Min. 16 ft (5 m)

Device pairing

Activation / Deactivation with service button

Automatic switch off after 10 minutes if no WLAN-client is connected.

Optionally, for cybersecurity reasons, the WLAN port can be permanently disabled in DT+ configuration.

Default SSID and WLAN password:
SSID = <ASN>_<Running number after the series letter> and password = <S/N>

Scan the QR code.
Example:
WIFI:S:PXC7.E400_0000550;T:WPA;P:1400052738;;
Then SSID = PXC7.E400_0000550 and password = 1400052738

NOTE: To determine SSID and WLAN password manually: Use the information from the Date/Series/SN block.
Example:
Date/Series: YYYYMMDDS0000001
S/N: 140000A12F Hex
