Spectra Programming

[rescue161]

What is the exact fault that the RSS displays?

 

[Muxlow]

in the top right it says power fault
then a pop up windows says

serial bus communication error
check radio power and interface cables.
press f2 to retry

 

[rescue161]

The radio is powered on right?

 

[Muxlow]

yup. i took the power cable off, then connected the acc cable, then to the rear of the radio then to the rib, put the power wire back into the radio, radio powers up normal...
is there some type of programming mode or somethign it has to be in or something i have to do first.
radios on like normal and such

 

[rescue161]

Nope, there is no programming mode. What happens when you're in the F9 where you change the comm port and you press "F6" to test the ports?

 

[Muxlow]

same thing. serial bus failure; power fault

 

[rescue161]

Sounds like the cable is bad. Have you Ohm'd out the leads? The RIB is good right?

 

[Muxlow]

rib works. used it to program a stx last night. its a maxton rpc-mrib

Spectras are a bit more involved with communications than the STX line. They are very picky about what kind of RIB you use on them. If the cable checks out on a meter, then I'd suspect the RIB is not giving the Spectra what it wants.

 

[Muxlow]

what should i check on the cable

 

[rescue161]

Continuity. Make sure the connections are right and actually will conduct.

 

[Muxlow]

we found that one of the pin outs was the wrong wire on it. we had 2 of the same colour wires and connected the wrong one. its pin 7 speaker low
hope thats the problem

There are a lot of RIB's out there that are cheaply built and don't include all the circuitry necessary to program a Spectra.

You might want to check the manufacturer's specs and see if it will program a Spectra.

sys it can do all of these

You have to be VERY careful when dealing with the speaker circuit in this radio (Spectra). If you tie either of the speaker leads to ground (I sure hope that wasn't the wire that got switched) you'll blow the audio circuit and the radio won't make any sound anymore.

 

[Muxlow]

it was hooked up to nothign at all on the other end. i striped a printer cable and used the db25 end of it and cut the wires and rehooked them up to the the db15's and the db25

 

[rescue161]

That's good. Just be careful in the future around those audio pins.

Have you verified all the other pins?

 

[Muxlow]

yup. just testing the last one now

 

[Muxlow]

nope. still dotn work. does the same thing
power fail

 

[Muxlow]

i think i know why it wont work.
i have a little power inverter in the house. it powers the radios but i cant transmit on them or it resets the inverter. maybe thats why its not working. becaue its not getting th e12 volts power

it has a 12vdc output power on it
