CNC Remote Panel Board CRPB II – OKUMA 1911-164
The 1911-164 is an electronic CNC remote panel interface board CRPB II (“CNC Remote Panel Board II”) manufactured by OKUMA, documented as a component of the OSP (Open System Platform) CNC control series, including OSP-5020, OSP-700, OSP-P200 and related variants fitted to OKUMA machining centres and CNC lathes. The board manages serial communication and the signal bus between the main CNC control unit and the remote operator panels (pendant, machine panel). The suffix II denotes the second design revision, featuring updated communication circuitry over the original CRPB release. The OKUMA spare part number is registered as 1911-164; no external accessories are included as standard.
The CRPB II board is the communication node between the CNC CPU and the operator panel: it transfers panel commands (spindle override, feed override, emergency stop, program selection) to the controller in real time and returns machine status to the panel displays. A failure of this board results in complete loss of operator panel response, inability to start automatic cycles or to intervene manually on the machine, rendering the machining centre fully inoperative until the board is replaced or repaired.
OKUMA Corporation is a Japanese manufacturer founded in 1898, one of the world leaders in CNC machine tools (lathes, machining centres, grinding machines) and the related proprietary OSP (Open System Platform) controls. Unlike many competitors, OKUMA designs both the machine and the CNC in-house, ensuring optimal integration but making electronic spare parts available exclusively through the official network or the specialist secondary market. Products of the OSP-700/5020 family are legacy / discontinued: available only as used, surplus, or through specialist repair.
