Quad SIO PCA (A6 and B6) options - part number: NT6M60BA
Device Position/setting
type
Note 5: This PCA supports polling on digital data lines or on analog network. For digital data lines
check that:
a. the P/A Comm PCA at A16 is part number NT6M84BA
b. the Four Channel COMM PCA at A17 is release 03 or later
c. the HOC supports the digital data line feature.
Note 6: The internal transmit timing source is generated on the Quad SIO PCA. The external
transmit timing source is brought in from a source outside the BMC, usually associated with a
modem generated timing source from a digital data line.
Note 7: Factory settings shown are for digital data line (external timing).
Note 8: Verify that the settings on the jumpers J2-J13 on the Quad SIO PCA are in agreement with
the settings on the P/A Comm PCA (A16) when working with digital data lines.
Note 9: There are no customer-definable options on this PCA. Information is shown for reference
only. This data is to be used for verification during initial BMC system installation and/or PCA
replacement to ensure that the replacement PCA is set-up in the same fashion as the PCA being
replaced.
