Reliability

+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.

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

9600 (default) and 19200

Full IntelliTouch SmartSet or E281A-4002 protocols, jumper selectable.

Initial/ Stream/ Untouch/ Z-axis Enable Modes.

4096x4096, size independent, 255 levels of Z (pressure).

Approximately 10.4 ms per coordinate report.

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).
