The terminal receives programs at 19,200
baud from an AST Premium 286 PC - the DNC system computer - in the company's engineering office.
A single CT image would cross over that 9,600
baud modem in 45.5 minutes.
The board is available at 508-794-0762 at both 1200 and 2400
baud. Once again the standard BBS settings should be used and ANSI graphics are available for users with this capability.
Operator controls include eight
baud rate selection switches (from 150 to 19.2K), CTS delay selection switches, a loop-back/normal switch, synchronous/asynchronous jumpers and internal/external clock jumpers.
For example, most computers must communicate with each other or with printers at the same
baud rate.
The system would only operate at 1200
baud. A
baud rate of 2400 was tried but was very undependable.
The optical interface transmits at a rate of up to 19,200
baud and the acoustic coupler at a rate of 1,200
baud.
* Programmable
baud rate and data formats with 128-byte transmit and 384-byte receive buffers.
The encoder/decoder offers a programmable
baud clock generator with 13
baud rates from 1,200 Hz to 115kHz.
The unit has two RS-232 serial ports, one male and one female, with programmable
baud rates from 300 bps to 115,200 bps.
