Unable To start the samsung scan process

Hello, when I start scanning units using Intesis MAPS, I got an error message ''Unable to start the Samsung scan process"
Your help would be helpful to me.

Samsung unit needs to be configured to accept “Central Control”.

To properly communicate with the Intesis, take into account following considerations:

  • Samsung NASA AC network allows for both automatic and manual addressing. Manual addressing of both indoor and outdoor units must be setup by Samsung installer in order that Intesis communicates properly. Manual addressing is setup by means of DIP switches in outdoor unit and using the remote controller or DIP switches in the indoor unit.
  • Samsung NASA indoor units need to be configured to accept ‘central control’. To do so, they need to be configured with so-called ‘installation option code’ in which segment 5 of this code needs to be set to value ‘1’ to allow central control. Connect the Samsung NASA bus to connectors A3 (R1/+), A4 (R2/-) of gateway’s PortA. Respect the polarity

For more information about how to do this, contact Samsung:

• Samsung Small Business Academy [SBA]:
• This link will take the person to SBA, once they login, or create an account they will be taken directly to the training. Just let them know if they don’t have an account it can take anywhere between 4 -24 hour to get access, depending on how many accounts we are trying to vet and approve that day.
