When shopping computers peripherals, the key decision is whether you need direct HDMI links, USB peripherals placed far from a host computer, or vintage computer hardware for a project. These listings span USD 48.44 to USD 300, but they are not interchangeable: two entries are matching AddOn cable packs, while the Extron and National items address much more specialized jobs.
Quick take
- Pick either matching AddOn HDMIHSMM10-5PK Video Cable entry for a set of direct HDMI connections between compatible display and media devices.
- Choose the Extron USB Extender Plus T when the goal is extending USB peripheral signals through a network or CATx run rather than carrying video.
- Consider the National MSX CF-2000 only as a vintage hardware project, since its condition is stated as for parts or not working.
- The two AddOn entries share the same title, MPN, UPC, condition, and listed price, so they represent the same cable configuration rather than two distinct types of peripheral.
Listed-price comparison
| Listed item | Listed price | Price marker | Main role |
|---|---|---|---|
| AddOn HDMIHSMM10-5PK Video Cable - matching entry 1 | USD 48.44 | Direct HDMI A/V connections | |
| AddOn HDMIHSMM10-5PK Video Cable - matching entry 2 | USD 48.44 | Direct HDMI A/V connections | |
| Extron USB Extender Plus T Transmitter 60-1471-12 | USD 300.00 | Extended USB peripheral signals | |
| National MSX CF-2000 Personal Computer + Joystick + RAM Cartridge | USD 208.00 | Parts or restoration-oriented MSX hardware |
Decision matrix
Start with the connection you actually need. For HDMI-enabled devices such as an HDTV and a Blu-Ray or DVD player, the AddOn pack is the direct match. Its cable description identifies HDMI male-to-male connections, whereas the Extron is designed around USB peripheral signals and a host computer.
The Extron is the focused pick for USB 2.0 devices where distance is central to the setup. Its stated network reach is up to 1,980 feet, with a point-to-point CATx specification of up to 330 feet. The National is a different purchase altogether: it is a National MSX CF-2000 personal computer package from Japan, not a cable or USB-extension component.
Product notes
AddOn HDMIHSMM10-5PK Video Cable - matching entry 1
Choose this AddOn HDMIHSMM10-5PK entry when the project is to make several direct HDMI connections. It is described as a five-pack of 10-foot/3 m high-speed HDMI cables with Ethernet and HDMI male connectors at both ends, intended for links such as HDTVs and Blu-Ray or DVD players. The description also states support for full 1080p with a 120 Hz refresh rate. Its limitation is equally clear: this is an A/V cable pack, not the Extron USB transmitter and not a standalone computer. It suits repeated HDMI runs rather than an extended USB arrangement.
AddOn HDMIHSMM10-5PK Video Cable - matching entry 2
This second AddOn HDMIHSMM10-5PK entry carries the same product title, MPN HDMIHSMM10-5PK, and UPC 821455059197 as the other AddOn entry. Choose it when matching identifiers matter to a cable plan: it is the same new A/V cable item, specified as a five-pack. The limitation is that this matching entry does not create a different device category or connection purpose. It remains the listed HDMI male-to-male arrangement, making it appropriate for direct HDMI cabling instead of USB signal extension or a vintage-system project.
Extron USB Extender Plus T Extender for USB Peripherals Transmitter 60-1471-12
The Extron USB Extender Plus T is the right direction for a setup that needs USB peripherals connected back to a host computer across substantial distance. The series description covers USB 2.0 through 1.0 devices at data rates up to 480 Mbps and notes compatibility with USB 3.0 devices operating at USB 2.0 data rates. It also describes USB peripheral emulation for host-computer booting. A key limitation is in the title: this listed unit is the transmitter. The active four-port hub is described as a receiver feature, rather than the transmitter's stated role.
Junk National MSX CF-2000 Personal Computer + Joystick + RAM Cartridge Japan
The National MSX CF-2000 fits a shopper seeking an older MSX computer project rather than a ready-made modern peripheral connection. Its title includes a joystick and RAM cartridge, and the description identifies the machine as a National MSX item from the 1980s with Japan as its country of origin. The important limitation is explicit: its condition is for parts or not working. The description also states that an AV cable is not included. Choose this one for the particular CF-2000 hardware package and project-oriented condition, not as a straightforward substitute for an HDMI cable set or USB extender.
Final recommendation by use case
For display-device connections, either matching AddOn HDMIHSMM10-5PK entry is the practical choice because it is built around a multi-cable HDMI setup. For USB peripherals that must operate at the stated network or CATx distances from a host computer, the Extron USB Extender Plus T is the purpose-specific selection. Select the National MSX CF-2000 only when the appeal is the named MSX system package and a parts-or-repair project.
