Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36' cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port.Realterm can connect to both SERIAL ports (real uarts, as well as USB, and network virtual uarts) or TCP/Telnet ports. It allows you to control RS-232 devices right from your PC - with various combinations of COM port settings (Port, Baud rate, Data bit, Parity, Stop bit, and Flow control), and theIPNetSim™ is an optional application available within PacketExpert™ platforms (PXG100 and PXN100).USB to TTL Serial Cable - Debug / Console Cable for Raspberry Pi (Adafruit 954) The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Serial port terminal is another important feature available in the 232Analyzer software. The unit is powered from the USB port and it supports data auto-sensing & self-adjusting, which automatically adjust baud rate, parity, stop bit. This high-quality, high-performance, port-powered, bi-directional USB to TTL converter can be used to convert any standard full-duplex USB port into a full-duplex 5V TTL port and vice versa. Equipment manufacturers, network engineers, application developers and service providers can safely and reversibly introduce these impairments and study the subsequent behavior of the network or application.Details.MTOP™ solution (MT001), is a 1U rack mount enclosure within which PacketExpert™ 10GX (PXN100) USB units can be stacked to provide high density GigE ports form factor solution for testing GigE switches, routers and network conditions. These user defined streams can be modified to simulate network impairments.IPLinkSim™ option with PacketExpert™ platforms (PXG100 and PXN100) also supports a single stream WAN IP Link with a 10 Gbps or a 10/100/1000 Mbps full duplex link, where all the incoming traffic is streamed as a single link which can be modified to simulate network impairments.Both IPNetSim™ and IPLinkSim™ applications are available as rackmount appliance with PXN100 and mTOP™ (MT001). For each direction, incoming traffic can be identified into separate user defined streams (up to 16 streams for 1 Gbps pipe and up to 4 streams for 10 Gbps pipe).IPNetSim™ operates in multi-stream mode. In addition to the above listed impairment types, IPLinkSim™ can also emulate congestion in the network by generating additional background traffic.Both IPNetSim™ and IPLinkSim™ supports Command line Interface (CLI) to access all the functionalities remotely using TCL clients and MAPS™ CLI client/server architecture. Or increase packet latency to simulate long network paths. For example use bandwidth throttling to simulate a slow WAN link like RS232/DSL/Modem/T1/E1/T3/E3 etc.Emulate WAN conditions separately and independently on each direction. Scalable solution for unlimited number of ports Stack multiple rack units to handle large number of ports. mTOP™ offer rack-mountable, high density, multi-device support. IPLinkSim™ operates in a single stream mode and emulates only 1 bidirectional WAN Link per unit
![]() Usb To Ttl Emulator Software Serial Console PortFor each stream definition, offset can be set to any byte within the packet (from 0 to 2047) which gives flexibility to define any fields within any protocol headers, and even the payload Up to 120 bytes wide stream definitions covering entire packet header from MAC to UDP and also Payload Supports both Raw (bit level) and Packet mode (header fields) stream configurations classifies traffic on each port into separate streams (up to 16 streams on 1 Gbps ports and 4 streams on 10 Gbps ports) Streams can be defined with various header fields like Source/Destination MAC Address, VLAN Id, MPLS Label, Source/Destination Ipv4 Address, Source/Destination UDP ports ”Stream Definition” feature in IPNetSim™ Bandwidth control option to emulate various WAN link speeds (Modem, DSL, T1/E1/T3/E3/OC3/OC12 etc) – 1 Kbps up to 10 Gbps Check the stability or performance of the network with various real-world WAN Impairments including: Live throughput graphs per stream to visualize the effects of WAN impairments on the traffic Detailed per stream Tx Rx frames statistics for easy performance monitoring ![]() IP Source and Destination Address Range Hardware wire-speed filters (up to 16 links) Command Line Interface for automated testing and remote accessibilitySoftware Specification Multi-streams WAN Emulation - IPNetSim™ Supports transmission of Ethernet Pause frame with user-defined quanta used to throttle Ethernet link overload Supports both periodic and random impairments such as packet loss, packet reordering, packet duplication, and error insertion Logic Error Insertion Rate - 10 -1 to 10 -9 single delay, uniform, random distributions 0 milliseconds up to 0.5 seconds (500 msec) per stream (for 10 Gbps link) 0 milliseconds up to 1.25 seconds (1250 msec) per stream (for 1Gbps link) Congestion Emulation with Background traffic (% of total bandwidth) 0 milliseconds to 8 seconds (8000 milliseconds) (for 1G/10 Gbps link) Bandwidth control - 10 Kbps up to 1000 Mbps By default, P1 and P2 work in pass-through mode, and pass all frames across to the other port. The bandwidth can be controlled to simulate various WAN link speeds (RS232/DSL/Modem/T1/E1/T3/E3 etc.).P1 -> P2 is one link and in the reverse direction, i.e., P2 -> P1 forms the other link. The links are emulated between Port 1 (P1) and Port 2 (P2). It can be configured to act either as a transparent bidirectional Ethernet link or a simple Ethernet bridge between 2 end points. FCS Error insertion Rate - 10 -1 to 10 -9PacketExpert™ is connected to the 2 end points of a WAN link. Free mac cleaner softawareWhen WAN Emulation is started by the user, the impairments are introduced into the traffic as shown below.Impairing Multi-streams over P1->P2 and P2->P1 LinkIn single stream mode (IPLinkSim™), all the incoming traffic is streamed as a single link, which can be impaired with various link conditions such as Bandwidth Control, Background Traffic, Latency, Packet Loss, Packet Reordering, Packet Duplication, Error Insertion emulating real-world scenarios.Impairing Single stream over P1 -> P2 and P2 -> P1 LinkPacket Loss can be introduced either as a rate as well as Manually. WAN impairments can be configured independently for each stream. Bidirectional streams can be configured as a symmetrical (identical WAN impairments in both directions) or asymmetrical (different WAN impairments in each direction). These settings can be applied for the selected 16 unique streams on 1Gbps link and 4 unique streams on 10Gbps link independently in each direction.Traffic (bidirectional streams) can be processed at wirespeed (1Gbps or 10Gbps). For each stream, a different set of WAN Emulation parameters can be applied, a single IPNetSim™ can emulate different WAN scenarios like Head Office to Data Center, Head Office to Branch Office etc.IPNetSim™ on PXN100 (Multi-Stream/Single Stream WAN Emulator) connecting 2 network end pointsWAN Emulation includes various real-world impairments such as Bandwidth, Latency, Packet-Loss, Error Insertion, Reordering, and Duplication, to check the performance of end equipment to real world impairments. Manual Drop: This allows user to manually drop either a single packet or burst of packets at run time. For both periodic as well as random packet loss, the overall packet loss rate is maintained, but only the way the packets selected for dropping is changed User can choose a periodic loss, where the packet drops will be regular and predictable, or random packet loss, where packets will be dropped randomly. Rate: User can configure the Loss rate, and packets will be dropped at that rate.
