TELEM-GW6 Manual

Introduction

Data Concentrator TELEM-GW6 (GW6-e) is designed for use in electrical networks as an communication concentrator.
Main applications of GW6 are:

• Data acquisition and control of regional and national electricity utilities in SCADA systems for remote control and substation automation.
• Cross-referencing of data exchange protocols
• Creating transparent TCP/IP to serial channels for remote connections to various equipment (for remote handling of various equipment)
• Comprehensive integration of different devices
• Full scale data exchange between substation devices and substation control system including setting values, measurement values, registered fault parameter values, changes of state with associated time markings etc.

Firmware update

NB! Before updating to new firmware read the setup from your device, and make a backup.
Loading firmware via SSH

• Copy the compressed (*.7z) firmware update file (provided by Martem AS) to your computer
• Set up SSH connection with GW6 if you have not done this before in this session or changed users. Login as martem. If you have not changed the password then default password is provided by Martem AS
• Press the “Upd.” button next to SSH settings
• Press the pick button and select the copied update file (file will be automatically unpacked to temporary folder)
• Press the “Update” button, the update process starts
• Wait until the device resumes to its normal operation state (“Run” LED will start slow blinking again)
• Firmware update is complete. Check if firmware update was successful.

Checking results of the firmware update operation:

• Press “Get Result” button
• Check the state of installed files at the last part of the file. If the state of update files is OK - firmware update was successful.

Loading firmware through Secure Digital (SD) Memory Card slot:

• Connect Secure Digital (SD) Memory Card to your computer
• Extract the compressed firmware update file (provided by Martem AS) to your SD Memory Card
• Disconnect the card from your computer
• Insert the card to TELEM-GW6 SD Memory Card slot

:* SD Memory Card slot is located at the back of the device

• Perform reset operation to TELEM-GW6 device
• Wait until the device resumes to it’s normal operation state
• Firmware update is complete. Remove the SD Memory Card and check if firmware update was successful

Checking results of the firmware update operation:

• Connect the SD Memory Card to your computer
• Open the folder you extracted earlier
• Check if the file “res.txt” is present and open it
• Check the state of installed files at the last part of the file

:*If the state of update files is OK - firmware update was successful

Default setup, indication

RESET: Switch RESET to ON state and then back to OFF state for Reset operation
DFT. SET: To apply default setup:

1. Switch DFT. SET to ON state

• Alert indication LED starts blinking within 5 seconds
• Alert indication LED will blink for 2 seconds

1. Switch DFT. SET back to OFF state when the alert indication LED is blinking to apply default setup

If DFT. SET is switched back to OFF state when the alert indication LED is not blinking, default setup will NOT be applied

For operation
Green LED – Blinking green indicates that the program is running
Red LED – Failure

For communication
Green LED at GPS port – blinking indicates the existence of GPS time synchronization.
