3.4 Digital Input/Output

The ME-5100 has two 16-bit digital-I/O ports and a number of con-
trol lines. When operating in single mode, the two ports can be
configured, independently of one another, as input or output. The
direction of the ports is defined in software. When operating in
streaming mode, the direction of the ports is specified by hard-
ware: port A is the input port, while port B is the output port.

In streaming mode, ports A and B must share the bandwidth for
the data transfer between the board and the PC. This depends on
the configuration of your computer - a total data throughput of up
to 30 MS/s is realistic (see also Table 4 on page 23).

Please read chapter 4.1.1 from page 24 for programming the dif-
ferent operating modes.

3.4.1 Digital Inputs

When wiring the inputs, note that the voltage level must be ob-
served (see the specifications on page 32) and that a reference to
the PC ground (GND_PC) must be established (see Diagram 6).
