Powering the Sensor using a DOT 24V Power Adapter is recommended during in-house use (e.g. configuration, bench testing). The DOT 24V Power Adapter can accept an input voltage of 100 - 264 VAC (47 – 67 Hz) from a wall outlet. The following instructions detail powering the Sensor from a wall outlet. -

The sensor uses a 115200 baud 8N1 Serial connection for general use. The Sensor can also be operated using an external controller without using DOT Suite through direct serial commands; users can request a list of base commands from DOT through email: Aftersales@DartmouthOcean.com. However, this is not recommended due to the safeguards built into DOT Suite that ensure proper operation. -

Ethernet port). For example, an IP address of 192.168.137.200 is a valid address for your sensor, which can be set in the application DOT Suite. Figure 10: Ethernet IP Address configured in Command Prompt. In this example, the IPv4 Address was set to 192.168.137.1. -
Page 29: Maintenance & Care
Sensor and Fluids Storage The A1000-200 Phosphate Sensor should be kept out of direct sunlight in a cool, dry area when possible. Reagents and standard should be stored in a refrigerator set to 4 °C when not in use to preserve their shelf-life. -
Page 30: Anode Replacement
A1000-200 Operation and Maintenance Manual (0001-03) Maintenance & Care Anode Replacement The water-facing metal components are made of anodized aluminum. The anodization is important in preventing corrosion in marine environments. Any scratch in the anodized metal parts will compromise corrosion resistance. Significant corrosion will make the part unusable, so great care should always be taken in handling anodized metal pieces, such as the sensor and reagent housings and end caps. -
