3. Attach the other end of the RS-232C cable to the host’s communications port.
4. Connect the tablet’s power cable to the tablet and to a wall power outlet.
5. Turn the 2500 tablet ON. The power switch is next to the power cord at the rear of
the tablet. 0 is off and 1 is on. The tablet will run a series of self-tests and then
beep to indicate it is ready.
Optional Power Input
Power can be applied to the tablet either through a line cord from an AC outlet or
directly from the host via the RS-232C connector if the host can supply +12 to +15 VDC
at 300 mA on pin 24 and power ground on pin 25. Remove the bottom cover and
connect the two pins labeled W3 on the printed circuit board if you wish to use this
option. When the host power option is used, the tablet will be turned on or off by the
host power switch, not the tablet switch.
