Page 13: Connecting An External Power Supply
Connecting an External Power Supply You can optionally connect an external power supply to the NI 9361 to provide current for the devices that you connect to the module. Install a 2 A maximum, fast-acting fuse between the external power supply and the Vsup terminal. - Page 14 You can connect single-ended devices, such as TTL or CMOS to the NI 9361. For single-ended connections, connect the device out to the DI+ terminal on the NI 9361. Do not connect the DI- terminal on the NI 9361 for single-ended connections.

- Page 16 NI 9361 An open collector device does not actively drive the signal high and relies on an external pull-up. The NI 9361 provides a 5 V pull-up on each DI+ pin that can be enabled individually to pull the signal high.
- Page 17 You can connect differential devices to the NI 9361. For differential connections, connect the positive device out to the DI+ terminal on the NI 9361 and the negative device out to the DI- terminal on the NI 9361. NI 9361 Getting Started Guide | © National Instruments | 17...
- Page 18 – DI0– NI 9361 The NI 9361 measures the difference between the DI+ and DI- terminals to determine if that difference is greater or less than the digital logic levels. If the difference between the terminals is within the input high range, the channel registers as high. If the...
