Accuriss Communications
Communications to the Accuriss is possible with any RS485 compatible communication device
and any commonly available terminal program. Most computers have either an RS232 or USB
port (sometimes both). USAutomation offers software drivers for both on our web site or in our
Starter Kit. Commercially available USB to RS485 and RS232 to RS485 converters will allow
communications with the Accuriss from most computers using only a compatible terminal
program.
Also available as a software tool is the Accuriss Terminal software, which is available as a no
charge download from our web site, or it is included in our Starter Kit.
