Aquaread BlackBox™ Instruction Manual
10401-00618 Rev P
2. Wiring Overview
The BlackBox is supplied with a screened multicore cable for connection to a variety of
third party controller devices. This 6 core cable provides power in to the BlackBox and
serial data out. If you have chosen to order a unit with the optional analogue channels, the
BlackBox will be supplied with a 10 core cable.
Any cable cores that are not being used MUST be trimmed back and insulated from one-
another, the power supply and ground. The screen (or shield) of the cable should be
connected to chassis ground at the controller.
2.1. Important Information Regarding the Power Supply
If the Aquaprobe you are attaching to the BlackBox includes a
depth measurement
sensor
(AP-700-D, AP-800-D, AP-2000-D, AP-5000 or AP-7000), power
must
be left applied to
the BlackBox at all times. See section
4.3 Important Information Regarding Depth
If power saving is required, the white core (On/Off switch line) should be
used to put the BlackBox to sleep.
If you are installing an AP-7000 with the BlackBox, power
must
be left applied to the
BlackBox at all times. See section
8.4.23 Important note concerning AP-7000 self cleaning.
2.2. The Multicore Core Cable
The table below gives an overview of the cable core designations for the six/ten-core
power/data cable. If you have not requested activation of the analogue channels, your
BlackBox will be fitted with a six core cable. Please refer to the individual application wiring
diagrams in the next section before making any connections.

2.3. SDI-12 / Modbus Selection
The yellow core is used to select between SDI-12 or Modbus (RS485) serial data
communications. Tying the yellow core to the +ve power supply will configure the digital
output as Modbus (RS485). Tying the yellow core to ground will configure the digital output
as SDI-12. Please note: the yellow core must not be left floating.
2.4. Sleep Mode When Configured for Modbus Output
The white core can be used to put the BlackBox into a low power sleep mode. If the white
core is taken to a voltage above 6V, the BlackBox will run continuously and readings will be
refreshed every 2 seconds. If the white core is taken to ground, the BlackBox will enter
sleep mode.
