ML-OA-RS232 – Option board
Option board to add a secondary accessory to our data loggers
Some of our data loggers are provided with an RS232 port to connect an accessory, an accessory is considered a device not being a typical sensor/actuator.
The currently available accessories are: a TFT-display, a JPG-camera, a GPS-receiver or an Irridium satellite transceiver.
An ML-OA-RS232 option board can be used to add a secondary accessory to a data logger with a primary accessory port. So you can, in example, connect a TFT-display together with a camera now or create a dual camera system (e.g. to take pictures in opposite directions at a critical point in a trajectory).
BEFORE YOU GET STARTED
Some useful notes
Accessories can be powered from the 5V@800mA output of the accessory port, unless a) the combined draw exceeds 800mA, b) the secondary accessory should be switched on at different times, c) an accessory requires a voltage other than 5V. The ML-OA-RS232 option board has a control output to switch on an alternative power source, e.g. an ML-OP-524 when connect to its control input.
