{Indicator|Sign|Indication} light {method|technique|approach}:


CPU {indicator|sign|indication} light


The CPU {indicator|sign|indication} lights is {flashing|blinking} when it {works|functions} {normally|typically|usually|generally}. If {keeps|maintains} {lighting|illumination|lights} {or not|or otherwise} {bright|brilliant|intense}, there's the {possibility|opportunity} that the CPU is {connected with|gotten in touch with} the {wrong|incorrect} power supply, or the controller chip {has|has actually} been {damaged|harmed}


CARD {indicator|sign|indication} light:


As long as {punching|boxing} in {any|any type of|any kind of} card {reader|visitor|viewers} under the controller {and|as well as|and also} {pass through|go through|travel through} the card number, the {indicator|sign|indication} light flashes. If the {indicator|sign|indication} light {doesn't|does not} {respond|react} after punching, the {problems|issues|troubles} {may|might} be:


The circuit from the card {reader|visitor|viewers} to the controller is {broken|damaged}, or the {data|information} {wire|cable|cord} is {connected|linked|attached} {wrong|incorrect} or {connected|linked} reversely


The {output|outcome|result} {format|style|layout} of the card {reader|visitor|viewers} is {incorrect|inaccurate|wrong}


The card {reader|visitor|viewers} is {broken|damaged}


The card {reader|visitor|viewers}'s input port of the controller is {broken|damaged}


ERR {fault|mistake} {indicator|sign|indication} light:


The light is not {bright|brilliant|intense} under {normal|typical|regular} {condition|problem}. If the light flashes or {keeps|maintains} {lighting|illumination|lights}, the {problems|issues|troubles} {may|might} be:


The {chips in|contribute} the controller {probably|most likely|possibly} {burn out|stress out|wear out}, {storage|storage space} {disorder|condition|problem} {needs|requires} to {format|style|layout}, or {other|various other} {faults|mistakes}. Please {contact|get in touch with|call|speak to} the {manufacturer|producer|maker|supplier}'s {technician|specialist|service technician|professional}


{Communication|Interaction} {indicator|sign|indication} light:


485 controller


Rx light {indicates|suggests|shows} the controller {receives|gets|obtains} signals ({including|consisting of} {normal|typical|regular} {and|as well as|and also} {interference|disturbance} signals)


Tx light {indicates|suggests|shows} the controller {emits|produces|gives off|releases|discharges|sends out} signals


TCP controller:


Rx ({Link|Web link}) light, {keep|maintain} {always|constantly} lighting {indicates|suggests|shows} there are {no problems|not a problem|no worry} with {wires|cables|cords} {connecting|linking|attaching}. (It is {also|likewise|additionally} {possible|feasible} that there are some {special|unique} {problems|issues|troubles} that {have|have actually} not been {detected|spotted|discovered|found|identified} {and|as well as|and also} can {only|just} be {said|stated|claimed} to be {basically|essentially|generally|primarily} {normal|typical|regular}.)


Tx light, {flashing|blinking} {indicates|suggests|shows} being {communicating|interacting|connecting}


{Substitution|Alternative|Replacement} {method|technique|approach}:


{Equipment|Devices|Tools} {substitution|alternative|replacement} {method|technique|approach}:


{Replace|Change} the {faulty|defective|malfunctioning|damaged} {equipment|devices|tools} with {a device|a gadget|a tool} that {is sure of|ensures} {good|great|excellent} ({usually|typically|normally|generally} {tested|evaluated|checked|examined}, {often|frequently|typically|commonly|usually} {used|utilized|made use of}) to see if the {malfunction|breakdown} is gone


If it {goes away|disappears|vanishes}, it's {possible|feasible} that the {device|gadget|tool} is {broken|damaged}. {But|However|Yet} it's not {entirely|completely|totally} {certain|specific|particular}, {because|since|due to the fact that} if it's {an environment|an atmosphere|a setting} or something that {causes|triggers|creates} {a failure|a failing}, it {doesn't|does not} {necessarily|always} {show up|appear|turn up} {right away|immediately|right now|as soon as possible|today}, or it's {going to|mosting likely to} {hurt|harm|injure} the {new|brand-new} {device|gadget|tool} {for a while|for some time}


If the {device|gadget|tool} {in question|concerned}, {separate|different} {test|examination} {no problem|not a problem|no worry}, this {may|might} be {related to|associated with|connected to} {environmental|ecological} {problems|issues|troubles} such as {wiring|electrical wiring|circuitry}. One {should|ought to|must|need to} {actively|proactively} {continue to|remain to} {find out|discover|learn|figure out} the {fault|mistake} {source|resource}. Do not {think|believe|assume} that {change|alter|transform} the {equipment|devices|tools} {means|implies|indicates|suggests} {everything|whatever|every little thing} is all right


{Notebook|Note pad} {substitution|alternative|replacement} {method|technique|approach}


Can {check out|have a look at|take a look at|look into} if there are {problems|issues|troubles} with the {user|individual|customer}'s {computer|computer system} or {operating|running} system or with the {wrong|incorrect} {setup|configuration|arrangement}


{Exclusion|Exemption} {method|technique|approach}:


If there are {multiple|several|numerous} {devices|gadgets|tools}, {and|as well as|and also} {only one|just one} {device|gadget|tool} {finds out|discovers|learns|figures out} with {a problem|an issue|a trouble}, if it's not the {device|gadget|tool} {problem|issue|trouble}, there {must|should|need to|have to} be something {outside of|beyond} it that {causes|triggers|creates} this {specificity|uniqueness}


If there is {more than|greater than} one {equipped|geared up|furnished|outfitted} with the {same|exact same|very same} {problem|issue|trouble}, it is {unlikely|not likely} that {all of|every one of} the {equipment|devices|tools} {will|will certainly} be {broken|damaged}, {and|as well as|and also} there {must|should|need to|have to} be {one and the same|identical} {factor|element|aspect|variable} that {causes|triggers|creates} all {equipment|devices|tools} to have the {same|exact same|very same} {failure|failing} {characteristics|qualities|attributes|features}. So {finding|discovering|locating} the {same|exact same|very same} {point|factor} is the {key|essential|crucial|vital} to {finding|discovering|locating} the {source|resource} of the {failure|failing}


If there is {more than|greater than} one {equipment|devices|tools} in a system {and|as well as|and also} you are {concerned|worried} {about|regarding|concerning} the {cause of|reason for|root cause of|source of} the {malfunction|breakdown} {due to|because of|as a result of} {mutual|shared|common} {influence|impact}, {consider|think about|take into consideration} {using|utilizing|making use of} {dichotomy|duality} to {evacuate|leave} all {equipment|devices|tools}, which {helps|assists|aids} to {speed up|accelerate|quicken} troubleshooting. {For example|For instance|As an example}, A system has 8 controllers, {consider|think about|take into consideration} {disconnecting|detaching|separating} the {back of|rear of} 4, {then|after that} {disconnect|detach|separate} the {remaining|staying|continuing to be} 4 of {the two|both}.
