Requesting Cold Start Information

When the DXP-T1 system is turned on, internal self-tests are run to determine the condition of the
system. When you use this request, you are asking the system to provide you with the results of these
tests. Upon making the cold start information request, the system verifies the following.
•
operating mode is superframe (SF) or extended superframe (ESF),
•
FDL daughterboard (used for ESF) is installed on the T1 board and okay or not installed (or defective),
•
channel capacity currently selected is 8, 16, or 24 channels,
•
static RAM is okay or has read/write errors,
•
internal CPU RAM is okay or has read/write errors.
4.2.1 Setting The DIP Switches For Cold Start Information
Set the DIP switches as shown in the following table. Switch 1 is the top switch. When the switch is
moved to the right, it is turned on. The hex code shown is used for remote operation only.
