Figure 9. Wiring the RS-232 and IR Connector
Cross the Tx and Rx lines once between the source and target.
ATTENTION: The length of exposed wires is critical. The ideal length is
3/16 inch (5 mm).
• Longer bare wires can short together
• Shorter wires are not as secure in the connectors and could be pulled out.
