Description

The MOST150 Repeater includes single signal recovery. It can be used for replacement of a defective device, as well as adding more MOST150 devices to the MOST® network when used as an extender. The transmit (Tx) line of the repeater’s extension side can be connected to a monitoring device, such as an OptoLyzer® G2 3150o, to spy MOST150 network traffic without changing the number of active network nodes.

Block Diagram:

Once the MOST150 Repeater detects light, it switches on almost immediately. It also supports slave wake-up, meaning that the extension side is able to wake-up the main ring by powering on the device after light has been detected on the extension’s side. Additionally, the repeater has a switch-off mechanism which activates when no light is detected for a specific length of time.

When light is sensed on the receive line (Rx), a short circuit protected relay-switched lock contact closes. Because of this, the MOST150 Repeater is capable of looping an externally provided power signal through the closed relay contact, which can be very helpful for powering an external device, such as used for data logging and storage.

For simple power and lock indications, the MOST150 Repeater provides status LEDs on the main and extension sides.
