QUESTION:
Does anyone have the pinouts for the serial port of a Sparc20?
I am specifically looking for the pinouts for the B port of
an A/B duplex connection on the Sparc20. The A/B ports are on
a single connector and we need to split the B port off using a
Y connector.
ANSWER:
Host Circuit Board Port A Port B
PIN SIGNAL PORT SIGNAL SIGNAL
2 TD A TD TD
3 RD A RD RD
4 RTS A RTS RTS
5 CTS A CTS CTS
6 DSR A DSR -
7 GND A GND GND
8 DCD A DCD DCD
11 DTR B
12 DCD B
13 CTS B
14 TD B
15 TC A TC TC
16 RD B
17 RC A RC -
18 TC B
19 RTS B
20 DTR A DTR DTR
24 TCO A RCO TCO
25 TCO B
So, for example, port A pin 4 is RTS and connects to host pin 4;
port B pin 4 is RTS and connects to host pin 19.
