This section provides a functional description of the PRV-1059. Functional Description PRV-1059 is a rugged VLAN-capable 5-port PC/104 Fast Ethernet switch featuring very low power consumption and highly reliable extended-temperature operation up to +85°C (185°F). Supporting auto-MDI-MDIX network installation, the board is designed for simple plug-and-play operation, enabling up to five embedded computing devices to be networked together using 10BaseT or 100BaseTX Local Area Network (LAN) connections.

2-pin power header, depending on the version purchased. The VLAN-enabled switch requires use of the Parvus cable (sold separately) and software to configure the VLAN settings. Configuration and connection of the VLAN switch is described in chapter 5.

This chapter explains the operation of the switch. Switch Data Flow The switching portion of the PRV-1059 receives good packets from the MAC’s, processes them, and forwards them to the appropriate MACs for transmission. Processing the frames is the key activity, and involves the Ingress Policy, the Queue Controller, the Output Queues, and the Egress Policy blocks shown below.
PRV-1059 User Manual Half- and Full-Duplex Flow Control Half- and Full-duplex flow control is used to throttle the end station to avoid dropping packets during network congestion. When the free buffer space is almost empty or the output queue is almost full, the MACs force a collision in the input port when sensing an incoming packet.
The following diagrams are similar to those which can be seen within the Parvus VLAN software and are included to illustrate the concept of VLAN on the PRV-1059. Figure 1 below shows a switch and all five ports with no restrictions; any port can talk to any other port. This is the state of non-VLAN switches and is also the factory default setting for the VLAN-enabled switch.

PRV-1059 User Manual Figure 1) Non-VLAN configured state. Unlike Figure 1 above, a VLAN configured switch limits which ports can communicate with each other. The following diagram is a sample of the way that the switch may be setup. Figure 2) Known VLAN configuration Figure 2 is VLAN configuration where Ports 0, 1, and 2 form a VLAN.
PRV-1059 User Manual VLAN Software Quick Start Setup Guide In order to change the VLAN configuration on the PRV-1059 5-port Switch, Parvus has provided the user with a simple-to-use GUI program. Implementation of the program is through an RS-232 serial cable connection between a COM port on the host computer and the serial port on the switch.
Com Port In order to program the PRV-1059, the computer running the software must be connected to the serial port of the switch. The default COM port for the host computer is set to COM 1. If the user uses a different COM port, the COM port setting can be changed by selecting the COMM menu located at the top left of the GUI window.
Each port can only send data to its egress port. In this example, each port has only one egress port, but on the PRV-1059 it is possible for each to have between zero and four egress ports. There are 5 egress port configuration schemes ranging from “Set Egress Ports for Port 0” to “Set Egress Ports for Port 4”...
VLAN commands will be implemented by these buttons. a) Apply– causes the “New VLAN Configuration” to be written to the registers of the PRV-1059 allowing the user to test the VLAN settings. Note that as soon as the switch is powered off, the MNL-0490-01 RevD4 REF.
COMM– allows user to select a COM Port on the host computer. c) Program– writes the current VLAN settings to an EEPROM on the PRV-1059. Note that every time when you re-configure the switch using the apply button, the new VLANs are only valid until power is lost.
Non-Operating: -55ºC to +100ºC Reliability (MTBF) The following table shows the predicted values for reliability of the PRV-1059] as a Mean Time Between Failures (MTBF) 1.503 Million Hours @ 40°C (Per MIL-HDBK-217F, Ground Benign, Controlled GB, GC) 157,971 Hours @ 40°C (Per MIL-HDBK-217F, Airborne Inhabit Fighter, AIF) 60,164 Hours @ 40°C (Per MIL-HDBK-217F, Airborne Rotary Winged, ARW)
PRV-1059 User Manual Dimensions 3.550” x 3.775” RJ-45 Version Warning: PC/104 specifications state that max height may only be 0.435”. Be sure that the board height of 0.52” for the RJ-45 version will operate in your application. This applies to the RJ-45 version only.
