Supply DC power directly to the power supply jack. DC power supplied
must be +5VDC ±5%, 500mA minimum, center positive, and can be sup-
plied via a barrel type plug with 2.1/5.5/10mm I.D./O.D./Shaft Length
dimensions. For this powering option, set J3 to position 7 and 8 as
shown in figure 4 (factory default).
The 36-60 VDC DC to DC adapter is supplied with the DC version of the
Model 2124/2130. The black and red leads plug into a DC source (nom-
inal 48VDC) and the barrel power connector plugs into the barrel power
supply jack on the 2124/2130. See Figure 5 below. For this powering
option, set J3 to position 7 and 8 as shown in figure 4 (factory default).
DC power (+5VDC) can also be supplied via pins 21 or 25 on the DB-25
connector for the Model 2124. DC power (+5VDC) can also be supplied
via pins 21 or 25 on the DB-25 connector for the Model 2130.
