Pos­si­bi­li­ties
The CAN-Bus Tes­ter 2 is a wide­ly used mea­su­ring device for con­trol of bus para­me­ters. The suc­cess sto­ry starts alre­ady in year 2002 with the first model. The hard­ware was com­ple­te­ly rede­si­gned in ver­si­on 2. The cor­re­spon­ding soft­ware is still deve­lo­ped and has been enhan­ced with exten­si­ve updates.
Check the set­up of the bus befo­re you switch on with the bus wiring test, mea­su­re under run­ning con­di­ti­ons down on the phy­si­cal lay­er and ana­ly­ses data of the nodes with the pro­to­col moni­tor. The long time moni­tor shows scat­te­red errors and cree­ping signal loss.
The trig­ger out­put makes it pos­si­ble to show data of only one node of the bus.
The gre­at box con­tents wit­hin the ser­vice case with big adap­ter set makes it pos­si­ble to use the device out of the box in many envi­ron­ments. You can safe your mea­su­rements and print a sta­tus pro­to­col direct­ly from the soft­ware.

Bus Sys­tems
The mea­su­ring device works in the net­works CAN, CANo­pen, Device­Net and SAE J1939.

The CBT2 can also be used for mea­su­rements in other bus sys­tems based on the CAN stan­dard. The­se inclu­de Iso­bus, NMEA 2000 and Safe­ty­Bus P, but also Ener­gy­bus, CAN­a­e­ro­space and ARINC825. Niche bus sys­tems are Mil­CAN and CANo­pen Lift.

Licence Model
In the basic con­fi­gu­ra­ti­on the CAN-Bus Tes­ter 2 is enab­led for bus sys­tem CAN. You can do all phy­si­cal mea­su­rements wit­hin this sys­tem.
Addi­tio­nal licen­ses are offe­red to the sys­tems CANo­pen, Device­Net and SAE J1939. With them it is much easier to assign the messa­ges to the real nodes.
The optio­nal pro­to­col moni­tor is for logi­cal bus ana­ly­sis in the bus sys­tems CAN (trans­mit /​recei­ve), CANo­pen (recei­ve) and SAE J1939 (recei­ve).
The user soft­ware is free to down­load and use, only for mea­su­rements with the CAN-Bus Tes­ter 2 it has to be unlo­cked.

Con­nec­tions
Power Sup­ply
The device works with 9 – 36 V. Only for the Bus Wiring test min. 24 V are nee­ded.

USB Port
Con­nect your win­dows PC or lap­top here.

CAN and CAN pro­be port
Two 9-pin D-Sub ports are for con­nec­tion to the bus and for pro­bes

Trig­ger Out­put
For fur­t­her mea­su­rements with a digi­tal sto­ra­ge oscil­lo­scope the CAN-Bus Tes­ter 2 can be used as trig­ger source.

Two Devices in one
The CAN-Bus Tes­ter 2 is basi­cal­ly a 2-in-1 device. One part is respon­si­ble for the exten­si­ve mea­su­rements on the phy­si­cal level. 64-fold sam­pling of each indi­vi­du­al bit makes detail­ed eva­lua­ti­on pos­si­ble.
The other part is a CAN-to-USB inter­face for com­pre­hen­si­ve pro­to­col ana­ly­sis. Both parts of the device can work inde­pendent­ly of each other or simul­ta­neous­ly and toge­ther.

Among many other things, it is pos­si­ble to stop the pro­to­col ana­ly­sis auto­ma­ti­cal­ly if the phy­si­cal mea­su­ring device has detec­ted a pro­blem. In this way, the data traf­fic can be eva­lua­ted imme­dia­te­ly befo­re an error occurs. You don’t have to search through long lists of tele­grams, the end of the list is the rele­vant point.

Bus Wiring Test
With the wiring test, it is pos­si­ble to deter­mi­ne line short-cir­cuits, line breaks, the bus ter­mi­na­ti­on, the loop resis­tan­ces of the CAN line and the CAN power sup­ply line, and the over­all line length.
To ensu­re cor­rect bus cabling, it is recom­men­ded to per­form the wiring test at the begin­ning of any plant mea­su­rements.

Node Mea­su­rement
Con­nect the CAN-Bus Tes­ter 2 to your bus line. Your should see a green led on your dis­play, sho­wing that the­re is data traf­fic.
First start the baud rate scan, then scan for nodes. All messa­ges on the bus are now recei­ved and ana­ly­sed, the nodes with their ID are listed. Name the nodes if you want for bet­ter over­view.
With the mea­su­rement “all sta­ti­ons view” you get an over­view of the qua­li­ty levels of the signals. The bar dia­gram makes it ease to com­pa­re. At con­ti­nuous mode you will addi­tio­nal see the min/​max values. You can easi­ly com­pa­re to a saved mea­su­rement.
The mea­su­rement “one sta­ti­ons view” shows the sin­gle values of one node and shows a phy­si­cal and logi­cal deco­ded oscil­lo­gram. Qua­li­ty level, edge steep­ness and dis­tur­ban­ce free vol­ta­ge ran­ge are the three show­ed mea­su­rands. By star­ting a con­ti­nuous mea­su­rement you will also see min/​max of qua­li­ty level and the varia­ti­on of the dis­tur­ban­ce-free vol­ta­ge ran­ge.

Online Moni­tor
This mea­su­rement runs con­ti­nuous­ly and com­pa­res with given thres­holds. If it over­runs the thres­hold the error will be regis­te­red. At sin­gle mea­su­rement mode it stops and the faul­ty messa­ge is show­ed in the oscil­lo­scope view. In con­ti­nuous mode the error is mar­ked in a time dia­gram. So you show when your thres­hold was overrun’ed or if a error­frame has occur­red.

The obser­ved values are
Active-Error /​Pas­si­ve-Error Frames
Over­load Frames
Ack­now­ledge Error
Gene­ral qua­li­ty level (0 … 100 %)
Dis­tur­ban­ce-free vol­ta­ge ran­ge (mini­mum noise free dif­fe­ren­ti­al vol­ta­ge)
Edge steep­ness (worst rising and fal­ling edge of a messa­ge)

Addi­tio­nal­ly to this logi­cal and phy­si­cal mea­su­rements the CAN-Bus Tes­ter 2 is con­ti­nuous­ly deter­mi­ning bus traf­fic load, bus sta­tus and the optio­nal CAN sup­ply vol­ta­ge.
The soft­ware can be adjus­ted in a way, that a simul­ta­neous­ly run­ning Recei­ve in the pro­to­col moni­tor is stop­ped in case of an error. So it is easier to ana­ly­se that data traf­fic that was on the bus befo­re the error occurred.

Pro­to­col Moni­tor
Many fea­tures of the CAN­vi­si­on Pro­to­col Moni­tor are build in the CAN-Bus Tes­ter 2 user soft­ware. It is easi­ly unlo­cked when you buy a licen­se.
Inform yours­elf about the ran­ge of fea­tures of CAN­vi­son here.
Main dif­fe­rence is the net­work capa­bi­li­ty, this can only be used with the full ver­si­on of CAN­vi­si­on.
