Description
VBUS – USB Power provided from upstream USB Host or Hub
D – = USB data signal, negative polarity
D+ = USB data signal, positive polarity
GND = USB signal ground
Drain = typically connected to the host PC case
Table 3.1 – USB "B" Receptacle Pin-Out
3.1.2 RS232
The RS232 port is configured as Data Terminal Equipment (DTE), with a 9-contact D-Sub Pin connector.
Pin assignments are according to TIA/EIA-574 which formally defines the assignments for a COM port
found on many personal computers. In addition, Ring Indicator (RI) may be re-assigned to provide
+5VDC to an external device with a maximum current draw of 250mA once the USB-COM232-Plus1 has
been enumerated by the system.
