NOTES:
• The length of exposed wires is critical. The ideal length is 3/16 inches (5 mm).
• If the stripped section of wire is longer than 3/16 inches, the exposed wires
may touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16 inches, wires can be easily
pulled out even if tightly fastened by the captive screws.
This port is RS-232 only, with the following protocols:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
