Programming the Power Manager Device
The J12 header can be used to isolate and program the ispPAC-POWR1220AT8 Power Manager device. This
device can be isolated from the others on the chain using the optional ispEN connection from the ispVM program-
ming cable. Connecting ispEN to pin 5 on J12 and selecting the optional control in ispVM will isolate the Power
Manager. The connection is activated from the

pull-down menu of the ispVM toolbar. The Cable and I/O
Port Setup dialog box is used to select the polarity of this connection to SET LOW.
