1.3 Switch S1 and S2 Configuration

16 PCIE-5565PIORC Reflective Memory Board
Prior to installing the RFM‐5565 in a host system, the desired node ID must be set
using switch S2. Each node in the network must have a unique node ID. See
Figure 1‐1 on page 18 for the location of switch S2.
Switch S2 corresponds to 8 node ID select signal lines. The 8 node ID select lines
permit any binary node ID from 0 to $FF (255 decimal). Switch S2 position 1
corresponds to the least significant node ID line and switch S2 position 8
corresponds to the most significant node ID line. Placing switch S2 in the OFF
position sets the binary node ID line low (0), while placing switch S2 in the ON
position sets the binary node ID line high (1). Table 1‐1 on page 17 provides
examples of possible node IDs.

1.3.1 Before Installation Switch S1 and S2 Configuration

NOTE
ALL nodes on the ring MUST be configured for the SAME transfer mode, either redundant or non-
redundant transfer mode. A mismatch of this setting will result in certain packets being removed
from the ring, and that data will be lost.
NOTE
No more than one node on the ring should be configured with Rogue Master 0 enabled. Certain
packets will be removed from the ring when two or more nodes are configured with Rogue
Master 0 enabled, and that data will be lost.
NOTE
No more than one node on the ring should be configured with Rogue Master 1 enabled. Certain
packets will be removed from the ring when two or more nodes are configured with Rogue
Master 1 enabled, and that data will be lost.
Prior to installing the RFM‐5565 in the host system, switch S1 must be configured
for the appropriate mode of operation. Switch S1 controls six functions on the
board. Settings on Switch S1 should only be changed while power is off.
1. S1 position 1 selects the non‐redundant (OFF position) or redundant net‐
work transfer modes.
2. S1 position 2 selects between the low network usage (ON position) of the
classic 5565 boards or the higher performance achievable on this board (OFF
position).
3. S1 positions 3 and 4 select the PCI window size for PIO memory accesses.
The default (when both switch positions 3 and 4 are OFF) is to use the full
installed memory size. The reduced memory window size choices are
64 MByte, 16 MByte or 2 MByte.
4. S1 position 5 enables (ON position) or disables the Rogue Master 0 function.
5. S1 position 6 enables (ON position) or disables the Rogue Master 1 function.
6. S1 position 8 selects between the factory default control logic (ON position)
or the most recent control logic flashed to the board (OFF position).
S1 position 7 is currently reserved and should not be used (left in the OFF
position).
