  • Supports both RS-422 and RS-485 protocols for flexible serial communication
  • New internal power cable ensures reliable signal integrity across all four ports

DB44 to four DB9 RS-422/485 cable

This internal cable splits a single DB44 connector into four DB9 ports for RS-422 and RS-485 serial communication. It connects a compatible PCI card to up to four serial expansion cards or devices. The assembly is supplied new and ready for installation inside a chassis.

Practical limits of the DB44 interface

The DB44 connector carries all signals for the four ports, so cable length and signal integrity depend on the host card specification. RS-422 and RS-485 buses have defined maximum distances and node counts that the host controller enforces. This cable does not add termination or isolation beyond the physical wiring. Builders needing more than four ports or a different connector type cannot use this assembly.

Questions about this item

Should I choose this DB44 to 4x DB9 cable for a single-port or multi-port RS-422/485 PCI card?

This cable splits one DB44 connection into four DB9 ports, so it matches a PCI card that presents four RS-422/485 channels on a single DB44 header.

What does the 4-port DB9 breakout actually give me inside the case?

It converts the card's DB44 interface into four separate DB9 connectors, each carrying an independent RS-422/485 serial link for four devices.
