Another Communication problem

Post by Wardy » Sun 21 Jun , 2020 13:12 pm

Hi All
I have bought a microrouter year 2001
I am having serious problems with connecting it to VR5.69 milling latest software
I have now bought 2 leads from USB to RS232
I am running WIN 7 64 bit
I have installed the ABB 64 bit motion control drivers
I have set the machine up as router DENSTEP
And still no avail
The board in the cabinet is showing 8
Which reading up its ready to go
I have checked the baud rate etc on the the device panel on the laptop
The machine parameters are the same
So I am now at my wits end
I am a engineer so I am a bit basic on the required needs for pcb boards and wiring im more mechanical
Can anyone help

what cable do you have running from the RS232 to the machine?
If you have a search there is a pin out that is to run direct from 9way on a PC to the 9way on the board.
Have you selected the correct machine in VR milling? You don't say which board you have, does it have the red 7 seg or the green 7 segment display?
These is a bit of diagnostics software on the software cd I can never remember what it is called, It might be easy upgrader, this checks the machine, you could try running that as that might talk.

Thanks for getting back to me Pete
I am going out of my mind trying to connect the laptop to the machine

I have the black lindy cable with a 25 pin rs232 in the back of the router
coneected to that I have the grey lead that also came with the machine that takes it down to 9 pin
and then I have the USB connection to that in the laptop
I have set it as DENSTEP
As it has red 7 seg
the laptop is seeing the router as when i unplug it at the back of the router the laptop bings
its just not talking to it
any ideas

What is the version of E Prom on the Dendtep control card? If it's 2.0 05 2.1 then it should be ok for VRMilling but it may be a Dos chip.

What Com port do you have the USB to serial adaptor set to? I would suggest setting it in advanced to between Com 1 & Com 5 if possible.

Have a read of this recent thread . If your control board has the NiMH battery it may be the same issue of it leaking and causing comms issues.
