receive, and ground wires of the RS‑232 cable to the
provided 3‑pole captive screw plug, as shown in the
illustration at right. Connect the plug to the rear panel
RS‑232 connector (see figures 1 and 2,
previous page), and the other end of the cable to your
computer serial port. Protocol for the RS‑232 port is
9600 baud, 8 data bits, 1 stop bit, no parity.
Config port — Connect a USB mini‑B cable to the front panel USB connector (see figures 4 and
•
5, , on the next page) for USB control.
