Chapter 5 Cables and Accessories
NI SH37F-37M Cable
The NI SH37F-37M cable is a 37-pin shielded cable that provides direct connection to 37-pin
651x devices. This cable uses 26 AWG wire that has a maximum current rating of 1.2 A per line.
Some devices that can be physically connected to this cable have current ratings that exceed this
limitation. The NI SH37F-37M cable is not intended for use with hazardous voltages (greater
than 60 V DC, 42.4 V peak, or 30 V RMS).
Ensure that the DIO device does not exceed the maximum current rating by evenly distributing
the current among the VCC pins on the NI 6516 and NI 6518 devices, or among the GND pins
on the NI 6517 and NI 6519 devices. For more information, refer to the Distributing Current
(NI 6516/6518 Only) section and Distributing Current (NI 6517/6519 Only) section of
Chapter 4, Power Connections.
For quick connection to the I/O connector, use the National Instruments CB-37F terminal block
with the NI SH37F-37M cable.
Accessories for 100-Pin Devices
National Instruments offers the following products for use with NI 6511/6512/6513/6514/6515
devices.
For more information about optional equipment available from National Instruments, refer to the
National Instruments catalog or visit the National Instruments Web site at
ni.com.
SH100-100-F Cable
The SH100-100-F cable is a 100-pin shielded cable that provides direct connection to 100-pin
devices. For quick connection to the I/O connector, use the National Instruments SCB-100
terminal block with the SH100-100-F cable.
R1005050 Ribbon Cable
The 100-pin R1005050 ribbon cable splits into two 50-pin cables for direct connection to one or
two 50-pin accessories. The 100-pin connector that joins the two cables plugs into the I/O
connector on the DIO device.
For quick connection to the I/O connector, use the CB-50 or CB-50LP terminal blocks with the
R1005050 cable.
