W&T
RS232 Universal Serial T-Switch

Display and control elements

The device uses four LEDs, a green „Power" for indicating
correct supply voltage and the LEDs marked „A" and „B" to
indicate which input channel is active.
The LED marked „Error" indicates the presence of parity or
framing errors in running data traffic and can only be
cleared explicitly by pressing the „Clear" key. The „Clear" key
resets the T-switch and deletes all internal data and error
memories.
Pressing the „Dump" key when the device is turned on
outputs the current setting of the T-switch on whichever
serial port has been selected using the DIL switches.
Additional information about this function can be found in
the section Diagnostic functions > Setting-dump.
