Xplor RESIDENT SOFTWARE The universal language of BASIC is built into every Xplor PDC, making it easy to program with a computer or terminal. The BASIC interpreter and utilities use only 4K bytes of space in the CPU ROM. Key features include: Interactive program editing at 300 to 57,600 baud Autoexecution of user's BASIC program on power up Signed 16-bit integer arithmetic with hexadecimal option 26 integer variables named A-Z Functions: ABS(x) and RND(x) Logical operators: NOT, AND, OR, XOR Special operators: DBY, XBY, IBY, BIT Arithmetic operators: (+), (-), (*), (/), MOD Compare operators: (>), (<), (=), (< >), (> =), (< =) Direct commands: RUN, LIST, NEW Statements: CALL, END, FOR-TO-NEXT, GOSUB-RETURN, GOTO, IF-THEN, INPUT, ONTIME-IRET, PRINT, REM, SLEEP, LET (implied) UTILITIES Load Intel Hex files (8051 assembly language) Software real-time clock/calendar function FREQ - Measure frequency input (range = 0-65kHz) CHAN - Read on-board A/D converter (analog models only) LIBRARY ROUTINES Transmit X-10 compatible codes Interrupt driven serial buffer LCD and keypad drivers Print a character string stored in EEPROM Find the BASIC program length Print the current BASIC line number OPTIONAL Xplor CPU UPGRADE An 89C52 or equivalent CPU (8051 family) containing TB52 in ROM is standard on all Xplor Series PDCs. A CPU upgrade is available that adds more capabilities simply by replacing the 89C52 CPU with a more powerful "Fx" series (87C51FB) CPU on any of the Xplor PDCs. The CPU upgrade has added features but does not affect the basic functionality of the standard Xplor-52 series CPU. The "Fx" series CPUs have an enhanced serial port, an extra 16-bit timer/counter (PCA) with 5 compare/capture registers, and a watchdog timer.   BUYER PROTECTION All BlueEarth controller products and accessories are backed by a 90-day limited warranty as well as an accident protection policy.
