RE: DCS300

Hi Angela:
We have done many RF installs with Teklogix equipment (disclaimer: we are
resellers), and their hardware words as you describe.  You have a controller
that talks TCP/IP back to the AS400 and the controller maintains the
connection back to the 400.  However, each handheld is a terminal on the
AS400 and basically does 5250 emulation.  So, writing code is simple, you
write for a smaller 5250 screen.  The controller handles the conversations
to the various base stations (radios).  We have one customer that has
wireless devices talking directly to the AS400 via an 802.11 access point,
but has a huge problem when the units go out of the coverage range, the 5250
sessions become orphaned.  The advantage of the controller solution is that
the controller maintains the conversation with the 400 and if the RF
terminal goes out of range, it knows how to pick up the connection to the
device without losing the connection back to the AS400.
Let me know if you have any particular questions.

    Hi all,

 

    We currently use a bar code scanner from intermec but we use a "middle
man" concept where the data is sent from the RF devices to a PC,
validated against the as/400 and then sent to the as/400.    We would
like to get rid of this middle man concept.   I know there is a dcs300
controller that will allow the scanners and as/400 to talk directly.  We are
looking at purchasing a used one and I guess trying this out as a "proof of
concept"  that this will work this way and is just as reliable
or more than the existing way.   This will allow us to bring the
programming in house since it is just a 5250 RPG programming.  

 

What I would like to know is anyone using this and what do you think of this
way.  I know the current technology is to move forward with the 2.4 mhz from
the 900 mhz.  We will move that way eventually as we will be doing another
RF project in the next year and the new section will have
2.4   but for now if we could just cut out the middle man pc we would be
happy.  Then eventually upgrade this section,  but the programming would
already be inplace it would just be hardware.

 

If anyone has any thoughts/ comments let me know.

 

Thankyou!!!!
