Connecting Control Cables
Many
are desigened for connecting test equipment via control cables. Typi-
cally, these connections are straight forward and require no precautions.
However,
take special care
in the following cases:
●
In I/O modules (input / output), avoid overloading the
digital input lines
. The maxi-
mum voltage to be applied directly to the input connectors is TTL level: standard
3.3
V
DC, tolerating up to 5
V
DC. For voltages >
5
V
DC up to 28
V
DC, insert a
resistor in series with a minimum resistance of
22
k
Ω
.
●
In the satellite system, use the
[Wired Link]
connectors
only
for connecting the
remote control module R&S
OSP-B200R with the satellite unit R&S
OSP-B200S2.
Connecting a [Wired Link] connector to any other device's connector can damage
your equipment.
