CEI-220 Interrupts and Slew Rate
The CEI-220 interrupts are software-controlled. See the “Hardware
Interrupt Control” section for information on selecting interrupts.
The CEI-220 slew rate is controlled automatically as a function of the
selected bit rate.
CEI-220 ARINC Connector Pin Out
To couple the CEI-220 to ARINC devices, two, 37-pin Subminiature “D”
type connectors are provided. The connector pin numbers are listed in
Figure 11. The end-panel connector (P3) is female, and the rear connector
(P4) is male.
To make an external wrap adapter, use a DB37 male connector and tie pin
1 to 20, 2 to 21, etc. through 18 to 37.
