Carlson RT4 User Manual
Congure pin 9 as input or power supply: Pin 9 is the Ring-In signal
input. It is rarely used by devices anymore and has become a popular
pin to provide a power source to an RS-232 device.
Select Input if your device uses Ring-In signal or if it does not need to
be powered from the RS-232 port.
Select Power supply enabled to make pin 9 a power supply to be used
by the RS-232 device. The power supply is enabled automacally
without needing any interacon with the COM port. Depending on the
model, the power supply supplies either 5 VDC or 12 VDC.
Select DTR enables power supply to make pin 9 a power supply (5 VDC
or 12 VDC depending on model). The power supply remains o unl
the user applicaon opens the COM port and asserts the DTR signal.
When the DTR signal de-asserts, the power supply turns o again.
Check Disable power supply during sleep to cause the power supply to
automacally turn o when the tablet is in sleep mode. This can allow
the RS-232 device to conserve baery power in sleep mode. If your
app and/or RS-232 device experiences communicaon failures when
the RT4 enters or exits sleep mode, then leave this opon unchecked.
