5. Connecting with other MTS Devices
In general, the OT-1 can be treated like any other MTS device. There are two caveats. The first
is that the OT-1 has a built in USB port which can be used in place of the Serial OUT port for
connecting to a computer:
It is important to understand that only devices ‘up stream’, or attached to the Serial IN on the OT-
1 can be seen and logged via the OT-1’s USB port. Also, only gauges and displays ‘down
stream’ of the OT-1 will be able to display OT-1 channels.
When other devices are chained ‘up stream’ from an OT-1 the OT-1’s MTS indicator can be used
to determine proper connectivity of all devices attached to the Serial IN of the OT-1:

If the light is not blinking, or is blinking erratically, then the serial connections prior to the OT-1
should be checked.
The second caveat is that the terminator plug, or ‘Arnold’, which is often referred to in general
MTS instructions is not required when no device is connected to the OT-1’s Serial IN port. A
terminator will not hurt the OT-1. In fact, it would help protect the connector from dirt and debris.
But, should a terminator not be available (and they do tend to grow legs, even when attached to a
large object, ala’ a gas station restroom key), none is required.
