Sewell Part # SW-4721

"The entire process was perfect - good price, good quality, good service, quick delivery."


The Quatech rugged serial (RS-232) PCMCIA card gives your serial devices the power of mobility, allowing you to connect any serial device to your laptop's PCMCIA slot (aka PC Card Bus).

Rugged vs. Detachable

Computer manufacturers have begun eliminating serial ports from laptops and desktops, but there are still millions of serial devices out there. The Quatech Serial PCMCIA card allows the user to have a dedicated, independent serial port for their devices, and features a rugged attached cable. Many field workers that use serial adapters with their laptops lose or break the attachable cable. This card features a robust difficult-to-break attached cable that will never need replacing.

I have a Sony Vaio PCG-GRV550 laptop and am looking at purchasing a weathershack.com WS-2315 weather station. The weather station states that download of data is only with a true serial port not a USB add-on serial port. First question: Is your SW-4721 Serial PCMIA card compatable with my laptop? Second Question: Will this PCMIA serial port be a true r232 IOIO serial port [not a USB serial port] so I will be able to download data? If you are not sure I plan to call weathershack and ask them but is there any specific information I need to give them about the SW-4721 serial port that will tell them whether this PCMIA care will work or not? Thank you.


This should be compatible with your laptop. While they are more similar to integrated hardware than a USB virtual COM port, there are still some differences. I believe this uses the Texas Instruments TI 1420 chipset. You can contact weathershack to see if their system is compatible with that chipset.
