What Is The I/O Capacity Of A D20 System - GE D20 Technical Overview

D20/D200 Technical Overview

5.4 What is the I/O capacity of a D20 system?

The D20 can support up to:
− One redundant D.20 channel, supporting up to 120 I/O peripherals
− Seven RS-232 or RS-485 ports
− Two Ethernet ports
For example:
On each of its two D.20 ports, the D20 can support the following:
Example I/O Peripherals
A 120 - D20 S
B 120 - D20 A
C 100 - D20 A
20 - D20 S
5.5 What is the I/O capacity of a D200 system?
The D200 can support up to:
− Four D.20 ports (two per main processor), supporting up to 240 I/O peripherals
− 49 RS-232 or RS-485 ports (seven per main processor)
− Two Ethernet ports
For example:
On each of its four D.20 ports, the D200 can support the following:
Example
A
B
C
5.6 What are the added features of the ME II Main Processor
over the ME Main Processor?
Equipped with a D20ME II Main Processor, the D20/D200 can support RS-485 communications
on all seven communications ports. End devices can be supported at distances up to 4000 feet,
and the D20/200 can support up to 32 devices on each communication port, without the need for
external converters.
