[Emc-users] Mesa 7I33 Aux Power

2008-04-02 Thread Eric H. Johnson
Hi all, I am getting a large voltage drop when I connect the analog outputs from the 7I33 to the load. With no load they show the correct voltages. The Mesa manual states Due to power supply limitations, The 7I33 has limited DC output drive capability and should not have loads of less than 5K

Peter, I think that agrees with what I am seeing. I measured the load and in fact it is 20K ohm. I also tried an AUX 5 V supply, and as John said, it made almost no difference (went up by about 1/2 mA). The 5V looks to be good, there is other general I/O which all are working fine. I also
