Scale Interface
B Bauer
I'm currently working on a project that requires interfacing to a USB
connected scale on the PC. The shipping application they're using runs
in a 5250 CA window and they'd like to have the weight from the scale
automatically populated to a field on the 5250 session. I'm planning
on writing the scale interface in C# and run it as a service on the PC
but I think the biggest challenge is getting the value into the 5250
session.
Another thing I was wondering is if I could configure the scale as an
AS/400 device (Longshot) something like a CA printer session. Then I
could just mod the RPG program to access the device.
Has anyone had experience with doing something like this?

Hi Brad,
we have connected the scale as "alternate input" between the PC and the
keyboard. So when we push the "get data"-button on the scale, we get the
data as they were entered on the keyboard. So the only thing we had to do
was to modify the input-field on the AS/400-Screen to the same format as the
data from the scale are transmitted.
Before pushing the scale-button, the user has to start the right application
an put the cursor on the right field.
That is the simpliest way, and no need to write interface-applications (if
your scale support this way).
Good luck

You can use a keyboard wedge connected to the scale but you'll have to
use RS-232 instead of USB.
The type of scale is a big factor. I'm currently working on automating
sending a weight from a Avery Weightronix E1110 to a Compsee Turbo
wedge which feeds a 5250 session on a Computer Lab thin client. I'm
99% done. Through the "'autoprint" function on the scale, it sends
the weight with a CR /LF appended to it when the target weight is
reached, so no operator intervention is required.
We have a similar process working on Doran scales connected to
keyboard wedges and thin clients on ten final assembly lines.

You can use a dataqueue where the scale interface will put the weight
and the 5250 program will get it.

You can configure an ascii device on a RS232 port, as400 do not support USB.
Or you can work with the scale inside a SPECIAL device file handling
program.

Here is an inexpensive $35 program.
Load it on the PC and it will sit and listen for the scales to send
the weight, then it send the information to the keyboard buffer. They
also have a version to listen for TCP/IP data.
Assuming the cursor is always in the input field on the screen it
works fine.
