ABOUT AquaLink RS HOME AUTOMATION

Now you can integrate Jandy's AquaLink RS pool/spa control system into your whole home network. With Jandy AquaLink RS Serial Adapters, you can add pool and spa control to your other RS-232 "intelligent" serial communication systems. AquaLink RS Serial Adapters plug into any existing control system that has an available serial RS-232 port. The adapter lets you access your pool and spa equipment from a home automation system, just as you access other "intelligent" equipment such as lighting, security systems, audio/video and much more.

From a control panel of a home automation system such as AMX, Vantage, Crestron, Elan and others, you can view the status of pool and spa equipment, turn on/off any device that is connected to the AquaLink RS, check water and air temperatures or change pool and spa thermostat settings. All equipment connected to an AquaLink RS can now be controlled via a home automation system.

ABOUT AquaLink RS SERIAL ADAPTERS

AquaLink RS Serial Adapters are interfaces that allow any device with an EIA-232 serial port to connect to a Jandy AquaLink RS Pool/Spa Control System: enabling the user to check equipment status and control a variety of operations.

The microprocessor within the AquaLink RS Serial Adapter translates simple ASCII commands received over the EIA-232 link into the protocol used by the AquaLink RS Power Center and its connected devices. Responses from the AquaLink RS Power Center are then translated back to the home automation system in a simplified ASCII format via the EIA-232 link.

The PhastLink Serial Adapter is designed to be plug-n-play with simpler installation due to preprogrammed commands.

Power for the Serial Adapter is provided by the AquaLink RS Power Center on the same cable used for the EIA-485 communications. The Serial Adapter supports a wide range of EIA-232 data rates and can be operated with a simple 3-wire interface.

The AquaLink RS Serial Adapters also support connection to a standard external modem using an off-the-shelf cable with a serial gender adapter.

INSTALLATION OVERVIEW

Up to two (2) AquaLink RS Serial Adapters can be connected to the EIA-485 control interface of the Jandy AquaLink RS System. All connections to the AquaLink RS Power Center are via the Red 4 pin terminal bar (J2). Connections to the EIA-485/power cable are shown in Figure 1. Requires AquaLink RS software REV" I" or higher.

The EIA-232 device is connected to the DB-9S connector at the end of the nine conductor ribbon cable. The ribbon cable is plugged into the AquaLink RS Serial Adapter PDB at J1. Jumper headers JP1 through JP4 are used to configure Serial Adapter reset options (described in section 3.6 of the Owner's Manual).

AquaLink RS SERIAL ADAPTER CONCEPT

HOST PROTOCOL - EIA-232 CONFIGURATION

The AquaLink RS Serial Adapter appears as an EIA-232 Data Communication Equipment (DCE) device. As such, the nine pin DB-9 connector from the Serial Adapter can be connected directly (i.e., via cable wired straight through) to a DTE device such as the standard DB-9 serial port connector of a PC. Basic communications require no special cabling 1.

INTERFACE SIGNALS SUPPORTED

The AquaLink RS Serial Adapter supports the EIA-232 signals listed below. Please note that pin 6 of the DB-9 is unconnected at the Serial Adapter. Pins 1 and 9 are unconnected by default, but can be connected by installing jumpers JP5 or JP6 respectively on the Serial Adapter PCB. Pins 1 and 9 would normally not be used unless an external modem is connected to the Serial Adapter. Please refer to section 4.4 of the Owner's Manual for information on using an external modem with the AquaLink RS Serial Adapter.

MINIMAL INTERFACE CONNECTIONS The simplest functional connection between an external EIA-232 device and the AquaLink RS Serial Adapter requires connection of DB-9 pins 2, 3 and 5 only.

DATA FRAMING The AquaLink RS Serial Adapter utilizes the following serial data format:

.8 data bits, 1 start bit, 1 stop bit, No parity
