This eight-port async communication
adapter provides eight industry standard 16550-based UARTs using RS232 signaling levels. Each port provides the full set of
data and modem control lines configured for DTE operation.
All eight ports are available out the PMC front panel on J1 68-pin SCSIstyle connector. All eight ports are also wired to the
PN4 connector at the rear of the PMC, allowing connection to the VMEbus P2 connector for host processors supporting rear-I/O. These signals are carried on the “a” and “c”
rows on the P2 connector. There are other standard connection configurations for the P0/J0 (enhanced VME and cPCI) and the “d” and “z” rows of an enhanced DIN connector
Technobox P/N 5284 is a ROHS and Industrial temperature upgrade for the Technobox P/N 2229 and is a drop-in replacement. While the 2229 used a PLX 9052 bridge chip and is useable on 5V PCI signaling carrier cards only, the 5284 uses a PLX 9030 bridge chip allowing use with 3V or 5V PCI signaling carrier cards.
