Overview
T h e W & T M u l t i C o m p u t e r A d a p t e r p e r m i t s a
bi-directional connection of two serial data sources to a
peripheral device. Automatic switching between the two
senders is done on a time-controlled basis: The data sender
that wants first to output something automatically blocks the
outputs from the other source. If the data sender implements a
pause, both inputs are again ready to receive after a
configurable timeout time. Two LEDs on the front panel of the

Supply voltage
The supply voltage for the RS232 Multi Computer Adapter is
provided by an integrated switched-mode power supply. This
features a variable input voltage range and allows the T-switch
to be powered using the AC adapter provided or alternately by
any AC or DC voltage between 12 and 24V. The supply connec-
tion is reverse polarity protected and is made using the
included plug-in screw terminal.
When powering the Multi Computer Adapter

ternally you must ensure that the supply voltage used
is potential-free. Voltage sources with a ground reference
can damage the device and/or the connected serial devices.
We therefore recommend using the power supply included
in the scope of delivery.
