Installation
2.1 Example Applications and Configurations
2.1.1 Wiring
Insert the A-plug into an available USB Host or Hub port. Insert the B-plug into the B-receptacle on the
USB-COM232-Plus1.
RS232 cables have followed a standard 9-pin configuration on a D-sub connector since the mid 1980s.
The USB-COM232-Plus1 follows this standard as a Data Terminal Equipment (DTE) device. If the RS232
equipment being connected is a Data Communication Equipment (DCE) device, it’s typical that a straight -
through cable can be used.

Signal Name
DCD = Data Carrier Detect
RXD = Receive Data
TXD = Transmit Data
DTR = Data Terminal Ready

DSR = Data Set Ready
RTS = Request To Send
CTS = Clear To Send
RI – Ring Indicator / +5VDC

Table 2.1 – RS232 DTE to DCE connection with straight-through cable
If the USB-COM232-Plus1 is connected to another DTE device, a serial “null - modem” cable is required. A
null-modem handles connecting output signals to the corresponding input signals on the other end.
Table 2.3 shows a typical null-modem cable. Note that RI and DCD are not always used.

Some serial devices may require certain handshake signals be connected. Refer to your device manual
for cabling details.
