Hello.

I'm just started working with RV-M1 robot at my university for my thesis.
I can connect it in parallel port, but since I need to use the feedback position from the robot, I need a serial connection.

The problem is, I can't connect my robot with the serial cable I purchased from local store.
I had used the original program and the program from the denford robot
Just want to make sure, the serial cable is from DB25-DB9, right?
And I just need to turn off the teaching box, setting the com port at the drive unit and match it with the com port setting at the PC, then connect the DB25 to drive unit and DB9 to serial port.
Or is there is special configuration for the cable?
Can someone post the proper connection from DB25-DB9 that used in this robot. I read on the manual there is signal respond requirement. Is it important and how to set it if I make my own connector.
I'm totally new to robotics and there are noone with experience with this robot in my university.

Thank you for your reply.

Enter as much information about your CNC hardware and software as you can - it makes it easier for everyone to know what you're talking about then.
Normally the RS232 port on a PC is 9-way...25 way is usually a parallel printer port.

The 9 to 9 way cable shown here will work with most RS232 devices:

Thanks for your response. The problem is the drive unit port says RS232C but it is not DB9F port, but DB25F port instead.
Therefore it is impossible to connect it with normal RS232 cable.

Oh thank you very much.
I hope this configuration works for me too.
:D

We have made lots of these RS232 cables in the past and we know that they work OK

Ok, I have made the cable.
When I use it to connect robot using Mitsubishi Com Server, it got connected, but everytime I write a program and send it, it become error (long beep, drive unit error led on and led 1-5 inside off,
Do you have any suggestion where is the source of my problem?
If I use the Robot communicator from den ford, it got error too, and I don't understand setting com port with Qbasic, since I always get bad file name problem when I use this line:
OPEN "COM1: 9600, E, 8, 2" FOR INPUT AS #1

My SW1 setting: 01100001
My SW2 setting: 01001111
My SW3 setting: 00000001

Do I messed up with the setting?

I already set the com port correctly according to the Denford mitsubishi communication centre.

Thank you for your response.

Ok, I got it figured up.
I look into the original connection that supplied from manual then convert it to DB 9 connection
Thank you for your suggestion.

For future user of RV-M1, I suggest you to use this connection instead.
At least this connection works for me
DB 25(Male) DB9 (Female)
1 METAL(casing of DB9) grey
2 2 red
3 3 orange
4 8 pink
5 7 white
6 4 yellow
20 6 brown
7 5 blue

That is the working connection from the drive unit to my PC that I use.
Don't forget to set the flow control to RTS. After I set it, i got it working because even with same cable, without that setting somehow it failed to works.
