Electrical Connections and Setup
The following figure shows a typical layout.
The dotted line in the figure refers to an optional (temporary) hardware configuration in which a
portable PC can be quickly connected to the TCNM-ACBB1 (and consequently to the reading device
auxiliary interface) through the internal 9-pin connector. This allows monitoring of the data transmitted
by the reading device or configuration through the utility program (see the reading device Installation
Manual for more details). The reading device auxiliary interface signals are also available on the internal
spring clamp connectors.
After making system cabling and switch settings, connect the reading device to the 25-pin connector on
the TCNM-ACBB1 housing.
Switch ON the TCNM-ACBB1 power switch. The Power LED turns on (blue) when the power connection
has the correct polarity. The Power LED turns on (red) in case of wrong polarity.
After system functioning has been verified, close the TCNM-ACBB1 using the two cover screws.
Power Supply
Power is supplied to the TCNM-ACBB1 through the Vdc and GND pins provided on the spring clamp
connector.
The power switch switches the power supply ON or OFF for both the TCNM-ACBB1 and the connected
reading device.
The power switch does not control power to the Vdc/GND, +V/-V spring
clamps, therefore any devices connected to these signals (i.e. external
trigger, encoder, etc.), are live and are not protected from polarity
inversion. Disconnect the power supply when working inside the TCNM-
ACBB1.
