IntelliTouch 2500S Serial Controller
Electrical
Supply Voltage and
Current
+5 Vdc, nominal (+4.75 to +5.25 Vdc).
60 mA, typical at +5 Vdc. Average power dissipation is 0.3 W, typical.
Supply must be capable of sourcing 100 mA, minimum.
Total noise and ripple requirement must be less than 100 mV (p-p) for
frequencies below 1 MHz, and less than 50 mV (p-p) for frequencies above 1
MHz.
Interface EIA 232E (Serial RS-232), DCE configuration. 8 Data Bits, 1 Stop Bit, No
Parity, Full Duplex.
Hardware handshaking: RTS/CTS
DSR is pulled HIGH (>+3V) by the 2500S when connected and powered. DTR
is ignored
Baud Rate 9600 (default) and 19200
Operating Modes Full IntelliTouch SmartSet or E281A-4002 protocols, jumper selectable.
Initial/ Stream/ Untouch/ Z-axis Enable Modes.
Touch Resolution 4096x4096, size independent, 255 levels of Z (pressure).
Conversion Time Approximately 10.4 ms per coordinate report.
Reliability MTBF greater than 300,000 hours per MIL-HDBK-217-F2 (using the parts
stress calculation method for ground benign environment with an ambient
temperature of 25
°
C).
