Emerald-MM-8

The following information applies to all versions of Emerald-MM-8.

Digital I/O

Max Ports: 1 8-bit bi-directional port with programmable direction bit by bit

Digital I/O port requires direction to be set with dscDIOSetConfig() before use.

The configuration byte has the following format:

Bit No.	7	6	5	4	3	2	1	0
Name	DIR 7	DIR 6	DIR 5	DIR 4	DIR 3	DIR 2	DIR 1	DIR 0

Dir 7 - 0 0 = input, 1 = output

Serial Ports

8 serial ports with RS-232, RS-422, and/or RS-485 capability, depending on the model.

Serial ports have jumper-configured protocols, base addresses and IRQ levels. See the board's user manual for information on serial port configuration.

Serial ports on Emerald-MM-8 are not supported by Universal Driver.
