vrf USB and VEE and max distances

Question asked by VRFuser on Aug 4, 2008
Why don’t you just use a media converter.

 

Convert from USB to fiber. I think the max length is then something like 2Km. then convert back

Hello,

Last week we have set up such a connection.
It consists of an Agilent E5813A Networked 5-port USB Hub, an USB extender of 2m, and then an Agilent 5805A 4 port USB-RS232 serial converter.
(Windows XP, IOexpert 15, HPVEE 8.5).

It works fine.

Greetings,

Achim Van Theemsche.

Hi,


If I remember correctly, combination of Agilent's E5813A
Networked 5-port USB Hub and FTDI's US232B USB-Serial converter
worked well.
