The mPCIe-ICM Series of PCI Express Mini Cards from ACCES I/O Products are designed for use in harsh and rugged environments including military and defense applications. The isolated serial communication cards measure 30 x 51 mm and feature four or two ports of isolated RS232 communications. 1.5 kV isolation is provided port-to-computer and 500 V isolation is provided port-to-port on all signals at I/O connectors. Tru-Iso port-to-port and port-to-PC isolation is also provided. Designed using type 16C950 UARTS, the cards use 128-byte transmit/receive FIFO buggers to decrease CPU loading and protect against lost data in multitasking systems. Provided ±15kV ESD protection on all signal pins protects against damage to sensitive electronic devices due to electrostatic charge.
