Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of Signals Transfer Board, plurality of level signal conversion module and corresponding physical interface is integrated on the same vector
Signals Transfer Board is constituted, Signals Transfer Board further includes a power connector, for the multiple level signal conversion module
Power supply；Data are sent mutually by AccessPort software and Signals Transfer Board on computers, if the data of transmitting-receiving are identical just to be proved
Plurality of level channel it is unobstructed, on the other hand, what it is if necessary to test is that ethernet signal switchs to other kinds of level letter
Number channel, at this time needs for the ethernet signal output port of channel to be connected with the physical port of computer, and by the channel
Corresponding other types level signal another port is connected with USB conversion module, and USB conversion module is connected with the USB port of computer,
Using AccessPort software and Networked E-Journals software, so that computer is mutually sent out data with Signals Transfer Board just can test whether the channel leads to
Freely.
Plurality of level signal conversion module (includingConversion chip,Conversion chip,Conversion chip andConversion chip) it is related to Etc. different types level signal conversion.
Different types of level signal has different advantage and disadvantage.These three level standard (various standard rule of RS232, RS422, RS485
Determine in electrical characteristic (for example how many volts are logical one) and interface mechanical property (shape, stitch definition) of port etc.
Hold.) physical interface can use DB9 aciculiform formula serial communication interface.The physical interface of RS232 level signal uses one
Root signal wire and a signal line of return and the transmission form for constituting total ground, this transmit altogether be easy to produce common mode interference.
RS232 only allows One-to-one communication, and transmission range is about in more than ten meters.Point-to-point communication party may be implemented in RS232 interface
Formula, but this mode can not achieve network savvy.RS232 transmission rate is lower, in asynchronous transmission, baud rate 20Kbps.
RS422 has 4 signal wires, and two transmissions, two piece-root graftings are received.The receipts of RS422 are to separate with hair, it is possible to while receiving and sending out
(full duplex).Full duplex requires transmitting-receiving to have individual channel, so RS422 is suitable for communicating between two stations, Star network, ring
Net is not useable for bus network.RS485 only has 2 signal wires to be usually used in bus network so can only operate in semiduplex mode.
RS485 interface is the combination using balance driver and differential receiver, and noise immunity is good, and transmission range is up to thousands of
Rice.RS485 interface is to allow to connect up to 128 transceivers in bus, and it is convenient that user can use single RS485 interface
Set up device network in ground.The data maximum transmission rate of RS485 is 10Mbps.General TTL (transistor-transistor logic electricity
It is flat, Transistor-Transistor Logic) for signal system using Transistor-Transistor Logic level standard, this is computer processor control
The standard technique communicated between each section inside the equipment of system.The TTL signal of computer-internal need with can be with when PERCOM peripheral communication
Turn USB module by TTL or TTL turns ethernet module, carries out related data transmission.(Ethernet is abbreviated as Ethernet
It Eth), is the widest local area network technology of current application, its message transmission rate range of different types of ethernet technology standard
By 10Mbps to 100Gbps etc., several meters to tens kilometers of transmission range range are differed.
By various level signal standard handovers modules and corresponding physical interface, (such as DB9 physics connects USB conversion module
Mouthful etc.) composition, and in particular toModule,Module,Module,Module
Deng, effect be that various level standard signals are switched to usb signal to communicate with test equipment (usually computer), use string
Mouth debugging software mutually sends out data and carries out the unobstructed of test channel.
Debugging software refers mainly to AccessPort software, Networked E-Journals software.Physical interface can be DB9 needle serial port, aviation
Socket, network socket, industrial-controlled general line socket, powerlink socket etc..
The power connector uses J30J-4ZJWP7 power connector.
The physical interface includes J30J-51TJW-J connector, J30J-37TJW-J connector, J30J-21TJW-J company
Connect device, J30J-21ZKW-J connector, J30J-15TJW-J connector, J30J-9TJW-J connector, J30J-9ZKW-J connection
