Edwards EST IOP3A RS-232 Optical Isolator Card

The IOP3A is an optically isolated RS-232 card that electrically isolates the power between the CM1(N), CM2N, FCC, 2-MCM(N), QuickStart, and 3-CPU(1). The IOP3A also provides power for use with short haul modems and fiber optic drivers. The IOP3A is a ½ size footprint card that is mounted in an enclosure adjacent to the CM1(N), CM2N, FCC, 2-MCM(N), QuickStart, and 3-CPU(1). The module is powered by the system power supply that provides battery back up. The IOP3A, through it’s on-card regulator, generates isolated power for the RS-232 drivers. The on-card regulator also provides isolated 12 Vdc power for use with external modems and drivers. Two RS-232 ports are provided that operate parallel with each other. A DB-9 connector is available for a con-venient point of connection for a system program download cable.
