settings
553-4011-110 Standard 1.0 November 1994
The MVME332XT eight-channel asynchronous board connects the NAC
module with all external devices via the NT6D51AA transition card,
interconnect and external cables. Each MVME332XT eight-channel
asynchronous board can communicate with a maximum of eight devices.
Five different NAC 2 configurations exist for the MVME332XT board:
NAC module with one MVME332XT board (8 ports)
NAC module with two MVME332XT boards (16 ports)
NAC module with three MVME332XT boards (24 ports)
NAC module with four MVME332XT boards (32 ports)
NAC module with five MVME332XT boards (40 ports)
Each board in a NAC module has two banks of switches: a bank of eight
and a bank of four. The set of eight switches has a unique setting for each
card.. Table 3-2 shows the settings for this bank of switches.
For the bank of four switches, the settings on all cards are the same: 1 and 2
are off, and 3 and 4 are on.
Refer to Figure 3-5 for the switch set locations on the MVME332XT board.
