Oiltech Controls’s Insight
This card is a reliable bridge between PCs and ControlNet. The redundant BNC ports are valuable for critical networks – you can connect to both trunk and drop or use as backup. Always verify your PC has an available 5V/3.3V PCI slot. We recommend using the 1786-CP cable for stable programming connection.
FAQ – Expert Selection Guide
Q: What is the difference between RJ45 and BNC ports?
RJ45 connects a programming terminal (e.g., laptop). BNC connects to the ControlNet trunk or drop cable. Both are active simultaneously.
Q: Can I use this card in a PCI‑Express slot?
No. It requires standard PCI or PCI‑X. Adapters are not recommended.
Q: What cable do I need for programming?
Use 1786‑CP (RJ45 to RJ45) – standard Ethernet cable may not work reliably.
Q: Is the 1784-PCIC hot‑swappable?
No. You must power off the computer before inserting or removing the card.
Q: How do I verify the card is working?
Check RSLinx – the card appears as a ControlNet device. LED indicators on the bracket show link activity.
