The Edge Accessory System (EAS) was created with future expandability in mind. The architecture of the EAS allows users to connect multiple accessories, daisy-chain style, to the CS and CTS platform. The ability to daisy-chain multiple accessories using the EAS allows users to monitor and display dozens of parameters on a single device. *EAS Starter Kits are only available to work with the CS and CTS product lines. In order to use the EAS accessories you must have an EAS Starter kit (part # 98602). EAS Starter kits come with all Juice w/ Attitude CS and CTS products and the EAS Starter Kit w/ Expandable EGT (part # 98603).
