Shield
Cable shield connected to chassis and 17-pin connector shell
Important: Do not connect GND and SGND to different (external) ground references. GND and SGND are
internally connected through filtering circuitry which can be permanently damaged if subjected to voltage
drops over 0.8 V dc.
3.8.1 Power Supply
Power 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 174477
details.
3.8.2 Main Serial Interface
The 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 Barcode
Manager. 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.
RS232 Interface
The RS232 interface is generally used for Point-to-Point connections. When it is connected to the host computer it allows
transmission of code data.
The following pins are used for RS232 interface connection:
