BB-USR604 Timer settings from 1 to 255 msecs are available. The default value is 16 msec. Select lower settings to correct response problems. TIMEOUTS The USB timeout is the maximum time in milliseconds that a USB request can remain outstanding. Minimum read and write timeout values between 0 and 10000 msec can be selected. - Page 23 RS-232, RS-422 and RS-485. Most new PCs have eliminated RS-232 ports as standard features and RS-422/485 was never a standard feature. As a result USB to serial converters such as the BB-USR604 are often necessary to communicate between PCs and legacy systems that implement Modbus protocol.
