- Four RS-422/RS-485 or RS-232 data I/O portsThe SPE4 is a SY/MAX register rack mounted module with five ports.
The SPE4 is functionally similar to a NIM, with five serial ports instead
of two, and without a blue hose connection. Two versions of the SPE4
are available: the SPE4-1D, with four RS-422/RS-485 ports; and the
SPE4-1S, with four RS-232 ports. Both versions also have one powered
(+5V) SY/MAX RS-422 port. When configured in RS-485 mode, the
ports of the SPE4-1D are 2-wire and 4-wire compatible. For stand alone
operation, the SPE4 can be powered by the Niobrara clip-on
