Bottom line: The StarTech.com 2m Black Straight Through DB9 RS232 Serial Cable ($7.95 on Amazon as of 2026-10-21 16:22 UTC): Straight-through DB9 pinout, no crossover surprises on standard RS232 gear; main trade-off: straight-through only, will not work where a null-modem crossover is required.

Pros & Cons

Pros

  • ✓ Straight-through DB9 pinout, no crossover surprises on standard RS232 gear
  • ✓ 6.6 ft / 2m adds real desk-to-rack reach without floor slack
  • ✓ Male-to-female ends extend an existing run instead of replacing it

Cons

  • ✗ Straight-through only, will not work where a null-modem crossover is required
  • ✗ 2m fixed length, no shorter or longer option in this part number
  • ✗ DB-9 only, no DB-25 or USB-to-serial conversion included
  • ✗ Black jacket makes it hard to spot in a dense cable bundle

Manufacturer description

The StarTech.com MXT1002MBK is a 2m (6.6 ft) straight-through DB9 RS232 serial extension cable that adds reach between a male DB-9 port and a female DB-9 connection. If you are wiring up a serial console, a retro PC, a POS terminal, a UPS management port, or a bench instrument, this is the plain, straight-through pinout you want: DB-9 male on one end, DB-9 female on the other, no crossover, no adapters to source separately. The 6.6 ft length is the sweet spot for pulling a serial device out from behind a desk or rack without dangling slack across the floor. The all-black jacket keeps it…

SpecPicks Verdict

SpecPicks scored StarTech.com 2m Black Straight Through DB9 RS232 Serial Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the keyboards & mice category. StarTech.com's keyboards & mice lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for keyboards & mice of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Is this a null modem cable or a straight-through cable?

It is straight through. The DB-9 pins map one to one, male to female, so it extends an existing RS232 run rather than swapping TX and RX. If your setup needs a null-modem crossover, this is the wrong cable.

How long is the StarTech.com MXT1002MBK?

6.6 feet, or 2 meters. That is the only length for this part number; StarTech.com sells other lengths under different SKUs.

What connectors are on each end?

DB-9 male on one end and DB-9 female on the other, which is the standard configuration for extending a serial port out to a device.

Will this work with a USB port on a modern PC?

No. Both ends are DB-9 RS232, so you need an actual serial port on the host or a separate USB-to-serial adapter. This cable does not convert signals.
