PACS1284
Application Information (continued)
Table 2 provides the IEEE 1284 signal assignments for
the three connectors, and example PACS1284 pin con-
nections.
When connecting a 1284-A host to a 1284-B periph-
eral, the “Peripheral Logic High” signal is not used.
Similarly, when a 1284-A host is connected to a 1284-
C peripheral, the “Peripheral Logic High” and “Host
Logic High” are not used. These two signals are
optionally used to detect a “Power Off” or “Cable Dis-
connect” state for host and peripheral, respectively.
