The 2118 BNC-TTL card is an 8hp EEM module; the 2128 SMA-TTL is a 4hp EEM module. Both TTL cards add general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
Each cards provides two banks of four digital channels for a total of eight digital channels, with corresponding connectors, respectively either BNC (2118) or SMA (2128). Each bank possesses individual ground isolation. The direction (input or output) of each bank can be selected using DIP switches, and applies to all four channels of the bank.

Each channel supports 50\textOmega~terminations individually controllable using DIP switches. Outputs tolerate short circuits indefinitely.

The 2238 MCX-TTL card is a 4hp EEM module. It adds general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
Each card provides four banks of four digital channels each for a total of sixteen digital channels, with MCX connectors in the front panel, controlled through 2 EEM connectors. Each individual EEM connector controls two banks independently. Single EEM operation is possible.

\section{General Description}
The 2245 LVDS-TTL card is a 4hp EEM module. It adds general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
Each card provides sixteen total digital channels, with four RJ45 connectors in the front panel, controlled through 2 EEM connectors. Each RJ45 connector exposes four digital channels in the LVDS format. Each individual EEM connector controls eight channels independently. Single EEM operation is possible. The direction (input or output) of each channel can be selected individually using DIP switches.

Each individual EEM connector controls eight channels independently. Single EEM operation is possible. The direction (input or output) of each channel can be selected individually using DIP switches.
Outputs are intended to drive 100\textOmega~loads and inputs are 100\textOmega~terminated. This card can achieve higher speed and lower jitter than the isolated 2118/2128 BNC/SMA-TTL cards. Only shielded Ethernet Cat-6 cables should be connected.
