RS232 Multi Computer Adapter, Model 85603
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 switch indicate which of the two input channels is
currently active.
Supply voltage
The supply voltage for the T-switch 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 T-switch externally you
must ensure that the supply voltage used is potential-
free. Voltage sources with a ground reference can
damage the T-switch and/or the connected serial devices.
We therefore recommend using the power supply
included in the scope of delivery.
