106100 Processor Board
The following table contains information about general features and specifications of
the 106100 processor board.
Processor 80C31 CMOS Microprocessor
Memory The EPROM has 64K bytes (program storage).
The RAM has 1024K bytes of battery-backed data storage.
Programming
Language
BASIC
Program Loading The program is loaded via a modem over standard, voice-grade telephone lines or via a
direct serial connection.
Communication The processor board uses a logic-level serial bus for communication with sensor
interface boards.
The modem communicates with the central computer via a 1200/2400 baud rate, Bell
224, Bell 212A, V22, V22.bis compatible modem/modem interface over standard, voice-
grade telephone lines.
Direct communication is available using a portable computer and an IS cable (ADS part
number 106228A).
Protocol The proprietary YAPP query-response protocol with CRC-16 error detection is used for
modem communications.
Discrete Input The discrete input is a 16-bit counter for counting external contact closures.
Discrete Output The discrete output is an optically-isolated, open collector programmable output.
Temperature
Measurement
Analog inputs are read from on-board (standard) and off-board (optional) temperature
sensors.
Memory Capacity The board can hold 174752 readings (1024K memory).
Memory Backup
Battery
The 3 V lithium battery protects against loss of monitor memory.
Clock This crystal-controlled, hardware clock/calendar is lithium battery backed.
Switches 8-position identification switch
An 8-position option switch allows selection of the operating parameters, e.g. mode of
communications or baud rate.
LED LED is ON when processor is engaged in external communications, such as modem
communications.
