The front panel of the PXSe has two connectors:
+5VDC: Connector for the AC adaptor.10/100 Mbps: Supports 10 or 100 Mbps Etnernet. The port will
autodetect the signals received, so you can use a straight cable to connect
either to a hub, switch or directly to a NIC in a PC.
There are 9 LEDs in the front panel:
| LED | Description |
|---|---|
| FDX | When lit, this green LED indicates a full duplex Ethernet connection has been established. |
| 100 | When lit, this green LED indicates a 100 Mbps Ethernet connection has been established. |
| ACT | This green LED is on when a valid Ethernet connection has been established. It blinks when data is being transmitted or received. |
| RD0 | When lit, this green LED indicates data is being received on synchronous channel 0. |
| TD0 | When lit this green LED indicates data is being transmitted on synchronous channel 0. |
| SG1 and SG2 | These two green LEDs are normally off. If a daughter card is installed, SG1 shows when data is being received from the daughter card and SG2 shows when data is being transmitted to the daughter card. |
| ST1 | When this red LED is lit continuously, RedBoot is running and waiting for input. When this led is flashing, it indicates the application is in a failed state. |
| ST2 | This green LED blinks approximately twice a second to indicate that the on-board software (either RedBoot or an application) is running. |
Note: It is common in bit-synchronous operation to transmit "flags" continuously whenever the line is idle. In this case, the TD0 LED will flicker as soon as the corresponding channel is enabled.
The rear panel of the PXSe has a 24-pin Hirosi connector labeled
SYNC/ASYNC. By default, this is synchronous channel 0. This
connector supports RS232 (EIA232), V.35 and EIA530 signaling as
defined in Table A.4 and X.21 as defined in
Table A.5.
Under software control, this connector can be attached to the PXS asynchronous port, for applications that requiere asynchronous communications. The pin assigments are the same shown in Table A.4, except for the clock signals (that do not exist in asyncrhronous communications).
Note: The PXSe does not have a power switch. Unplug the AC power supply to powercycle it.
