Firmware Version 3/4.31.37
2.9 INTERNAL 2-METER I/O BOARD
All RCU enclosures, excluding the Division 1/Zone 1 SMP Explosion Proof Enclosure, can support the installation
of one Internal 2-Meter I/O board. The basic functionality of the 2-Meter I/O board mirrors the functions of two
external FCMs but adding several additional input and outputs on that of an FCM. A 2-meter I/O board can
provide control of up to two meter runs.
