2.1.15. Modems
The AccuVote-OS modem allows you to program memory cards and transmit election results to
the host computer using the GEMS feature.
The modem is connected to the CPU board with a serial interface. Power is supplied by means
of a connection to the CPU board, which is in turn connected to the power supply. The
Line
and
Phone
jacks at the rear of the AccuVote-OS are connected to the modem by means of RJ-11
cables.
Line
is used to connect the modem to a phone line — the
Phone
jack may be optionally
used to connect the modem to a telephone handset, although normally it should be loaded with a
dummy phone plug.
Each modem is pocket-sized, transmits data at a rate of 2400 baud and weighs approximately 4
oz. Modems are set by default to transmit an eight bit character, with no parity, and one stop bit.
