TDL450B Data Cable, R12/R12i (7P Lemo to 5P Lemo)        

The Trimble TDL450 Radio Data Y Cable connects standard high-power base radios like the TDL450 or HPB450 to GNSS receivers such as the Trimble R12 and R12i, though note that specific newer models like the TDL450B often use distinct serial data configurations (part number 130918) rather than the standard 7-pin to 5-pin Y-cable. 7-pin ruggedized #0 Lemo (to the GNSS receiver) to 5-pin #1 Lemo (to the radio) with an integrated SAE connector for 12V external power. Delivers simultaneous power and data link (RTK corrections) between the battery, receiver, and radio base setup.
