Connecting the LCD Display - Verification

[Effayy]

Hi guys,

I just wanted to bounce what I'll be doing off you to make sure that what I'm doing is correct.  I don't want to damage the display so I'm being nice and cautious.

The manual for the display I have is located here:

From what I can gather from the document, I will be attaching 3 wires (I bought blue, black, and red 22 guage wire for this):

Blue wire connects to Pin3 on the DB9 and "SER" on J1

Black wire connects to Pin5 on DB9 and "GND" on J1

Red wire connects to the red wire connected to one of the molex connectors coming from the PC's PSU, and "5v" on J1

The diagram at the top of Page 3 in the manual shows a faint line connecting pins 1,6,4, and pins 7,8.  I don't believe it affects my cable, correct?

Sorry for being a bother with this, as I said before I'm just being extra cautious to do it correctly.

Here's a pinout reference of the port:

Pins 1, 6, 4 are DCD, DSR, DTR - I guess the idea there is that when a communications program on the PC host opens the port, it'll raise DTR, and the wire connections will raise DCD and DSR as well, ensuring that the comm. program is made to believe there's a communicating device on the other end of the line.

Pins 7, 8 are RTS/CTS, the hardware flow control lines.  Those are connected together so that if a comm program attempts to use hardware flow control, it'll always get "clear to send" any time it wants to send something.

So, yeah, the idea here is that you'd make those connections.  Whether you need these connections depends upon your software.  It shouldn't be a problem to hook 'em up even if you don't need them...
