TS-480 JMP2 position
« on: 2015-02-01, 18:29:54 »
Hello,

I've started to configure my TS-480SAT to work with RRC. Reading through manual I found a mismatch regarding JMP2 that will select 8 or 9V.
On the RRC-1258 MKII manual, pag 23:
"JMP-2 is used to select if the DC-power to the front panels should be 8 or 9 V. With the strap in place it will be 8V, which fits all ICOM radios. Without the strap the voltage will be 9V, which fits Kenwood TS-480 and RC-2000 panels that need 9V for the back-lighter"
So, for  TS-480, I understand that JMP2 should not be connected.

On page 182, "Kenwood TS-480", first of all it should be a mistake regarding radios serial number:
"New radios with serial number from 70600056 are using Configuration type 1 and older radios with serial number below are using configuration type 2."

 70600056 is not a serial number specific to TS-480 radios, for example my TS-480 serial number is starting with B48..... and it is manufactured in 2014, so I can consider is a new radio and should use "Configuration Type 1"
 
On this page, 182, on the table specific to Configuration Type 1, JMP2 is 1 (In place) that means we are using 8V for the front panel, but on page 23, for the same TS-480, it is specified JMP2 -> 0 (not connected).
Which one is the correct position ?

Thank you!

JMP 2 should not be in place to get 9V for the backlighter, the rest of the panel has it's own voltage regulator. It works in both positions but the backlighter will be brighter with 9V.

About the serialnumbers, that is the info we got from Kenwood several years ago, they may have changed there policy for creating serialnumbers after that.
