Product information

Description

The InLine 76660W internal serial adapter converts an M.2 module connection into four independent serial DB9 (9-pin) ports. It uses a PCIe 3.0 x4 interface with an ASIX AX99100 controller and supports data transfer rates up to 4 Gbit/s. The M.2 card receives power from the PCIe bus (3.3 V) and includes low- and high-profile slot brackets plus DB9 cables for installation in standard and compact systems.

Advantages

The adapter provides four serial 9-pin interfaces from a single M.2 module slot, with automatic PCIe lane detection at boot for straightforward integration. Onboard LED indication shows read/write activity, and no additional driver installation is required for supported operating systems. Compact M.2 dimensions and included mounting brackets make the card suitable for diverse chassis types.

Suitable for

  • Adding multiple RS-232/serial ports to desktop or embedded systems
  • Industrial controllers and legacy device connectivity
  • Systems with available M.2 (Key M) module slot and PCIe x4/x8/x16 slots

How to use

Install an appropriate M.2 module (Key M, sizes 2230–2280) into the adapter’s M.2 slot. Insert the adapter into a free PCIe x4/x8/x16 slot on the motherboard; the card will receive power from the PCIe bus. Connect serial devices to the four DB9 ports using the supplied cables. The card performs automatic lane detection during boot. Ensure the chosen M.2 module is compatible with your system and securely fasten the adapter using the supplied brackets and screws.

Usage recommendations

For stable operation, use a PCIe slot that supports PCIe 3.0 and verify operating system compatibility before connecting critical devices. Select the correct M.2 module size for the onboard slot and secure the card with the appropriate profile bracket when installing in compact systems.
