Replacing HH tnc 151 with HH tnc 155 , monitor output is different ??

[zebbguy]

Hi all i know trying to Replacing Heidenhain tnc 151 with HH tnc 155 , monitor output is different ??

i think they are both monochrome output ?

Tnc 151 has an ampthenol connector
Tnc 155 has an RS232 9 pin

ive cut and soldered the ampthenol connector onto the tnc 155 as follows

cable/connector tnc 155 board ---- Ampthenol cut from tnc 151
Blue - Blue
Red - Red
Green - Green
Yellow - Yellow
Brown - Brown

so ive just matched these up for example gn-gn / 0v-0v / ge-ge

on the tnc 155 board there where two pins unused ive soldered these and connected them as on the 151 board

its not working at the moment the screen wont come on or display anything

We have got somewhat of a screen working, i have relay ext voltage missing . this is not due to emergency stops its either parameters / or ./ wiring to the control

The Drives will come on with a low buzz

Y axis slowing counting up though ?

More testing

All sorted the output of the tnc 151 power the monitor via the controller ( 11V ), however the tnc 155 monitor output had a separate power supply to the monitor and must have 12v so connecting the pins on the board only gives the monitor 11v which is not enough

i wired a separate 12v 2a power supply worked fine
