The IS215VCMIH2B is a VME communications interface card manufactured by General Electric as part of the Mark VI family for gas turbine control systems.

The VME Bus Master Controller (VCMI) board serves as the communications interface between the controller and I/O boards, as well as with the IONet system control network.

The VCMI also acts as the VMEbus master controller in the control and I/O racks, managing the IDs of all boards in the rack and their associated terminal blocks.

Through the J301 backplane connector, the VCMI card receives analog and digital feedback on power status.

There are two versions of the VCMI board: VCMIH1 and VCMIH2.The board has four port connections on the front panel.

The board has four port connections on the front panel, including three IONet connectors and one serial port. There are three LEDs above each IONet connector.

“TX”, ‘RX’ and ‘CD’ are the labels on them. The panel www.cniacs.com also contains four LEDs labeled 1. 2. 4. and 8. as well as LED indications labeled Run/Fail/Status (located above the pushbutton reset switch).

The panel attaches to the motherboard using screws.
