2. Place two fingers on both lock eject levers located on either side of the modem serial port
connector and press outwards in order to release the connector from the header on the CPU
board.
3. On the right hand side of the modem you will see the following three cables, in the following
front to back sequence:
•
Phone
•
Line
•
two-wire modem power
4. Detach the Phone cable plug from the jack on the modem in the same manner you would
detach a standard RJ-11 telephone plug.
5. Detach the Line cable plug from the jack on the modem in the same manner you would
detach a standard RJ-11 telephone plug.
6. Detach the two-wire modem power cable connector from the modem by pulling the connector
outwards from the modem.
7. Firmly grip the modem and pull out of the AccuVote-OS. Alternatively, you may use a flat
blade (—) screwdriver to pry the modem away from the chassis. The modem is attached to
the bottom of the chassis using double-sided adhesive tape, which should be carefully peeled
off from the bottom of the modem and the chassis. Clean any remaining material from the
adhesive tape using isopropyl alcohol.
8. Disconnect the modem serial interface connector from the modem.
9. Power the modem off.
10. If the AccuVote-OS is to be powered up without the modem ensure that the two-wire modem
power cable connector barrel is not touching any conductive surfaces, including the inside
surface of the chassis as it is covered with a conductive coating. We recommend removing
the two-wire modem power cable connector from the CPU board. Note the orientation of the
connector before removal.
10.22. Installing the modem
An AccuVote-OS may be installed with a modem used to program memory cards and transmit
election results. The modem is used to communicate memory card information and election
results at 2400 baud over telephone lines.
Before attempting this procedure, ensure that all external cables have been disconnected and the
unit is powered off.
1. Before installing the modem in the AccuVote-OS chassis, you must ensure that no residual
adhesive tape remains on either the bottom of the modem or the AccuVote-OS chassis.
Clean any remaining material from the adhesive tape using isopropyl alcohol.
2. Connect the modem serial interface connector to the modem before installing the modem.
3. A replacement modem comes with the two-sided adhesive mounting tape already on the
bottom of the modem. Note that this tape may be easily repositioned within 24 hours of
application. Firmly press the modem into the space provided for the modem in the AccuVote-
OS chassis.
When mounting the modem into the chassis, position it so that the body of the modem is up
against the power supply housing and the front of the modem — as opposed to the modem serial
interface connector — is flush with the front of the of the power supply housing. The main serial
port ribbon cable should travel partially under the power supply side of the modem but not
interfere with the two-sided mounting tape on the modem.
