internal battery, the time and date persist

even when the device is not powered. The SerialGhost Wi-Fi does not require any dedicated

software or drivers.

Features

Logs asynchronous serial transmission (RS-232 compatible)

Baud rates up to 115200 bps

Logs 2 streams simultaneously (RX and TX)

2 Gigabytes internal memory

Powered from a USB port, or external power supply

No software or drivers required, Windows, Linux, and Mac compatible

USB Flash Drive mode

Background connection to the Internet over a local Access Point

Automatic E-mail reports with recorded data

On-demand access at any time through TCP/IP

Support for WEP, WPA, and WPA-2 encryption

Time and date stamping

Built-in battery

Requirements

Asynchronous serial bus with RS-232 logic levels (+/-12V)

Operating system with USB Mass-Storage device support

5V DC power source (external power supply, or USB port)

Wi-Fi compliant Access Point coverage (WPA-2, WPA, WEP64/128, or open network)

Optionally MS Windows XP/Vista/7/8 (only for running KL Tools)

SerialGhost Wi-Fi

Quick Start

This section contains concise information on basic operation of the SerialGhost Wi-Fi. If you

need detailed instructions, please refer to sections Configuration, Recording data, and

Viewing recorded data.

Before you start, make sure you have the following information about the serial bus you want

to log data from:

Baud rate (bits per second)

Number of bits per transfer (usually 8)

Parity bit configuration (usually not used)

Number of stop bits per transfer (usually 1)

Step 1. Open a text editor (such as Notepad) and create a file named CONFIG.TXT. This file

will later be used to configure the device. Use the following template:

Baudrate=9600

Bits=8

Parity=None

StopBits=1

Replace Baudrate with the actual baud rate in bits per second of the serial bus you want to

log data from. Replace Bits with the number of bits per transfer (5…8). Provide the parity

check using one of the following strings: None, Even, Odd, Space, or Mark. Replace StopBits

with the number of stop bits per transfer (1, 1.5, or 2).

Finally, save the configuration file as CONFIG.TXT.

SerialGhost Wi-Fi

Step 2. Connect the serial logger and enable Flash Drive mode.

Take the supplied USB cable and connect it to the mini-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 will automatically get detected as a mass storage

device, and pop up as a removable drive.

Step 3. Copy the configuration file CONFIG.TXT to the logger’s Flash Drive.

Then, safely remove the device, and disconnect it from the USB port. Disconnect the USB

cable as well.

Step 4. To start logging, connect the logger in-line on a serial bus, powering the device

through the mini USB port.

The device may be powered from a standard USB port. Do not use the red USB key.

Alternatively, an external +5V DC (min. 200 mA) power supply may be used to power the

device through the mini-USB port (cell phone chargers with USB connectors are well suited

for this).

Step 5. To retrieve the logged data, enable Flash Drive mode using the red USB Key, just

like in step 2. A removable drive will pop-up, containing the file LOG.TXT with recorded data.

The upstream data (TX) and downstream data (RX) will be differentiated by the markers [1]

and [2] interleaved in the log file.

SerialGhost Wi-Fi

Step 6. To configure the Wireless LAN connection, make sure you have the following data

about the Wi-Fi network the device will operate in:

WLAN Access Point ID (SSID)

WLAN encryption type (WPA-2, WPA, WEP64/128, or open network)

WLAN encryption password

Make sure you also have an E-mail address the logger can send reports to.

Open a text editor (such as Notepad) and create a file named WIFI.TXT. This file will later be

used to configure the device. Use the following template:

WiFiNetwork=MyNetwork

WiFiPassword=MyPassword

WiFiEncryption=WPA2

Recipient=john@smith.com

Replace MyNetwork with the Access Point ID (SSID). Replace MyPassword with the WLAN

password. Provide the encryption type using one of the following strings: WPA2, WPA,

WEP64, WEP128, or None. Provide the E-mail address you would like to receive reports to

after the Recipient string. Make sure you provide all strings in a case-sensitive manner.

Finally, save the configuration file as WIFI.TXT.

Step 7. Enable Flash Drive mode, as in step 5, and copy the configuration file WIFI.TXT to

the Flash Drive.

SerialGhost Wi-Fi

Then, safely remove the device, and disconnect it from the USB port.

Step 8. On the next power-up, the logger will automatically connect to the Access Point

defined in WIFI.TXT, and send an E-mail report to the specified recipient address every hour.

Besides logged data, the report will contain Access Point information, IP configuration, and

time-stamps.

SerialGhost Wi-Fi

Step 9. If E-mail reporting is not enough, you can take full control over the device from any

computer in your Local Area Network. Install the supplied application KL Tools, add the logger

to the list by its IP number, and explore the available features.

Using KL Tools you can communicate with multiple SerialGhosts, allowing creating entire

networks of wireless data loggers. This solution is particularly recommended for monitoring

several devices in a system with a large number of devices using serial buses, such as RS-

232.

To read more on KL Tools, jump to section Remote access.

SerialGhost Wi-Fi

Configuration

The SerialGhost 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:

Baudrate=9600

Bits=8

Parity=None

StopBits=1

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 None, Even,

Odd, Space, Mark. Default value is None.

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, available in the

SerialGhost TimeKeeper only. Allowed values are Yes (timestamping enable) and No

(timestamping disabled). Default is Yes.
