BRUEL & KJAER 2236 User Manual

Sound Level Meters are often used for
monitoring in remote places, and you
may want to “monitor the monitor” or
transfer measured data to your home-
base PC, without going to the measure-
ment site. A telephone connection —
wired or wireless — is a convenient way
to transfer measurement data. And mo-
dems are a vital link in the chain of trans-
mission. This application note explains
what equipment you need and how to
use it.
Please note that only Brüel&Kjær Types
2236 and 2260 are supported for modem
connection. Types 2231, 2237 and 4436
need special handshaking modes, which
cannot be activated via modem.
