+\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 EEM connection provides eight digital channels each.
+Each RJ45 connector exposes four digital channels.
+The direction (input or output) of each channel can be selected using DIP switches.
+Outputs are intended to drive 100\textOmega~loads, 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.

+\section{Example ARTIQ code}
+The sections below demonstrate simple usage scenarios of the 2245 LVDS-TTL card with the ARTIQ control system.
+They do not exhaustively demonstrate all the features of the ARTIQ system.
+The full documentation for the ARTIQ software and gateware is available at \url{https://m-labs.hk}.
+
+Timing accuracy in the examples below is well under 1 nanosecond thanks to the ARTIQ RTIO system.
+
+\subsection{One pulse per second}
+The channel should be configured as output in both the gateware and hardware.
+
+\begin{minted}{python}
+@kernel
+def run(self):
+    self.core.reset()
+    while True:
+        self.ttl0.pulse(500*ms)
+        delay(500*ms)
+\end{minted}
+
+\newpage
+
+\subsection{Morse code}
+This example demonstrates some basic algorithmic features of the ARTIQ-Python language.
+\begin{minted}{python}
+def prepare(self):
+    # As of ARTIQ-6, the ARTIQ compiler has limited string handling
+    # capabilities, so we pass a list of integers instead.
+    message = ".- .-. - .. --.-"
+    self.commands = [{".": 1, "-": 2, " ": 3}[c] for c in message]
+
+@kernel
+def run(self):
+    self.core.reset()
+    for cmd in self.commands:
+        if cmd == 1:
+            self.led.pulse(100*ms)
+            delay(100*ms)
+        if cmd == 2:
+            self.led.pulse(300*ms)
+            delay(100*ms)
+        if cmd == 3:
+            delay(700*ms)
+\end{minted}
+
+\subsection{Counting rising edges in a 1ms window}
+The channel should be configured as input in both the gateware and hardware.
+
+\begin{minted}{python}
+@kernel
+def run(self):
+    self.core.reset()
+    gate_end_mu = self.ttl0.gate_rising(1*ms)
+    counts = self.ttl0.count()
+    print(counts)
+\end{minted}
+
+This example code uses the software counter, which has a maximum count rate of approximately 1 million events per second.
+If the gateware counter is enabled on the TTL channel, it can typically count up to 125 million events per second:
+\begin{minted}{python}
+@kernel
+def run(self):
+    self.core.reset()
+    self.edgecounter0.gate_rising(1*ms)
+    counts = self.edgecounter0.fetch_count()
+    print(counts)
+\end{minted}
+
+\newpage 
+
+\subsection{Responding to an external trigger}
+One channel needs to be configured as input, and the other as output.
+
+\begin{minted}{python}
+@kernel
+def run(self):
+    self.core.reset()
+    self.ttlin.gate_rising(5*ms)
+    timestamp_mu = self.ttlin.timestamp_mu()
+    at_mu(timestamp_mu + self.core.seconds_to_mu(10*ms))
+    self.ttlout.pulse(1*us)
+\end{minted}
+
+\section{Ordering Information}
+To order, please visit \url{https://m-labs.hk} and select the 2245 LVDS-TTL in the ARTIQ Sinara crate configuration tool. The card may also be ordered separately by writing to \url{mailto:sales@m-labs.hk}.
