NOTES:
• The RS-232 Tx and Rx line pair must cross once between this connector and the destination.
• The length and preparation of exposed wires is important. The ideal length is 3/16 inch (5 mm).
• If the stripped section of wire is longer than 3/16 inch, the exposed wires may touch, causing a short
circuit.
• If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled out even if tightly
fastened by the captive screws.
• Do not tin the wires before installing them in the connector. Tinned wires are not as secure in the
connector and could be pulled out.
Digital I/O Connector wiring
Figure 6 shows two examples of how to wire the Digital I/O connector to:
• Monitor events such as a switch or sensor (example1)
• Power LEDs or other devices that accept a TTL signal functions (example 2)
