JP1 - VME
Control
This jumper sets the Master or Slave role of the board on the VME bus.
Note:
Single-node (D20) systems are always set to Master
JP2 - VME
Address
JP2 is a group of four jumpers that set the VME bus address of the board. The
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
positioned to the right of the lead node.
Note:
Single-node D20s are set to address 0 (all jumpers IN)
JP3-1 and
JP3-2
RTC Options
These two jumpers determine the Real Time Clock (RTC) source for each D20ME
board in a CCU.
• 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.
