Overview PC-500 user’s manual
Industrial I/O using EZ I/O
The PC-500 is supplied with 24 lines of industrial I/O, using the Octa-
gon EZ I/O digital I/O chip. Each EZ I/O line is programmable as an
input or output. The lines are 5V compatible and can sink and source
15mA. The EZ I/O port can drive the Octagon MPB series opto-isolation
module (Opto 22, G4 style) racks directly, controlling AC and DC loads
to 240V at 3A.
Speaker, keyboard, and mouse ports
The speaker connector is PC compatible and is a standard feature. The
keyboard controller accepts an AT style keyboard and has a PS-2 type
connector. The keyboard port is standard. The mouse port is optional
and conforms to the PS-2 standard. Neither the keyboard nor the
mouse are required for operation.

Mouse port not included optional
PC/104 16-bit interface
This interface is a standard feature on the PC-500 and accepts an 8- or
a 16-bit PC/104 expansion board. PC/104 expansion boards are avail-
able from several manufacturers. As many as three PC/104 expansion
boards may be stacked on the PC-500.
Ethernet
The PC-500 provides a 10Base-T Ethernet port, located at J9. This
interface is a standard feature on the PC-500 and supports the IEEE
802.3 Ethernet standard. The Ethernet controller IC chip provides the
following:
n
16-bit ISA interface
n
4 KB on chip buffer
n
Integrated 10 Base-T transceiver interface
n
Four LEDs for status and diagnostic purposes
The PC-500 Ethernet interface supports the 10Base-T physical inter-
face. This port operates at 10 MHz and uses twisted-pair wiring cable,
which is built in a star configuration. The 10Base-T physical interface
terminates at the standard, 8-position RJ-45, latching phone jack and is
vertically accessed.
SCSI
The PC-500 has a SCSI-2 host interface, located at J12. This device is a
16-bit ISA bus compatible part and has a sustained data rate of 10 MB
per second in the fast SCSI-2 synchronous transfer mode. It also has
parity generation and checking, noise filters, a low power mode, and ISA
bus RAM buffers.
