I always use port 0 with a nul modem adapter, then match your speed with what's on the dip switches on the front of the card. 8n1

meehan

with the null modem adapter do i use a patch or crossover cable? and when i open hyperterminal and hit connect what is supposed to come up? is it supposed to ask for a login or no... i have it set up 9600 8n1 on com but im not sure if my null modem is working correctly. do you know if there is a wiring diagram for making a new one anywhere?

i really appreicate it.

You use a straight through cable with the Nul Modem adapter, when you hit enter it should print something then you type LOGI return and it will ask for the password

meehan

still cant get it to connect.

Lets do it together.

Assuming The PBX is powered ON

Grab the cable TTY 0 (or it may say PORT 0 (25 Pin connector))
Connect your Nortel NULL modem to that cable. (25 PIN connector)
Now connect a cable to the other end of the NULL modem and then connect the other end to your computers Com 1. (generally a 9 pin connector)

Once all of that is connected.
Switch your PC on.
Log in to windows.
Open Hypterminal.
It will ask for a new Connection Name.
Type in PBX
Click OK
A new window will appear.
At the bottom of this window, it says "Connect using"
Click on the drop down box and select COM 1
All other boxes on this window should now be greyed out.
Click OK
A New window will appear.

At the top it says "BITS PER SECOND" select 9600
The next drop down box is labeled "DATA BITS"
select 8 from the drop down box

The next drop down box is labeled "PARITY"
select NONE from the drop down box

The next drop down box is labeled "STOP BITS"
select 1 from the drop down box

The next drop down box is labeled "FLOW CONTROL"
select HARDWARE from the drop down box

Click OK

Hit enter.

Do you get TEXT back? if not double check your cables.

Nothing works.
Im not sure about the wiring on my my rj45 to DB9 connector that connects to my pc's com port, i bought it and made it.

all the other cables came with the system..

the pin out i used is

1-blue
2-orange
3-black
4-red
5-green
6-yellow
7-brown
8-white
9-N/A

is this correct?
i have extra ones i bought incase its not.

How about you forget about the RJ 45 cable and use a proper db25 to db 9 serial cable before doing anything fancy with ethernet cables..get this working first because right now you have no idea if the pabx is working or not.

meehan

i tried a db25 to db9 cable connected to the modem eliminator to port 0 and tried it, and still got nothing. i have 1 phone connected to the pbx and when i hit the program button i get options for language, contrast, ect. so i know it works that far.. i dont know what else to do. i wish some one could come and show me what im doing wrong.

Bigsy

have you tried without a modem eliminator on, the cable itself maybe nulled already, do you get anything on ur terminal screen at all when pressing enter, if so you may need to change your com port settings, maybe try E-7-1, also make sure that the PABX 3 port cable Aka SDI Cable or Octopus cable properly connected to the PABX.

if 0 doesn't work maybe try port 1 or even 2, maybe tty 0 and 1 may be deleted. who knows I'm just throwing out ideas, but unless u can get it working on a serial cable i wouldn't be bothered trying to figure out the pin outs for Ethernet cable because it might be a waste of time.

If all else fails perhaps try to use a Tranciever if this system has any configuration at all it might still have the default ELAN IP Address, if this is the case you may be able to RLOGIN into it (Long shot but hey might be worth a try)



thats all i can think of at the moment.
