7204: Great reliable product
Happened to find the User Manual for our pair of 7204 Ultra 485+2.PCI units and thought would provide a little feedback. We purchased these in 2005 for use in our product testing. One configured for RS422 and the other for RS485 and both used at data rates from 9,600 to 115,200bps. They are used nearly daily and have been so reliable that they are our standard.
