Slotbleck 2 x COM-port DeLOCK 41791

This Delock slot bracket installs into a free PC expansion slot and provides two external COM ports by connecting to an internal comport pin header with 2.0 mm pitch. It is designed for motherboards (for example some MSI and VIA models) that use a 2.0 mm internal serial header; it is not compatible with the more common 2.54 mm standard pin header.

Advantages

The bracket offers two DB-9 connectors for connecting external serial devices and a silver finish that integrates with most PC cases. It converts an internal 2.0 mm pitch serial header to two external COM ports, expanding legacy connectivity without modifying the motherboard.

Suitable for

• Connecting serial devices such as modems, industrial controllers or POS terminals
• Systems with an available expansion slot and an internal 2.0 mm COM header
• Legacy equipment integration in desktop PCs

How to use

Power off the PC and unplug it from the mains. Remove the case cover and insert the slot bracket into an empty rear expansion slot. Connect the bracket's cable to the motherboard's internal comport pin header with 2.0 mm pitch, ensuring correct orientation of pins. Replace the case cover, reconnect power and start the system. The connected DB-9 ports are then available for serial devices; install drivers for attached hardware if required.

Recommendations

Verify the motherboard manual to confirm the presence and pin pitch (2.0 mm) of the internal COM header before purchase. Do not force connection to a 2.54 mm header; incompatible pitch may damage pins. Use while the PC is powered off to avoid electrical damage.
