GND and SGND areinternally connected through filtering circuitry which can be permanently damaged if subjected to voltagedrops over 0.8 V dc.Note: To avoid electromagnetic interference when the reader is connected to a TCNM-ACBB1 connectionbox, verify the jumper positions in the TCNM-ACBB1 as indicated in p/n 174477TCNM-ACBB1Installation Manual, available atwww.bannerengineering.com.3.7.1 Power SupplyPower can be supplied to the reader through the TCNM-ACBB1 spring clamp terminal pins.The power must be between 10 V dc and 30 V dc only.It is recommended to connect the device CHASSIS to earth ground (Earth) by setting the appropriate jumper in the TCNM-ACBB1 connection box. See p/n 174477TCNM-ACBB1 Installation Manual, available atwww.bannerengineering.com, fordetails.3.7.2 Main Serial InterfaceThe signals relative to the following serial interface types are available on the TCNM-ACBB1 spring clamp terminal blocks.The main serial interface type and its parameters (baud rate, data bits, etc.) can be defined by the user via BarcodeManager. For more details refer to the Help On Line page of the Reading Phase step (Channels) in Barcode Manager.Details regarding the connections and use of the interfaces are given in the following sections.11 Do not leave floating.
