I believe this to be correct. According to the circuit topology and values
I’ve deduced, there is a current source of 15.38mA, derived from a +8.4V
supply rail
|

This indicates that sensors should try to draw no more than 10mA and certainly
not more than 15mA in order to get the best performance.
|
Experiments completely second that, see this V/I curve I measured while
preparing my GP2D12 interface.

| I've been looking into the interface of the RCX sensor port, as well as studying available information. This page from Stef Mientki suggests that the port uses a current source: (URL) believe this to be correct. According to the circuit topology and (...) (19 years ago, 7-Jan-05, to lugnet.robotics)
