VPU-12 Programming
To program Midian VPU-12 Encryption Modules in either a TM8000 or a
TOP radio usually requires a hard-wired connection from the Midian
programmer to the module. This requires opening the radio and connecting
the dedicated programming cable (provided with the Midian programmer)
to pads on the Tait flex or board.
Important
Each encryption module is provided with a sheet for
recording programmable settings. As Midan VPU12 mod-
ule settings and TVS-2 encryption codes cannot be read
back, it is strongly recommended that all settings be recorded
for each fitted module and kept in a secure place.
