For further support, contact your POS software provider.

Terminal Management System (TMS) parameter settings

  1. Duplicate transaction check – to prevent transactions being duplicated when there is a break in communications between the EFTPOS terminal and the POS, we recommend flags that may be enabled in the terminal called 'check duplicate transactions'. This flag is not enabled by default. Your POS must increment the POS reference number every transfer this setting to be of value. If you would like this setting enabled, please contact your Relationship Manager or the Merchant Enquiries team on 1800 230 177 (available 24/7).
  2. Cloud connections – there is an inbuilt 10 second delay after the transaction has been approved on the EFTPOS terminal to the POS. If your cloud connection is stable this value can be set to zero which will improve the transaction speed performance. The parameter is called 'dialogue time out'.

EFTPOS terminal software

The recommendation is for your terminal to be operating on the latest software which is 8.42b or higher. When your terminal restarts the software version is displayed on the screen. While CommBank endeavours to update your version automatically, due to a number of factors not all terminals are updated to this version. Commbank can facilitate the swap out of your terminal to the latest software version. If you require the latest software update or need to swap out your terminal, please contact your Relationship Manager or the Merchant Enquiries team on 1800 230 177 (available 24/7).

Physical terminal set up

Avoid movement at the EFTPOS terminal if possible as cables cannot be stressed. Ensure your terminal is only paired to the one base.

To avoid any issues, take care to ensure you place the EFTPOS terminal is back on the base it was installed with. The EFTPOS terminal will not function correctly if it is placed on a different base. For further support see Essential Move5000 POS Stand Guide
