Introduction: The AQ-CO-SERIAL is a serial home automation module that
provides a command set which enables any attached system to fully emulate
an Aqua Logic PS pool control running software rev 2.2 or later or any Pro Logic
PS pool control. Thus, buttons can be transmitted, and the Aqua Logic PS/Pro
Logic PS LED and messaging display states are returned.
A complete description of the operation of an Aqua Logic PS or Pro Logic PS
can be found in the user manuals at
www.goldlinecontrols.com.
Tools Needed:
-RS232 Cable (Straight through Male to Female DB9 Cable, 25' max)
-Four conductor low voltage control wire up to 100 feet (RS-485 wiring)
-Aqua Logic PS model pool control with Rev: 2.2 or later firmware
OR
Pro Logic PS model pool control
Functionality:
The AQ-CO-SERIAL interconnects an RS-232 bus from any Home Automation
system with the Aqua Logic PS/Pro Logic PS using the powered RS-485. A
typical system is shown below.

RS232
& Power
Power:
The AQ-CO-SERIAL is powered via RS485 from the Aqua Logic PS/Pro Logic
PS control.
Typical Setup:
The RS-232 end is connected to the Home Automation System and the RS485
end is connected to the Aqua Logic PS/Pro Logic PS. The AQ-CO-SERIAL
enclosure is 5" X 5.25" X 1.25" and is designed to be mounted indoors only.

Refer to the diagram below. The Home Automation system is connected to
the RS232 (J3) connector. To communicate with Aqua Logic PS/Pro Logic
PS, the connectors J2 or J4 are used. (J2 and J4 are connected in parallel
internally).

The Aqua Logic PS/Pro Logic PS communicates to its peripherals via a half
duplex asynchronous RS-485 link that also supplies DC power. All peripherals
are wired in parallel on this bus. The Aqua Logic PS/Pro Logic PS is the
master of the bus, and devices only transmit when queried. For example, to
receive a keypress from any one of the remote controls, the Aqua Logic PS/Pro
Logic PS requests pending keys every 100 ms, and then listens for an answer.
If any remote control has a pending keypress, it is immediately sent back to
the Aqua Logic PS/Pro Logic PS.
The AQ-CO-SERIAL relieves the Home Automation system from having to respond to the Aqua Logic PS/Pro Logic PS timing and command response
requirements. It is a simple board with a processor, a ground isolated RS232
interface via DB9 connector, and a terminal strip for connection to the Aqua
Logic PS/Pro Logic PS bus. It performs as a slave to Aqua Logic PS/Pro Logic
PS and as a bi-directional interface to the Home Automation System. All the
commands needed to emulate a remote control are supported: sending a
keypress to the Aqua Logic PS/Pro Logic PS, and receiving text and LED
status.
The Aqua Logic PS/Pro Logic PS-16
has 16 internal relays. The PS-4 and
PS-8-V has 4 relays. The PS-8 and
PS-16-V has 8 relays. The “V” models double the AUX buttons for use
as macro buttons called “groups”. The
image on page 2 is of a PS-16 remote with all keys un-labeled. The
remote is shipped with adhesive labels which allow customization of the
keyboard. The same list of labels are
available in the system software so
that a relay or valve can be more appropriately named.

Shown below is a labeled remote control to a Pro Logic PS pool control. Note
that labels have been placed over the generic names to make the keys human
readable. In this case, the Pool Filter, Gas Heater, Spa Filter and Water Feature are all turned on.
These names also have been selected in the Aqua Logic PS/Pro Logic PS
configuration menu so that when the user presses “Spa Jets” a message says
“Spa Jets Turned On” appears on the display.
Note that buttons may not respond under certain conditions. For example,
pressing “Cleaner” while the Pool Filter is OFF, will result in the message
“Interlock prevents turn on” being displayed and the LED will not light up.
There are many such special features and interlocks in the Aqua Logic PS/Pro
Logic PS.
The menu button selects the Aqua
Logic PS/Pro Logic PS menus.
The navigation keys surrounding
the menu button allows movement
through sub menus (“<“ and “>”)
and value changes (“+” and “-”).
All feedback is via the 2 x 20 alphanumeric display.
The menus are mainly used to
configure the pool and change
temperature setpoints. Most user
interaction is via the direct-access keys in the lower half of the control.
Command overview:
These are the standard commands which are used for communicating between the Home Automation (HA) and the AQ-CO-SERIAL. To keep this system simple, these commands are very similar to the commands used on the
Aqua Logic PS/Pro Logic PS bus.
Hex Command
01 Update Key Pad Press (HA to AQ-CO-SERIAL)
02 Update Key Pad Release (HA to AQ-CO-SERIAL)
03 Update LEDs (AQ-CO-SERIAL to HA)
04 Update Display (AQ-CO-SERIAL to HA)
05 Beeper (AQ-CO-SERIAL to HA)
