LEDs for indication on LD-63
• PWR: Indicates that the converter has power.
• TD: Indicates that the converter is receiving data on RS-232/V.24, RS-485 side.
• RD: Indicates that the converter is sending data on RS-232/V.24, RS-485 side.
• Rx1: Indicates received data on fiber channel 1.
• Rx2: Indicates received data on fiber channel 2.
• Tx1: Indicates that the converter is sending data on fiber channel 1 from RS-232/V.24, RS-485 side.
• Tx2: Indicates that the converter is sending data on fiber channel 2 from RS-232/V.24, RS-485 side.
