Need when user is having 3 or more micromanipulators. Each uMp-HUB has 4 plugs for uMp-micromanipulators (uMp-TSC + uMp-HUB = 6 manipulators; uMp-TSC + 2 x uMp-HUB = 10 micromanipulators etc.) The uMp-HUB includes also rechargeable lithium batteries providing more power for the uMp-system. The uMp-HUB is attached on uMp-TSC touch screen unit with ethernet cable.
Please note, that uMp-HUB unit includes uMp-CHG charger and uMp-ETH ethernet cable, you don’t need to order those separately.
