After the USB, Firewire, monitor output and audio inputs and outputs only the ExpressCard slots and the RJ-45 network card connector are missing.
Network cards are no longer used as much due to the mobility and convenience offered by wireless connections, while the ExpressCard slot despite its wide range of possibilities has not prospered due to the lack of support from manufacturers as well as the increased convenience of other USB-connected devices.
Likewise, if our team has these connections it is good to know the options it offers in case we can get more out of it.
RJ-45 is the name of the connector used for network cards. Despite the popularity of wireless networks that relegate it to the background, all Apple computers incorporate network cards (with the exception of MacBook Air) that can be up to Gigabit 101001000 Base-T.
There is little to say about a connection that most of us know. Anyway, despite the convenience of wifi connectivity, you can always use a wired connection due to the improvement in speed and especially to avoid possible interference.
In professional environments, to share multimedia material or carry out processes together it is essential to make use of this connection.
ExpressCard is a standard that replaces the old PCMCIA . These cards allow, depending on the choice of the developer, the use of PCI-Express or USB 2.0 connectivity. The peripherals that make use of ExpressCard are varied, from Wifi adapters, Bluetooth, Sound Cards, TV tuners, SD card reader, USB or Firewire port extension,…
Apple first included the ExpressCard34 slot in the MacBook Pro that was released in January 2006 . Since then, until the release of the new MacBook Pro range, it has not been a very popular connection. Only users with very specific needs have taken advantage of it by using cards to connect audio or video capture interfaces such as those from Matrox.
For the rest of the users they have gone a bit unnoticed and even the only way to get something out of it has been to look for an ExpressCard that is an SD card reader. That’s why Apple itself has replaced it with an SD reader in the current range, except for the 17″.
As data to be considered, the ExpressCard supports two card formats: ExpressCard34 (34 mm wide) and ExpressCard54 (54 mm wide L-shaped). The connector is the same, 34mm wide and 26 pins. But beware, Macs use the ExpressCard 34.
Interesting accessories if you have a Mac with an ExpressCard slot are solid-state memory cards like those from Transcend or Verbatin. These can be found in different capacities and can be used to host an alternative OS, etc…
It is not a connection but it is clear that some absent-minded users still do not know what they are for. Kesington locks allow us to secure our equipment : desktops, laptops, or monitors when we go to a public place.
