FAQ – 5A26141G06

1. What is the maximum RS-485 cable length?
   At 19.2 kbps, RS-485 supports up to 1200 m. This 4.5-foot cable is intended for intra-cabinet connections between controller and local I/O transition panel.
2. Can I use a standard DB9 serial cable instead?
   No. Standard DB9 cables may not have correct pinout or shielding for Ovation RS-485 bus. Use only Emerson-approved 5A26141G0x cables to ensure signal integrity.
3. What does the G06 revision indicate?
   G06 denotes a specific length (4.5 ft) and connector finish. Other revisions (G01–G05, G07+) may vary in length, shielding, or pinout.
4. Is this cable used for Profibus DP?
   No. This is for Ovation proprietary local I/O bus. Profibus DP uses different connectors (typically 9-pin D-Sub with specific Profibus pinout).

Installation Guide

• Step 1: Power down controller and I/O branch before installing cable.
• Step 2: Connect one DB9 end to controller I/O bus port; connect other end to local I/O transition panel (3A99266G01 or similar).
• Step 3: Secure cable with strain relief to prevent connector damage from vibration.
• Step 4: Verify continuity with multimeter: pins 3 (B+), 8 (A−), and 5 (GND) should match end-to-end.
• Step 5: Energize system and verify I/O communication: no red fault LEDs on I/O modules, all tags updating in controller.

Selection Tips

Order 5A26141G06 for 4.5-foot local I/O bus connections within Ovation controller cabinets. If your cabinet layout requires longer cables, check for 5A26141G0x variants or custom lengths. Always verify your controller and transition panel use DB9 connectors; newer systems may use RJ45 or terminal block connections instead.
