The 1504 offers a six-slot passive backplane with three available expansion slots, including one full-length ISA, one full-length PCI and one half-length PCI. The unit includes a 10/100 Base-T Ethernet controller, two USB 1.1 compliant ports, two RS-232 serial ports, parallel port, and PS/2 port for mouse and keyboard connections. The onboard video port uses up to 32 MB of system RAM. An Intel Celeron 1200 MHz processor is standard, while a Pentium III 1.26 GHz processor is optional. “Factories are becoming cleaner and more environmentally controlled,” says Ralph Damato, business unit manager of Industrial PC Products at the vendor. This means that traditional heavy-duty industrial PCs are not always needed, he says. “With the 1504, industrial installations now have a lower priced industrial solution without resorting to a less rugged commercial PC.”
