We using 1771-DB in our PLC-5 chassis. We want to upload from 1771-DB using 1746-PBase software, I have difficulty to get connection to 1771-DB. How to define pin assignment for communication cable?
Thank you
Dave

hello Dave

well u will be using a 9-pin (computer side) to 25-pin (DB module side) cable

the pinouts will be tht of a straight cable

ie:-
9-pin side<--------------------------->25-pin side

2<--------------------------------->2 (TX)
3<--------------------------------->3 (RX)
5<--------------------------------->7 (signal ground)


this configuration will work fine. u can use PBASE to connect to ur DB module or Normal windows Hyperterminal can also be connected to DB module

How to perform download/upload from PBase software or Hyperterminal?
My computer with windows 2000 server, could i use this OS?
Thank you
Dave

hi there dave again

unfortunately u cannot use new OS such as win2000 or win98 to run PBASE - i have tried tht a lot but it was waste

instead u can use DOS or WIN95
win95 can be ur best choice.

so hunt for a machine which has win95 loaded into it , load PBASE into it and GO-->connect to ur DB module

I have windows 98, how if I boot computer to dos mode? Could we run the PBase? Or you have any Idea?
Thank you
Dave

When the pc boots, hold down the shift key until the win98 menu appears, then select the command prompt optoin.
Pbase is prette small, you should be able to put it onto a floppy if you have one. Just boot from a boot up disk, then put the floppy with Pbase in and run it. Do this if you don't have Windows98.

its mean that we restart computer in dos mode?
Thank you
Dave

Whatever you can do in 95, you should be able to do in 98. The OS's after W98 don't have a boot-in-DOS mode, so they would make PBASE difficult if not impossible.

I have never tried the holding down shift method, I have always hit F8 when the computer first starts booting from the HD. It is sometimes a bit tricky to hit it at the right time, so maybe holding down shift would be better!

You can set up windows to always go to the "boot menu" before going into windows. I'll have to find the book I've got that tells how to do it. I keep meaning to do this, as often as I boot up in DOS.

I like to display a menu option when booting a WIN98 machine giving me the option to boot into windows or exit to DOS. This method is done by creating a .bat file with the following lines in it. Then run the batch file from your autoexec.bat file found in the root directory.

I usually call this batch file startmnu.bat therefore I would add the line C:\startmnu.bat to my autoexec.bat file.


@echo off
:start
cls

I have to connected to 1771-DB using PBase software and re-start in dos mode, but I found the message:
" Com1 not open" then "module not responding"
How to solve this problem? If I want to upload/download using Hyperterminal, how to setup and instruction to upload/download?
Thank you.
Dave

Hyperterminal Setup

First you need to set up the correct communication setting, which would probably be something like: 9600 Baud, 8 Bits, No Parity, 1 Stop Bit, None

Now once you are connected typing LIST at the command prompt will list the program, essentially an upload, just copy the text and paste to text file.

To download click on the settings tab in connection properties, then click ASCII setup, depending on the speed of the computer you may have to add a line and character delay. I generally always use a line delay of 500mS. Then under Transfer on the Menu Bar select Send Text File, this should download to the module.

hi dave

if ur running pbase from dos on a windows 98 machine, make sure that u have killed the RSLINX service from startup.

then boot to DOS and try to connect to DB module using PBASE

try this i think u will get success
