How to use a telnet client to connect to a networked Tibbo device - WKB243331

OBJECTIVE or GOAL

Receive the raw data transmitted by a lab instrument through the connected Tibbo device. (The data is used to determine the correct Escape Sequence Receive string for use in Waters' Serial Device Support software.)

ENVIRONMENT

• A suitable telnet client is installed on a client PC; the client must be able to show the sent and received data in both hexadecimal characters and interpreted as ASCII characters
• The lab instrument is connected to a supported Tibbo device, and that device is on the network

PROCEDURE

• Using TibboTech IO Ninja:
  1. Start IO Ninja.
  2. Click the file menu \ New Session.
  3. Select TCP Connection and click OK.
  4. Click the Session menu \ Settings.
  5. Set the Remote address to the IP address of the Tibbo device.
  6. Set the Remote port (default) to the port number of the Tibbo device (typically port 1001).
  7. Click the Session menu \ Connect.
  8. If the device supports commands sent by serial port:
     1. Type the command into the transmit pane (lower half of the window).
     2. If the command requires a carriage return or linefeed, press Ctrl-Enter to add that character to the transmit pane.
     3. Click the Send button.
  9. If the device does not support commands sent by the serial port, press the required buttons on the instrument to "print" or "send" the data.
  10. The instrument's reply will appear in the IO Ninja window. The program will show the raw data in hexadecimal and the interpreted characters. Often there will be more hex characters shown than for the visible characters. The hex characters are often control characters and are used by the instrument to demarcate individual lines within the transmission and to end the transmission as a whole.
• Using PuTTy:
  1. Start PuTTy.
  2. Set the IP address of the Tibbo device into the Host Name field of the PuTTy Configuration window.
  3. Set the port number to the port number for the Tibbo device (typically 1001).
  4. Set the Connection Type to Other: Telnet.
  5. Click Open.
  6. If the device supports commands sent by serial port:
     1. Type the command into the PuTTy window.
     2. Press Enter.
  7. If the device does not support commands sent by the serial port, press the required buttons on the instrument to "print" or "send" the data.
  8. The instrument's reply will appear in the PuTTy window.
• Using Windows Telnet client:
  1. Install the Telnet client.
  2. Open a command prompt.
  3. Enter the command: telnet IPAddress Port
  4. Example:
     • ​​​​​​​telnet 10.105.134.72 1001
  5. ​​​​​​​If the device supports commands sent by serial port:
     1. Type the command into the telnet window.
     2. Press Enter.
  6. If the device does not support commands sent by the serial port, press the required buttons on the instrument to "print" or "send" the data.
  7. The instrument's reply will appear in the telnet window.
