VK45 serial port

[TJ in CT]

I'm trying to find a drawing/wiring chart for the serial port on a vk45 I have looked around the internet and can't seem to find one

I'm trying to help a friend by building a cable for him and understand the PC end and have an understanding of handshaking

Thanks to all

I have a customer that has some of these Hitachi VK45's and I could probabally get it Monday, Here is a link in the mean time, (they also have a free single PC/machine) DNC program. http://www.cadem.com/ncnet/ncnet_dncdetails-41.htm

Thanks the link is about what i thought but its for a vk41 I hate to ask but if you can on monday just to be sure i would appericate it, TJ

I'll see what I can do, it is probabally going to be a standard RS232 25p 'D' conn. I think he uses the 3 wire (jumpered handshake) mode.

Thats what I thought but with a red wire in pin 1 I just want to be sure, thank you for your help, TJ

Is that pin 1 of a 9p D, or pin 1 of 25p? Pin one of the 25 pin type is usually ground or shield, and not generally used. On 9 pin D pin one is DCD.

Here is the VK45 serial port info, . I guess the VK45 port is not standard after all.
VK45___ PC
3------2 SD
5------3 RD
7------4 RTS
9------5 CTS
14-----20 DTR
15-----8 DCD
13-----7 SG
1------1 FRAME GND

Thank you for checking, I hate to ask 1 more thing, his book has a listingfor location 305 there is no table/location for 7 or 8 bits or even odd parity the is a listing for stop bit.
the 305 location has a table the showes differant baud rates but only one block for baud, am I to assume the right 4 bits are the hold baud rate setting or does the type of machine only work at 600 baud
I want to say thank you VERY much for you help, TJ

[Al_The_Man]

I will see what I can find out tomorrow.

Hi Al,
New on this Forum, machine and communication. I have a 1988 VK-45 with the Seike Seicos M2 controller and intend to use a 25 to 9 pin serial. Can you maybe help me? Please, please! I Need pin wire info, stop bit, parity, data bit, flow control, and Xon/Xoff character information if you should have it. You are truely the Al Man in my book, if you can help me.

Tnx a bunch.

E.T.

If you use the three wire cable,( XON/XOFF HS) and the VK has a 25pin D connector out to the front then, on the CNC side 6,8,& 20 are jumpered 4 & 5 are jumpered, on the 9pin 1, 4 & 6 and pins 7 & 8 are jumpered the 3 wire connection between D connectors:
CNC -----PC
2---------2
3---------3
7---------5
Set both ends to 9600baud 7 bits, even parity, 1 stop bit.
What communication program are you using?
Al.
