REC
Table 3.2
The remote diode on board the EMC2104/05 EVB has a heater and an optional inline series resistance
adjustment. Checking the REC feature of the EMC2104/05 is accomplished by removing the jumper
on JP9. This adds 100 ohms of series resistance to the DN line of the diode connection. To return to
0 ohm series resistance, replace the jumper on JP9.
To heat the diode, place a jumper on JP10 in position 1-2. To return to ambient conditions, place
shorting bar in position 2-3 on JP2. These remote diode options are summarized in
