Hello
I have a SCXI-1303 Thermo block that I use with a SCXI-1102b module.
When this unit first arrived here, it had a network of pull-up and bias resistors from the factory; Somewhere along the way, a different wiring scheme was needed and they were removed and lost (not by me).
I'm unsure as to whether or not I can purchase the 10M ohm resistor networks from NI or not, sales was a bit blurry on their response.
I would be more than happy to wire up my own banks of resistors but am unsure as to the relationship of each of the sockets to what parts of the resistors... I know that RP1-4 are the pullup network, and RP5-8 are the bias, but as to what each pair does--I'm lost.
A schematic or wiring diagram of the 1303's printed circuit or pinout for the resistor bank sockets would be so helpful!
