[comp.sys.hp] serial port on HP9000/360

brazile@iex.uucp (Robert Brazile) (12/13/89)

I would greatly appreciate it if someone could send me the pinouts of the
9 pin serial port on the back of the HP9000/360 or let me know which manual
describes it.

Thanks,

I may be speaking prematurely, but I seem to remember that this
is the same as the PC-AT serial connector.  Therefore, your local
PC dealer should have the info in any data sheet.

There's a chance that I remember this wrong, and I know there is
an HP manual that describes it, but this may be the quickest way 
to get the info you need.

	1 - DTR: data terminal ready
	2 - TXD: transmitted data
	3 - RXD: received data
	4 - RTS: request to send
	5 - CTS: clear to send
	6 - DSR: carrier detect
	7 - GND: signal ground
	8 -  CD: carrier detect
	9 -  RI: ring indicator


Hope this helps.

By the way I couldn't find this in any manual either. I had to look it up in
some internal notes that I have. I'll call this to the attention of the proper
documentation specialist(s).

	* I'm posting this because I think others may need the same
	info.  I've never found it in a manual.

The table posted by Rod Cerkoney is correct.

Negatory, and you can blame me; I'm the person who persuaded the lab to do
it this way:  The 9-pin connector on current Series 300 computers was cloned
(in 1984) from the one on the HP Portable (aka HP 110, HP 45710A).  It was
as much a standard as anything back then, and cables were available.  It has
neither the same sex nor the same pinouts as a conventional PC-AT port.

The pin-out information is documented under the 98561-66530 (Model 320 human
interface card) section of the 98561-90020 Series 300 Configuration
Reference Manual (8/85).  It may not have been documented elsewhere for
later models.  We need to address that.

Starting with the Model 375 we are switching to the industry standard male
9-pin connector and pinouts.  I will contact the keeper of the Workstation
Configuration Guide and ask that BOTH sets of pinouts be included.
