This board will accept one 64-point Cirris Adapter board or two 32-point Cirris adapter boards, and show results as a 64-pin header numbered 1-64 on each bank. The CableEye software does not compute the board or cable signature or automatically identify which Cirris board is connected. Use the PinMap software, to obtain a proper graphic and pin numbering. Most Cirris-made boards are numbered so that the test point number corresponds with the connector's pin number, so the pin numbering shown on the 64-pin header will be correct even if the graphic is not. You mau use this board with CableEye HVX systems. It has been certified to operate at test voltages of up to 1500vDC and 1000vAC assuming that suitable-rated Cirris board is also used. Set of two boards.
