User's Guide
1. Introduction
The RMM Rack Mount Data/Fax Modem is designed for applications
that require a single “Industrial Strength” modem that easily installs in
equipment bays. The unit requires only 1 rack space, thus eliminating
the hassle of equipment trays and power bricks required for “Plastic
Box” modems.
Figure 1: Front Panel
The heart of the RMM is the popular and highly reliable U.S.
Robotics® Sportster® 28.8 modem card. The power supply is filtered,
fused and surge protected for operation in harsh environments. The
RMM is available in 115/230 (switchable) and 48 volt DC versions.
Features
Requires Only One 19 Inch Rack Unit.
·
High Speed ITU-T V.34+
·
Filtered and Surge Protected Power Supply.

4. Installation
4.1. 48 Volt DC Power Option
The 48 Volt DC input is not polarity sensitive. Therefore, you can
connect either positive or negative wires from your 48 volt power
source to either input and the internal circuitry will adjust for the proper
polarity.
Input Range: 40 - 60 Volts DC, 200 milliamps maximum.

5. Command Summary
Type commands in either upper or lower case. Do not use a
combination of upper and lower case characters.
·
·
·
Use the Backspace key to delete errors. Note that the original AT
command is stored in the modem buffer, and cannot be deleted.
Some commands have numeric options. If these commands are
invoked without a numeric option, the modem will assume option
0 (zero). For example, when the command ATB is invoked, the
modem will assume command ATB0 was intended.
All commands begin with the AT prefix, and are invoked by
pressing [Enter] (Carriage Return). The only exceptions are the
A/ command (Repeat previous command) and +++ (Exit to on-
line command mode).
·
·
The maximum command length is 40 characters. This does not
include the AT prefix, Carriage Returns, or spaces.
Note:
• All defaults are based on the &F1-Hardware Flow
Control template loaded in NVRAM.
• Defaults are marked with an asterisk (*).

Sets the number of seconds the modem will wait
before dialing. If Xn is set to X2 or X4, S6

carrier. Often used to select a longer duration when
the modem is originating an international connection.
S8
S9

Sets the duration (in seconds) for the Dial command

Determines the length of time (in tenths of a second)
the remote modem’s carrier signal must continue in
order to be recognized by the RMM.
S10
7
Sets the length of time (in tenths of a second) the
modem will wait after loss of carrier before hanging
up. Allows the modem to distinguish between a line
hit (or other momentary break) from a true disconnect
(hang up) by the remote modem.
Page 16
S-Registers
Register
Default
Function
S10
(continued)
Although it is not recommended to connect to a line
with call waiting, the S10 register can be adjusted
upward to prevent the modem from misinterpreting
the second call signal as a remote disconnect. If call
waiting is a problem, it is preferable to contact your
phone company to determine the command to
temporarily disable call waiting (typically *70W).
For example: ATDT *70W phone number.
Note: If S10 = 255, the modem will not hang up
when the carrier is lost. Dropping DTR hangs up the
modem.

and set S13 to the total of the values in the Value

* The 1.5K-byte non-ARQ buffer allows data transfer with Xmodem and Ymodem
type file transfer protocols without using flow control.
The 128 Byte option allows remote users with slower modems to prevent
transmitted data from scrolling off screen. When a remote user sends an XOFF
(Ctrl-S) to your computer and transmission stops, data in transit from your modem's
buffer does not exceed the size of the remote user's screen. This is also helpful
when a remote modem/printer application is losing characters.

Register
Default
Function
S38
0
Sets an optional delay (in seconds) before a forced
hang-up and clearing of the Transmit buffer when
DTR drops during an ARQ call. This allows time for
a remote modem to acknowledge receipt of all
transmitted data before it is disconnected.
When set at the default (0), the modem immediately
hangs up when DTR drops.
This option applies only to connections terminated by
dropping DTR. If the modem receives the ATH
command, it ignores S38 and immediately hangs up.
