Overview

The W&T RS232 Multi Computer Adapter 85603 permits 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.
Important: When powering the RS232 Multi Computer Ad-
apter externally 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.
