pass it on. An example of a case where the command is executed but not passed on is the start-
stop record command. The first upstream device capable of logging internally will execute the
command, but not pass it on.
As said before, the first device is special because it is the synchronization source for the entire
chain. By plugging its IN-port with the supplied terminator connector, a device can detect that
requirement when it powers up. The terminator connector just connects the transmit and receive
line of the IN-port together. Each device sends a special command out on it’s IN port when it
powers up. This command is ignored and not passed on by any device if received on it’s OUT
port. If the sending device immediately receives that command on its IN-port again, because the
terminator is plugged in, it assumes it is the first and special device in the chain. The LM-1,
having only one serial port, is ALWAYS a special device and MUST be connected to the
beginning of the chain.
NOTE: The DL-32 can only record data from devices chained to its IN port.
Data from devices chained after its OUT port can’t be recorded.
The following are some examples of Log-Chains using the DL-32 and other MTS devices.
2.1 Log-Chain of 5 channels consisting of DL-32 alone.
Note: Early version of the DL-32 do not require a terminator plug.
2.2 7-channel Log-Chain example with 2 AFR channels.
Notice that the LC-1’s are connected BEFORE the first DL-32. LC-1’s should always be
connected before the first DL-32.
2.3 17-Channel Log-Chain example
The example chain consists of a LM-1/LMA-2, a LC-1, a LMA-3, a DL-32’s and 2 XD-16’s. In this
case the chain has 17 channels (6 from LM-1, 1 from LC-1 and 5 each from the LMA-3 and DL-
32).
