Globalink 3420


Globalink 3420 is an analog modem designed for data transmission over either leased or dialup lines, operating in both synchronous and asynchronous modes.

LEDS and double function keys in the frontal panel allow to configure, to dial up, to check both connection speed and whether the protocols for errors correction and data compression are on, as well as to activate links, among other functions.

Its software with flexible architecture allows firmware updating without changes in hardware or need for technical assistance.
