Dual-Port Serial PIM
The Dual-Port Serial PIM (Figure 28 on page 47) provides a physical connection to
serial network media types through two serial interface ports.
Figure 28: Dual-Port Serial PIM
The Dual-Port Serial PIM provides the following key features:
■ Onboard network processor
■ Autoselection of operation modes based on data terminal equipment (DTE) or
data communication equipment (DCE) cables
■ Local and remote loopback diagnostics
■ Configurable clock rate for the transmit (Tx) clock and receive (Rx) clock
For pinouts of cable connectors for serial PIMs, see “Serial PIM Cable
Specifications” on page 179.
To install or remove a PIM, see “Replacing a PIM” on page 120.
Status LEDs indicate port status. Table 25 on page 48 describes the meaning of the
LED states.
