 \section{General Description}
-The 1124 Kasli 2.0 Carrier card is an 8hp EEM module, designed to run ARTIQ kernels sent from a host machine over the network. It supports up to 12 EEM connections to other EEM cards in the ARTIQ-Sinara family and up to three SFP connections to satellite carriers.
+The 1124 Kasli 2.0 Carrier card is an 8hp EEM module, designed to run ARTIQ kernels sent from a host machine over the network. It supports up to 12 EEM connections to other EEM cards in the ARTIQ-Sinara family and up four SFP connections, used for comunications with other carriers and/or Ethernet.
 
 Real-time control of EEM daughtercards is implemented using the ARTIQ RTIO system. 1ns temporal resolution can be achieved for TTL events.
 
-4 SFP Gb/s slots are provided for Ethernet or DRTIO communications. Communication with a host machine is supported over Ethernet, while the Distributed Real-Time Input/Output (DRTIO) system allows for the use of additional core devices (e.g. Kasli 2.0, Kasli-SoC) as satellite cards, capable of running subkernels or distributing commands from the DRTIO master.
+4 SFP 6Gb/s slots are provided. One may be used for Ethernet, which supports communication with a host machine. Remaining slots can be used by the ARTIQ Distributed Real-Time Input/Output (DRTIO) system, which allows for the use of additional core devices (e.g. Kasli 2.0, Kasli-SoC) as satellite cards, capable of running subkernels or distributing commands from the \mbox{DRTIO} master.

-Kasli 2.0 features an XC7A100T-2FGG484I Xilink Artix-7 FPGA to facilitate reconfigurable high-speed real-time control of inputs and outputs. Most commonly, this FPGA is flashed with binaries compiled from the ARTIQ (Advanced Real-Time Infrastructure for Quantum physics) control system, which equips the carrier board with specialized gateware for handling other Sinara EEMs and an on-FPGA CPU for running ARTIQ experiment \mbox{kernels}.
