"We did not invent the product, but we made it better" is a famous
quote from BASF and we feel the same with our new RS-232 to USB converter kit
for Sartorius Balances exclusively found only at Precision Weighing Balances.
Your source for deep discount prices, operator of the world's most informative
website at www.balances.com dedicated to balances, scales and weighing accessories
and your Authorized Sartorius Dealer.
The balance and scale industry seems to lag the technology curve so we went
searching to give our customer the products they ask for - a balance with a
USB port at a reasonable price. Many of the balance manufacturers are
out of touch with the times and have their balances designed with a standard
RS-232 port to interface the balance with a PC. The problem is almost
every laptop comes outfitted with a USB port and not a serial RS-232 port.
Those computer gurus savvy enough to deal with integrating a serial device attached
to a PC always needed to deal with IRQ conflicts. Choose USB and say goodbye
to IRQ and Com port conflicts.
Our RS-232 to USB converter kit follows the www.balances.com
business philosophy. Deliver the goods the customer wants even if you
need to work outside of the box and find another vendor to supply the components
to make things happen. Of course the solution also has to incorporating
KISS (keep it simple stupid). Yes - USB is the easiest way to interface
a peripheral with a PC.
Many of today's new laptops are often equipped with USB ports only,
and have no RS-232 interface. The same applies increasingly to desktop
computers as well. This means more and more of our customers are
confronted with the issue of finding a cable they can use to connect their
Sartorius balance or scale to a computer. The fact that standardized,
commercially available cables are not compatible with the pin assignments
in Sartorius equipment does not make things any easier.
Some scales on the market offer you the ability to purchase an optional
module to providing you with either an RS-232 or USB interface (examples
would be the Ohaus
Scout Pro Series and the Acculab
Vicon Series). This module cost around $75 and the problem is
you need to decide do you want RS-232 or USB, but not both.
Our USB to Serial Adapter kit for Sartorius Balances
(part # SARUSB) offers you the best of both world for less.
If you want to interface the Sartorius Balance with a RS-232 serial port
you simply disconnect the 1 foot RS-232 to USB cable. Simple, Easy,
Flexible and Low Cost is the name of the game with Precision Weighing
The USB to Serial Adapter
kit for Sartorius Balances (part # SARUSB) provides the connection
between USB and the RS-232 serial port of the Sartorius balance.
The kit consists of two cables daisy chained together. The
first cable is the specially
configured RS-232 cable (commercially available cables are
not compatible with the pin assignments ) 5 feet in length mated
with an RS-232 to USB type A connector with a cable length of 1
foot. Together your total cable length is 6 feet.
Supports automatic handshake mode
Over 230kbps data transfer rate

96 byte buffer each for upstream and downstream data flow
Please note this cable will not work with All AC, BP, LC, MC

A virtual COM port is set up on the computer using the driver
that comes with the cable. The application program running
on the computer does not detect any difference between this
virtual COM port and a physical COM port, because the actual
functions are identical.
