DIP Switches
Two 4-position switches (SW1 & SW2) allow for configuration of the D to A channel, DAR density, and
module outputs for the 4100-0622, -1341 Digital Audio Riser Module. See Table 9.
Table 9. Switch Positions for the 4100-0622, -1341 Digital Audio Riser Module
CAUTION:
1. All four positions of Switch 1 are set to OFF at the factory to avoid module output
damage. Positions 3 & 4 are only ON for Digital Systems. For Analog Systems,
Positions 3 & 4 MUST REMAIN OFF to avoid DAR damage.
2. If the 4100-0622 DAR Module is installed in a bay where PDI Channel 2 is driven
by a 4100-1210 Analog Audio Controller or a 4100-1265 Degraded Fail-Safe
Mode Microphone Preamp, Switch Positions 1 & 2 MUST BE OFF to avoid
damaging the NAA output.
