Psion Communication Solutions

With the plethora of hardware solutions, it's getting difficult to keep all this in our heads! So here's a visual reference as to what's required to connect your Psion (be it a 3a, 3c or 3mx, 5 or 5mx) to a modem or directly to the internet. Warning: a long page with many graphics! You might also use this to remind yourself what to pack for the next trip out of town...

Series 5mx, 5, 3mx, 3c Solutions

desktop modem

Cheap but bulky. Good for a user that is often at a desk, near a land-line. You may use any desktop modem.

portable modem

I now use a (discontinued?) portable battery-powered fax/modem (microcom TravelPorte) while away from home. It operates up to 14.4k bps for fax and modem communications; it supports cellular connections. Battery life is about 2 hours (pah!). It also comes with an AC adapter.

Psion Travel modem

Psion offers a 14.4 data/fax modem that plugs directly into the Psion. Nice. Very compact. Not cheap. Also requires a land-line. There exist some nice carrying cases that fit both the Psion and the Travel modem.

Series 3a Solutions

desktop modem with normal 3Link cable

Cheap but very bulky. Good for a user that is often at a desk, near a land-line. If you have a 512kb, you will also need a 512kb or higher SSD...

3Fax modem

Rather low-end these days but if you're just doing e-mail, still a viable solution. Nice leather cases were designed to hold both units. Maximum fax speed: 9600; data: 2400!

Series 5mx, 5, 3mx, 3c, or 3a Solutions

PCMCIA cellular modem

For the truly mobile user. The 5mx, 5, 3mx, and 3c use the same PC Card adapter while the one for the 3a is different. Assuming one is in range of a cellular station, the Psion can work anywhere. Expensive. Be sure to keep lots of fully-charged extra batteries on hand. Note: the battery charger you have to carry around negates many of the portability benefits...

P.S. your 3a must have at least 512kb memory.

land-line PC Card modem

If you already have a PC Card modem, this is the cheapest solution. The 5mx, 5, 3mx, and 3c use the same PC Card adapter. This is different from the 3a. An Xjack modem simplifies connections slightly.

infrared solutions new!

Nokia 8810 or Ericsson SH888 mobile phones have built-in infrared (IR) modems (see the Psion mobile communications site for more information). This is the most compact solution to date! Truly wireless!
