PIN .5 (PIN 4) - Clear to Send. This signal is sent by NICE to the terminal. A high
signal
(+.5V)
tells the terminal that NICE is ready to accept data.
Use of PIN .5
ensures that the terminal will not transmit at a rate faster than NICE can accept.
PIN 20 (PIN 6) -
Data
Terminal Ready. This signal is sent to NICE by the terminal.
A high signal tells NICE that the terminal is ready to accept data. Use of PIN 20
ensures that NICE will not transmit data faster than the terminal can accept it.
PIN 6 (PIN 20) -
Data
Set
Ready. This signal is sent by NICE to the terminal. A
high signal
(+,V)
tells the terminal that NICE has been installed and power has been
applied to the target system.
PIN 7 (PIN 7) - Ground, is the return path for the previous signals.
INSTALLATION
To install NICE:
1.
Remove the Z80 microprocessor from the target system.
2.
Connect NICE, using either the pin plug provided or the short 40 pin cable
connector.
o
Whenever possible, use the pin plug. The pin plug reduces signal noise. Use
the 40 pin cable only if you cannot physically attach NICE to the target
system.
o
Be sure that pin l of the target system is connected to pin l of NICE.
Otherwise, you may damage NICE's custom circuits.
3.
Attach the terminal to NICE using the communication cable provided.
