Chapter 9 SC-2057SC-205X Series User Manual9-4 ©National Instruments CorporationIf the SH96-96 is connected to the VXI-DIO-128 connector labeledINPUT, the SC-2057 will provide access to ports 0–7. If the SH96-96 cableis connected to the VXI-DIO-128 connector labeled OUTPUT, theSC-2057 will provide access to ports 8–15.Note The two 50-pin connectors on the SC-2057 do NOT supply the two sets ofhandshaking lines normally found on a DIO-32F connector. The VXI-DIO-128board does not have the handshaking circuitry that is available on the DIO-32Fboards. Therefore, these lines are NOT provided by the SC-2057. Any accessoriesneeding these handshaking lines will NOT work connected to the VXI-DIO-128 viathe SC-2057.There are also four voltage supply connectors on the SC-2057: J3, a +24 Vconnector, which can supply +24 V ±10% at 0.5 A; J4, a +12 V connector,which can supply +12 V at 0.5 Amps, and J5 and J6, two +5 V connectors,which can supply +5 V at 1 Amp. The total current draw from either orboth of the +5 V connectors must not exceed 1 A.Warning Under no circumstances should you connect these +5 V, +12 V, or +24 V pinsdirectly to ground or to any other voltage source on the VXI-DIO-128, SC-2057,or any other device. Doing so can damage the VXI-DIO-128, SC-2057, and yourVXIbus system. National Instruments is NOT liable for damage resulting from sucha connection.Figures 9-2 through 9-5 illustrate the output connections of the signalconditioning accessories to the VXI-DIO-128 and SC-2057 and thenecessary cables and accessories.Figure 9-2.
