3.4.9.4 RS232, RS485 and USB Interfaces
The RS232 serial interface provides control of all functions available, with electrical isolation between the RS232 input
signals and the internal control electronics (isolated power shared with CC TRIG input and RS485). The hardware is
configured as RS232 Data Communications Equipment (DCE) standard with the pin configuration shown in Table 3.7.
The USB is an alternate for the RS232 interface. The USB connector is a type B connector. The USB connection is a
device connection. The connection between the USB and the PC is a virtual serial port. The driver for the USB is
included with the most recent versions of Windows.
The RS485 is similar to the RS232. The RS485 allows multi-drop configuration (RS232 is point-to-point), which
means multiple devices may be on the same wiring network. 5V power is provided on the connector (limited to
20mA). There is also a connection for the shield of the cable. The cable shield should only be connected at one end.

No hardware signals are currently used for handshaking. The DSR signal is available to provide limited power for
some RS232 translator devices (10mA max).
