Operating Modes
Run Mode: Digitizer outputs coordinate data continuously.
Increment Mode Filter: Puts a movement filter on data in any mode. The transducer must
move N counts before the data can be sent. Then both axis data are updated. If out of
proximity data is enabled in increment mode, one data point may be sent on leaving
proximity.
Prompt Mode Modifier: Places the additional restriction on data transmission that the host
must transmit a prompt character to the tablet for each data point output. All other rules
of normal operation apply. The prompt character is “?”. Prompting is a feature, which
operates in conjunction with any of the above standard modes.
Send Data Out of Proximity Mode Modifier: If this flag is set, coordinate data will be sent
when it meets the output conditions in or out of the active area. Cordless units may not
respond to button information until cursor is close to tablet.
NOTE: This command should be sent after the mode commands.
Send Data in Margin: If this flag is set, coordinate data point will be sent when it meets the
output conditions in the active area or when in margins.
NOTE: Margins on some of the tablets are very small and are larger leaving the tablet than
coming in.

Plug and Play (WINDOWS 95)
*.2+/- .035 SEC
DTR goes high and then within 165 msec to 235 msec CTS goes high. Then the tablet sends
the “plug and play” string at 1200 baud 7 data no parity 2 stop bits. The string could be
“(^a$CAL0010\\TABLET\\ 4x5 TABLET cs) cr If” or similar. See plug and play spec for more
information.
DTR Wiggle
RTS should be high well before DTR is dropped (1/18). DTR low times should be at least
one timer tick (1/18) long and no longer than two ticks. This wiggle does not work 100%
compared to older products. It is the same as sending “ESC % C 1 N 8 1 cr” and “ESC % A 0
cr.” Go to effect at *2. CTS should be low for at least one timer tick and DTR should be
high during this time. At time *3, the tablet will send “T” and for each time CTS is toggled,
one more “T” will be sent. To get out of this mode, send the tablet “ESC % VR cr for a hard
reset or use the “ESC % A1” command.

Commands (RS-232)
DC1 (X ON) start transmission after a x off (SAME AS ESC % A 1).
DC3 (X OFF) stop transmission on the next packet (SAME AS ESC % A 0). “?” is the prompt
character.
