19.4 190-USB Operation
Page 178
A connection to the 190-USB option card can be used to send
commands to the 190 indicator. A description of the available
commands are describe in section 9.11 ASCII Commands.
NOTE: When the 190 indicator is turned OFF, power is
removed to the USB transceiver. The serial
communication software (e.g. HyperTerminal)
connecting the computer to the 190-USB must be
disconnected before the 190 indicator is turned OFF. If
the communication software does not release the
connection to the USB Comm port before power to the
190 indicator is turned off, the USB Comm connection
will not restore the connection when the 190 indicator
is powered ON again. To restore the connection, the
USB cable must be unplugged and reconnected.
