2. GETTING STARTED
2.1. INSTALLATION
For installation of the MAXnet you will need a computer with either an Ethernet or RS-232 connection or
both.
Read through the following two sections before beginning the installation. Do not turn on the power to the
MAXnet until you have properly configured the controller per the following instructions. Note that the
header at location J2 is used to choose the mode of communication (Ethernet or RS-232). The MAXnet is
set for RS-232 communication mode from the factory.
Though the MAXnet is a low power device, there should be ventilation, including forced air, around the
circuit board.
2.2. CONFIGURING
COMMUNICATION
The first requirement for communication through the RS-232 interface is to ensure that the MAXnet is
securely and safely mounted where damage is unlikely. This includes the exposure to possible static
discharge, moisture, debris, etc. Special mounting efforts may be required to protect the extended pins
on the bottom of the MAXnet.
CAUTION:
The RS-232 communication port is a DTE com device so that straight connection can be used for
communication; RxD to TxD, TxD to RxD. Two handshake signals are supported, CTS and RTS, that
can also be connected straight through, baud rates of 9600, 19200, 38400, 57600 and 115200 are
supported. Any terminal device that supports these signals and baud rates, be it a computer, dumb-
terminal, etc., can be used to communicate to the MAXnet.

Select an unused COM-Port, COM1, COM2, etc., on the computer or terminal to be used. Set the baud
rate and other communication parameters on the PC to match the default settings of the MAXnet.
Connect a straight-through 9-pin RS-232 cable between the host terminal and the MAXnet. To prevent
motors, switches or other devices from unexpected activation do not connect the cable to output
connector J1 at this time.
The MAXnet is a static sensitive device and standard Electro Static
Discharge (ESD) techniques are required when handling and installing the
MAXnet.
