The reflective memory cards are accessed through the A32 address space of the VMEbus, appearing at addresses from 0 to 0xa00000. Any card installed in an antenna computer crate should be given address 0. Cards installed in the central computer crate are addressed according to which antenna is on the other end of the link. These addresses are configured on pins A20-A23 (the middle four pins on J7) as shown in the table. Also, each card must have a node ID set on pins ID0-ID3 (looking at the component side of the board with the VMEbus connectors to the right, the rightmost four pins in J9).

Jumpers should be installed in all remaining positions (A24-A31 in J4, AP18-AP19 and A18-A19 in J7, and ID4-ID7 in J9).
