There are 4 LEDs in the center of the front panel and 4 LEDs near the bottom edge.
|100 Mbps||When lit, this green LED indicates a 100 Mbps Ethernet connection has been established.|
|Duplex||When lit this green LED indicates a full duplex Ethernet connection has been established.|
|Link/Active||This green LED is on when a valid Ethernet connection has been established. It blinks when data is being transmitted or received.|
|Status||A green LED blinks approximately twice a second to indicate that the on-board software is running. If the on-board software is not running, a orange LED is lit.|
|TD||There are two green Transmit Data (TD) LEDs, one for each channel. When lit, they indicate bits are being transmitted on the corresponding channel.|
|RD||There are two orange Receive Data (RD) LEDs, one for each channel. When lit, they indicate bits are being received on the corresponding channel.|
Note: It is common in bit-synchronous operation to transmit "flags" on the line continuously whenever it is idle. In this case, the TD LED will flicker as soon as the corresponding channel is enabled.
The bottom of the PXS contains 2 high density DB-26 female connectors. The left connector is synchronous channel 0, the right one is synchronous channel 1. These connectors support RS232 (EIA232), V.35 and EIA530 signaling as defined in Table A.1 and X.21 as defined in Table A.2.
The top of the PXS has three connectors:
10/100 Ethernet: Supports 10 or 100 Mbps. 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.
ASYNC: This is a standard 9 pin asynchronous male connector with full modem control support for RS232. It is used mainly as a console port to configure the PXS. A null-modem cable is supplied to connect to a PC running a terminal emulator. See Table A.3 for cable details.
+5VDC: Connector for the AC adaptor.
Note: The PXS does not have a power switch. Unplug the AC power supply to powercycle it.
