whole day, your average would appear to be about 12 seconds between
transactions, and using the chart above, you would assume you could safely run
16 terminals from one Base. But what about the peak time of 7:00 to 10:00,
when transactions are only 3 seconds apart? Running 16 terminals per Base
would cause significant delays during your peak time, extending the amount of
time it takes to do the same amount of work. The safer bet is to use your peak
time to calculate your average; in this case, you could efficiently run 6
Terminals on each Base without significant delays.
Each Base station can accommodate up to 16 terminals - as you can see, the
restricting factor is the number of transactions you need to perform per second.
If the number of Terminals you can run based upon the average transaction time
isn't acceptable, you need to add another Base station (or 2, depending upon
what an acceptable transaction time is for you) and split your terminals between
them. High volume systems probably require additional Base stations. Adding
an additional Base station requires another serial port(s) or even another host
computer in many instances. Only one Base station per serial port is allowed -
you cannot multi-drop or daisy-chain Base stations. Each Base station (and it's
associated terminals) operating in a given area must also be operating on a
different frequency. A common configuration has multiple workstations
running a network application, with each workstation running a Base station and
associated terminals on a unique frequency.
The great thing about the RF Worth Data R/F Terminal system is that you can
easily add additional Base stations at very low cost.
