1 NB Overview z Precaution for Cable Fabrication The COM 2 ports included in this manual and marked by cable manufacturers are intended for the PT of NB5Q/NB7W/NB10W-TW …… B models, therefore when communication connection is carried out with the COM 1 port of NB3Q-TW …… B, please refer to the pin definitions in this section prior to connection. z Serial Port COM2 • NB5Q/NB7W/NB10W-TW …… B Serial port COM2 is a 9-pin D-type socket port. This port supports RS-232C/RS-485/RS-422A communication function. The pins are defined as follows: z USB HOST NB …… -TW01B is equipped with USB HOST port, which is USB A-type port.
Through this port, USB memory can be connected to perform uploading, downloading, project operation and storage of related data. And its pins are defined as follows: 1 2 3 4 When connecting the equipment with the USB HOST connector, make sure the supply equipment’s current capacity is below 150mA before using it. The DC+5V voltage output of the NB Unit is +5V±5%, and the maximum current is 150mA.
