ELP guides to Legacy Chipset Programming
Legacy chipsets have been around for years, originally with a black lid, and more recently in a red seal lid. This programming procedure only works on receivers with a red seal in the lid.
ELP Engineering Guide to Lodar transmitter pairing – (2025 onwards) for Blue seal lids
TI chipsets have been around since 2016 and have a blue seal in the lid. This programming procedure only works on receivers with a blue seal in the lid. and systems which have a model number ending in -CHn, where the n is a number, i.e -CH2 (our standard narrow band frequency).
