Previous NI 5185/5186 Modules

Early versions of the NI 5185/5186 only support 50 Ω input impedance. If the front panel of your
NI 5185/5186 looks different from the front panels shown above, you may have an earlier
version of the device. Check the part number of your device to be sure:
• NI 5185 module part numbers 199363x-0zL and NI 5186 module part numbers
193537x-0zL (where x is any letter and z is any number) only support 50 Ω input
impedance.
• NI 5185 module part numbers 152962x-0zL and NI 5186 module part numbers
152961x-0zL (where x is any letter and z is any number) support both 50 Ω and 1 MΩ input
impedance.
