Chapter 1 Introduction to the PowerGate™ Modem
The PowerGate™ modem constitutes an ideal way to connect any PC application, including the
PowerBus™ software tools, to the PowerBus™ devices via a RS-232 interface. It may also be
used by any other RS-232 device that needs to communicate with other PowerBus™ device.
Users should refer to the PowerBus™ Glossary (document #G-PWB-0100) for a description of all
PowerBus™ related terms and definitions mentioned in this document.
1.1 Key Features and Benefits
•Integrates the Domosys U-510 series IC, which makes it possible to configure remote U-
510 / U-520 series IC based devices and properly monitor the network traffic using
software applications such as the PowerBus™ development Tool, PowerBus™ Installation
tool and PowerBus™ test tool.
•Allows developers to easily interface PowerBus™ logical networks via a standard RS-232
connector using a simple set of commands. Refer to the PowerBus™ U-510 / U-520
series IC datasheet for a description of the protocol.
•Connects to the PowerBus™ AC power line medium using the PowerBus™ AC adaptor
(included in the package).
•Can be used both as a modem and a device.

2.2.2 Power Input Connector
This connector is a polarized 8-pin DIN connector. It is used to provide power to the PowerGate™
modem and couple the PowerBus™ signal to the communication medium.
The AC-to-DC power adapter converts AC power (120, 240 VAC at 50/60 Hz) into a regulated 16
VDC. All power adapters include a PowerBus™ coupling circuit.
Note: ONLY the power adapter provided with the PowerGate™ modem can be used with
the PowerGate™ modem.

Chapter 3 Installation and Configuration
3.1 Connecting the PowerGate™ Modem
The PowerGate™ modem is configured as a Data Communication Equipment (DCE). Use a
regular DB-9 male to DB-9 female serial cable to connect to your equipment serial port.
Figure 3 Connecting the PowerGate™ Modem
Follow the steps below to install the PowerGate™ modem system (see Figure 3 Connecting the
PowerGate™ Modem):
1. Connect the power adapter DIN connector on the PowerGate™ modem. This connector
mates with the DIN connector on the rear of the modem.
Connect your host device (computer) to the PowerGate™ modem serial port. If the host is a
computer, connect the RS-232 standard modem cables between the COM1 or COM2. If the host
device is a DCE, use a null modem cable.
2. Plug the power adapter unit into any electrical outlet close to your computer.
3. Turn ON the PowerGate™ modem by toggling the main power switch, located on the rear
of the modem, to the upper position (ON).
