JP2 - VME
JP2 is a group of four jumpers that set the VME bus address of the board. The
Address
address should reflect the board location in a D200 CCU chassis.
Example: The board with address 1 will be the lead node, with nodes 2 through 8
Note:
JP3-1 and
These two jumpers determine the Real Time Clock (RTC) source for each D20ME
JP3-2
board in a CCU.
RTC Options

Single-node D20s and the first, or Lead, node of a D200 will use their internal
clock.
•
Non-lead nodes of a D200 must synchronize their clocks to node 1's clock.
