RMM Rack Mount Modems; Quick Start Guide
1. Introduction
This Quick Start Guide describes a simplified installation procedure for our RMM units,
which will allow you to communicate with the unit in order to demonstrate basic features
and check for proper operation. Note that this Quick Start Guide
does not provide a detailed description of unit configuration,
or discuss advanced operating features in detail. For more
information, please refer to the RMM User’s Guide, which can be
found on our web site at the address below, or by scanning the QR
Code to the right.

2. Hardware Installation
2.1. Apply Power to the RMM
Refer to the safety precautions listed at the beginning of this Quick Start Guide and to
the power rating nameplate on the RMM unit, and then connect the unit to an appropriate
power source.
AC powered RMM units can be connected to 100V to 240V AC power. DC powered
RMM units can be connected to ±18 to ±72 Volt DC power. When power is applied to the
RMM, the Input Power A and Input Power B indicators should light.
Note that the presence of two power inlets allows the RMM to be connected to both a
primary power supply and secondary power supply to provide power redundancy for
mission critical applications. For both AC and DC Powered RMM units, connect your
primary power supply to the RMM's Input A inlet. Connect your secondary power supply
to the Input B inlet.
2.2. Configuration
2.2.1.
Default Configuration
In the default condition, the RMM is configured as follows:
• 9600 Baud, RTS/CTS Handshaking, 8 Data Bits, 1 Stop Bits
• Answer on first ring
• Audible Buzzer On
• Echo On
• Result Codes Off
If these parameters are compatible with your application, then there is no need to
reconfigure the RMM unit. In this case, connect the modem port cable and phone line
cable as described in Section 2.2.4. Note however that if you want to change modem
parameters, you must access the modem configuration menu as described in Sections 2.2.2
and 2.2.3.
