We have successfully used the RB-530 with E-Prime where the RB-530 was configured to emulate the PST Serial Response Box Model 200A at 19200 Baud. In this case, the DIP switch settings we used were (as seen from the back of the unit):
up-down-down-down (1000)
So far, we have been unsuccessful in configuring the RB-540 for the same purpose. Based on information in the thread http://community.cedrus.com/showthread.php?t=2115 it appears that all four DIP switches are used on the RB-540 whereas only the first three were used on the RB-530.
What is the correct DIP switch configuration for the RB-540 to emulate the PST Serial Response Box Model 200A at 19200 Baud?
Thanks,
Steve
