M4 RS-232/RS-485/RS-422 Data Operation
The Mini4 System provides 4 independent channels of RS-232 data and 2 channels of either RS-485 or
RS-422 data (jumper selectable). All data channels support at least 115.2 Kbaud, with the RS422 channel
capable of up to 2.5Mbps. Refer to the Jumper Configuration section for specific jumper definitions and
settings for the Video Input and Video Output board
M4 RS-232 Data Channel Selection and Operation
The 4 channels of RS-232 are optically isolated in pairs (i.e. channels 1&2 share a common isolated
power as does channels 3&4). There are no baud rate jumpers to select for RS-232 operation. The
channels are simply time sampled at 25 mega samples per second (Msps). The maximum RS-232 data
rate is governed by the slew rate limiting on the RS-232 driver chips themselves.
M4 RS-485/RS-422 Data Channel Selection and Operation
The 2 RS-485/RS-422 channels can have several possible configurations. The configurations are
selected by placing jumper shunts on several jumper posts. The RS-485/RS-422 channels have optical
isolation (i.e. channels 1&2 share a common isolated power as does channels 3&4).If the channel is
selected for RS-485 or RS-422 operation, then the data rate does not matter. The board accommodates
all data rates up to 2.5 mega band.
