Functional Specifications

 ASCII Communication ports 1 & 2 (PRT1. PRT2)

 Both ports are capable of transmitting and/or receiving ASCII character strings.

Each port is individually configurable:

o Termination types

o Stream mode

o Termination character(s)

o Message timeout

o Intercharacter timeout

o Packet size limit

o Baud rate: 110 to 115.2K baud

o Parity: none, even, odd

o Stop bits: 1 or 2

o Data bits: 5 to 8

o RTS on/off timing: 0 to 65535 milliseconds

o Minimum response delay: 0 to 65535 milliseconds

 Handshaking (optional)

o Hardware: RTS/CTS, DTR/DSR

o Software: XON/XOFF

 ASCII character strings up to 4096 characters in length supported

 Full hardware handshaking control provides radio, modem and multi-drop support

 User-definable module memory usage, supporting the storage and transfer of 

up to 4000 registers to/from the control processor

 Module error and status conditions returned to processor for diagnostic purposes

o Module status

o Port error status word (bitmapped)

o Port receive state

o Port receive character count

o Port receive block count

o Port transmit state

o Port transmit character count

o Port transmit block count

 All data related to the module is contained in a single controller tag with defined

objects to simplify monitoring and interfacing with the module

 Module communication data is transferred to the module via a predefined user

data type in the processor
