1.2 Ranges and Method of Transmission
It is not possible to exactly predict the distance over which the Pro Max system will
perform. Several factors may affect the distance and reliability of any radio
transmission:
•Frequency used •Transmission Power
•Terrain •Antenna placement
•Building Structures •Weather conditions
•On channel interference •Atmospheric disturbances
•Antenna types •Mode of operation (AM, FM, etc.)
Your Pro Max system has been designed to operate at distances up to one mile. Under
ideal open field conditions, it can readily operate up to 5 miles.
When attempting to use Pro Max over extended distances, it is important to ensure that
the receiving antenna is properly located. If possible, avoid Pro Max receiver antenna

Rain Master Irrigation Systems Pro Max User’s Manual
Page 4
locations, which are indoors, especially basements, or structures, which are concrete
and steel. It may be possible to remotely locate an external antenna whenever poor Pro
Max receiver locations exist. Call Rain Master Technical support for assistance,
telephone [phone]. Moving the Pro Max transmitter to a more favorable location
or usage of optional high gain antennas on both the Pro Max transmitter and Pro Max
receiver may improve operations.
The Pro Max system utilizes VHF/FM communications and the Pro Max receiver/Pro
Max transmitter pair are factory encoded to insure that other services including other
Rain Master remotes, do not interfere or false trigger the Pro Max receiver. Digital
filtering further enhances operation in interference prone environments. FM
transmission is employed for its inherent quality and immunity to atmospheric, static,
and electrical interference which are commonly found in AM types of equipment such as
citizen’s band radio, garage door openers, etc. Usage of FM transmissions also insures
that the stronger signal prevails (capture ratio), meaning that all received signals, which
are weaker than the Pro Max transmission, are completely overridden.
Note: Antennas are not just a piece of wire; they are cut for a precise
frequency of operation in order to ensure optimal performance. When
using antennas with the Pro Max system, only utilize Rain Master
specified parts, which are available through your authorized Rain Master
distributor.
1.3 Licensing Information

The Universal Adapter is equipped with a 35-conductor connection cable RMIS Part
Number 32PC, which must be physically wired to each station of the generic controller.

Rain Master Irrigation Systems Pro Max User’s Manual
Page 14
Note: If you have purchased model PROMAX-UA and you need to
connect to a Rain Master controller, the Universal Adapter box (PM-
UDAPT) is not required. Refer to section 2.0 for installation and
operation.
In cases where the controller does not provide the required 24 Volts AC, a step-down
transformer is employed to convert standard 117 Volts AC or 220 Volts AC to 24 Volts
AC.
3.1 Using the Promax-UA Universal Adapter with a Non Rain Master Controller
The controller serves only two purposes when using the Universal Adapter.
First, it provides 24 Volts AC for the Pro Max receiver. Never allow more than the
“normal” 24 Volts AC (up to 28 Volts AC maximum) to enter the Pro Max receiver
through the wires designated for 24 Volts AC. If the controller runs ON a voltage other
than 24 Volts AC, use a step-down transformer to convert the voltage to 24 Volts AC for
input to the Pro Max receiver. Transformers that convert higher voltages to 24 Volts AC
are available from Rain Master.
Secondly, the controller serves as a point of connection for the field wires and the Pro
Max receiver’s output. Usually the point of connection is the terminal strip or a quick
disconnect within the controller or pedestal. Rain Master offers several types of
connector cables for wiring to the controller. The RMIS Part Number 32PC or RMIS Part
Number 24PC Permanent Connector Cable, which is intended to be permanently
connected to the controller. The other is the RMIS Part Number 32TC Temporary
Connector using alligator clips.
3.2 Installing the PROMAX-UA System
To install a Permanent Connector, follow the instructions below. Prior to installation,
please observe the following precautions:
CAREFUL CAUTION DANGER
WARNING: STOP – PLEASE READ ALL INSTRUCTIONS
AND THE FOLLOWING WARNING MESSAGES
BEFORE OPERATING THIS EQUIPMENT.
Always use with the approved Rain Master cable connector assemblies (RMIS Part
Number 24PC, RMIS Part Number 32PC, RMIS Part Number 32TC, RMIS Part Number
32EX) Use of any other connector will void the warranty and may damage the Pro Max
remote control system.
NEVER allow more than the “normal” 24 Volts AC to enter the Universal Adapter
on any of its wires. If there is any question about a connection voltage, check the
voltages with a voltmeter.
NEVER operate the Pro Max transmitter without the CORRECT antenna properly
installed.
NEVER connect the Universal Adapter to more than one controller at a time.

Rain Master Irrigation Systems Pro Max User’s Manual
Page 15
Procedure (Refer to Figure 7)
Step 1 Remove power from the controller.
Step 2 Connect a single wire to each station (up to 32) of the RMIS Part
Number 32PC wiring harness at the controller’s terminal strip. The field
wiring should remain connected and in place. Simply add the RMIS Part
Number 32PC wiring to it. Make sure to follow the station color code-
wiring list illustrated ON the back cover of this manual.
Note: The chart defines the connections for the following
cables: RMIS Part Number 32PC (supplied with
PROMAX-UA), RMIS Part Number 24PC, 12PC, and
RMIS Part Number 32TC.
Make sure that any unused station wires on the PC cables are insulated
and will not short to any metal object.
If there is a Master Valve and/or Pump in the system, make sure you
understand how they are controlled before hooking up the Master Valve
and/or Pump wire of the Permanent Connector. If there is any doubt -
find out before connecting it - voltages above the “normal” 24Volts AC
will damage the Pro Max Pro Max receiver unit.
If the Controller Supplies 24 Volts AC to activate the Master
Valve/Pump, then connect the Master Valve/Pump wire of the
Permanent Connector to the controller’s Master Valve/Pump terminal.
If the Controller acts as a switch to activate the Master Valve/Pump
Finding two terminals in the controller associated with the Master
Valve/Pump usually, but not always, indicates that a relay will be
required. The relay is wired such that its coil terminals are activated by
the Master Valve/Pump and COMMON of the PC and its switch contacts
are in parallel with the controller’s two terminals, see Figure 4 below.
Figure 7: Relay (such as Rain Master RLY1)
Step 3 Connect the wire for the PC Cable COMMON to the COMMON terminal
of the controller.
Step 4 Important! If 24 Volts AC is not available from the controller’s terminal
strip, see Section 3.5 and skip to Step 6 below.

Step 5 Connect the wire from the PC cables 24 Volts AC to the 24 Volts AC
terminal of the controller. Note that the PC cable has only one wire for 24
Volts AC despite the controller having two 24 Volts AC terminals. This is
because the controller takes one of its 24 Volts AC terminals and
connects it to the COMMON terminal and you have already attached the
PC cables COMMON wire to the controller’s COMMON terminal.
You must find which 24 Volts AC terminal on the controller is NOT
electrically the same as the controller’s COMMON terminal and connect
the PC’s 24 Volt AC wire to it.
Using a voltmeter, power up the controller and set the voltmeter on a 30
Volts or higher AC scale. Place one of the voltmeter leads ON the
controller’s COMMON terminal and use the other lead of the meter to
read each of the 24 Volt AC terminals. Connect the PC cables 24 Volt
AC wire to whichever terminal gives a reading of 24 Volt AC on the
meter.
If the controller does not have any terminals marked 24 Volts AC then
leave one of the voltmeter leads ON the controller’s COMMON and try
the other lead of the meter to measure the low voltage wires ON the
secondary of the controller’s transformer. Connect the PC cables 24
Volts AC wire to whichever terminal provides a reading of 24 Volts AC
ON the meter.
Step 6 Place the Rain switch in the OFF or Rain position.
Step 7 Connect the 9-pin female end of the PM-SER99 cable to the Pro Max
receiver and the male end to the universal adapter. Hand tighten the
screw locks.
Step 8 Align the large connector of the RMIS Part Number 32PC cable with the
connector ON the universal adapter and plug them together.
Step 9 Reconnect power to the controller. Refer to the following table:
Upon Receiver Connection

2 Beeps Multi-Pro Max receiver mode:
•Requires corresponding access code to enable
Pro Max receiver operation.
3 Beeps Failed internal diagnostic tests. Contact Rain Master.
No Beeps Check the 24 Volts AC and COMMON connections.
3.3 Temporary Connector Installation
The RMIS Part Number 32TC Temporary Cable is wired in the exact same fashion as
the Permanent Cable Connector described above except that it uses alligator clips for
connection to the terminal strip within the controller so that it may be easily installed and

Rain Master Irrigation Systems Pro Max User’s Manual
Page 17
removed. Follow the connection instructions for the permanent connector, be very
careful that the alligator clips are secure and not “shorting” to any metal or each other.
3.4 Disconnecting the PROMAX-UA from a Non-Rain Master Controller
To disconnect the universal adaptor, use the following procedure:
Step 1 Disconnect the large 37 pin connector plug from the universal adaptor by
grasping the plug’s body, not by the cable, and pull straight out.
3.5 Non-Rain Master Controllers Lacking 24 Volts AC
24 Volts AC is required to power the Universal Adapter. If 24 Volts AC is not available
from the controller, use a step-down transformer to convert from the line voltage
(usually 117 or 240 Volts AC) to 24 Volts AC and run the 24 Volts AC wire into the PC
cable to the two wires designated for 24 Volts AC and COMMON. There is no need to
worry about the polarity of these two connections. Additionally, connect the PC cables
COMMON wire to the controller’s COMMON terminal. Do not connect the PC cables 24
Volts AC wire to the controller.
