Chapter 5 Serial Mobile Interface Card
2-port SMIC Rotary Switch Positions
Table 5-4 shows the 2-port SMIC serial signal assignments. The position of the rotary switch determines
the port assignments. Although the rotary switch has 8 positions, only 1 of 2 positions can be selected.
The rotary switch position should be unique for each mobile interface card (MIC) card.
SMIC LED Signals
Table 5-5
shows the LED signals that are supported on the SMIC, along with the corresponding
functions. Serial 2 and Serial 3 apply to the 4-port SMIC only.

SMIC LED Functions
LED
Function
SERIAL0 ACTIVITY
Blinks once when a packet is either transmitted from or received on Serial 0.
Originates from Header 5.
SERIAL0 LINK
Indicates the status of Serial 0. Originates from Header 5. The LED is on
when a serial port is in DTE mode, and when the data set ready (DSR), data
carrier detect (DCD), and clear to send (CTS) signals are detected. The LED
is on when a serial port is in DCE mode, and when the data terminal ready
(DTR) and request to send (RTS) signals are detected.
SERIAL1 ACTIVITY
Blinks once when a packet is either transmitted from or received on Serial 1.
Originates from Header 5.
SERIAL1 LINK
Indicates the status of Serial 1. Originates from Header 5. The LED is on
when the serial port is in DTE mode, and when the DSR, DCD, and CTS
signals are detected. The LED is on when the serial port is in DCE mode, and
when the DTR and RTS signals have been detected.
SERIAL2 ACTIVITY
Blinks once when a packet is either transmitted from or received on Serial 2.
Originates from Header 2.
SERIAL2 LINK
Indicates the status of Serial 2. Originates from Header 2. The LED is on
when the serial port is in DTE mode, and when the DSR, DCD, and CTS
signals are detected. The LED is on when the serial port is in DCE mode, and
when the DTR and RTS signals have been detected.
SERIAL3 ACTIVITY
Blinks once when a packet is either transmitted FROM or received on
Serial 3. Originates from Header 2.
SERIAL3 LINK
Indicates the status of Serial 3. originates from Header 2. The LED is on
when the serial port is in DTE mode, and when the DSR, DCD, and CTS
signals are detected. The LED is on when the serial port is in DCE mode, and
when the DTR and RTS signals have been detected.
