Master 810/2410

Master network controllers provide sensor power and laser safety, and broadcast system-wide synchronization information (i.e., time, encoder count, encoder index, and digital I/O states) to all devices on a sensor network.

It is not necessary to power down a sensor's power source such as a Master before unplugging the sensor from the Master. (Sensors can be "hot-swapped.")

Laser safety is not supported by snapshot sensors.

Some sensors require a minimum input voltage of 48 VDC. Verify the accepted input voltage for your sensor in the sensor's specifications; for specifications, see Sensors.

The following table summarizes Master 810 and 2410:

Notes

1. Refer to sensor datasheets for additional power required by sensors.
2. Gocator only supports one digital input.
3. Supports open collector, pull-up resistor, line driver, push-pull, and TTL.

The following table describes the meanings of the encoder and sensor port LED indicators:

LED Indicators

Indicator	Description
Power	Device is on.
Safety	Indicates the status of the Laser Safety circuitry. The “On” state indicates that all sensor light sources are active.
Encoder A	Reserved
Encoder F	On continuously: Forward motion with no indexing is detected. Blinking: Forward motion with indexing is detected.
Encoder R	On continuously: Reverse motion with no indexing is detected. Blinking: Reverse motion with indexing is detected.
Input 1-4	Digital input ports 1-4 active.
SYNC IN and SYNC OUT Ports (Green and Orange LEDs)	Reserved.
Sensor Port Green LED	Indicates that a sensor is connected to the port and is powered up.
Sensor Port Orange LED	Not used.

Master 810 and 2410 can be mounted to DIN rails using the provided adapters (for more information, see Installing DIN Rail Clips: Master 810 or 2410 ). The units are also provided with removable adapters for 1U rack mounting; the mounting holes for this option are compatible with older Master models (400/800/1200/2400).

The Phoenix connectors on Master 400/800/1200/2400 are not compatible with the connectors on Master 810/2410. For this reason, if you are switching models in your network, you must rewire the connections to the Master.

Master 2410 can currently be used with encoders with a maximum quadrature frequency of 300 kHz.

Master 810 can be configured to work with a maximum encoder quadrature frequency of 6.5 MHz. For more information, see Configuring Master 810.
