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.

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.

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 online 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 (*).

Counts and stores the number of rings from an incoming call. Register S0 must be greater than 0.
Stores the ASCII decimal code for the escape code character. The default character is +. A value of 128-

Stores the ASCII code for the Carriage Return character. Valid range is 0-127.
Stores the ASCII decimal code for the Line Feed character. Valid range is 0-127.
Stores the ASCII decimal code for the Backspace character. A value of 128-255 disables the Backspace key's delete function.
Sets the number of seconds the modem will wait before dialing. If Xn is set to X2 or X4, S6 determines the timeout length when no dial tone is detected.
Sets the number of seconds the modem will wait for a carrier. Often used to select a longer duration when the modem is originating an international connection.
Sets the duration (in seconds) for the Dial command pause option (,).
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.
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.

S10
(continued)
Default Function
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.

Sets the duration (in fiftieths of a second) of the guard time for the escape code sequence (+++).
Bit-mapped register. Select the bit(s) you want on 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.

S38
S-Registers
Default Function
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.
