New CPU8 - LAN / Serial Connection

[junoooni]

I have a new ACT28 with 2 x CPU-8's and 2 x IO2N boards and each CPU8 is connected to 1 x IO2N board with a weird board in front... my question is, how do i get access to CPU8 to configure IP and connect to customer network? i have installed CPU7 once but it came with a CBRMA board but this time i didnt got it.... is there any new connectivity?

nope you need the cables on the backside and the cbrma connectingbox

I have got a BRMA box and a cable to incterconnect both CPU's (3BA28041AA), another cable (3BA28040) one end of it is marked with COM,ETH,VM,FD i have fixed this end on top of interconnection cable on main CPU and other part is connected to BRMA...then i have (3BA58074) which I have connected on top of backup CPU and then i have 2 x 33BA28208, where do i connect these?

i have powered on my system but still cannot take serial connection to it, any help will be appreciated

I am unable to get Com connection... neither i can see any light on CPU8...only IO2N boards have CPU lights blinking

[alexeik]

hi alexeik

i connected using the document you referred but there isnt any activity on any of COM ports on BRMA

[alexeik]

hmm
do you use a "nullmodem cable" for the connection from the brma to the PC?

[junoooni]

Yes.. i m using a null modem cable

[alexeik]

then i have no clue... should work

Finally it turned out that there was a lot of CPU-8 which BIOS wasnt compatible with Windows 10... ended up using an XP PC and everything worked fine
