The opons can be edited to suit your applicaon:
• Enable RS-232 port: When it is unchecked, it powers down. When this
opon is checked, it powers up the RS-232 hardware. It then displays
the assigned COM port number.
Note: If you do not have a device plugged into the RS-232 port, the
port pins corrode more quickly when le powered up. Use the seng
to power down when it is not going to be used.
Note: Power consumpon during sleep is higher when the RS-232
hardware is powered up.
• Congure RS-232 Signals: Select Always enabled to have the RS-232
output signals driving and input signals enabled when the RT4 is
running or in sleep mode. Select Disabled during sleep to have the
RS-232 output and input signals disabled automacally when the
tablet is in sleep mode. If your app and/or RS-232 device experiences
communicaon failures when tablet enters or exits sleep mode, then
do not use this opon.
