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:
Precautions for Safe Use
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.
