OSDP, Wiegand & End of Line Resistors
I hope that this video demystifies the need (or no need) of a resistor for OSDP communication when attempting to reuse Wiegand cabling --- and for new installs that use the proper OSDP cabling.
I'll be doing an episode next week on the 1k pull down biasing resistor too. The full repository is on YouTube if you're looking to learn more about OSDP -- (150) OSDP - YouTube
