1 Access via Telnet
Telnet provides access to the individual receiver channel’s underlying serial control interface. The serial control
interface is not recommended for typical RDMS usage. The Telnet interface should only be accessed by advanced
users. Contact Quasonix customer support before using these options.
Note: Access to this serial control interface is provided primarily for debugging purposes. Unlike the
standard browser interface, the serial control interface within the Telnet screen is not safeguarded from
accidental or improper changes to the receiver’s configuration.
It is strongly recommended that users contact Quasonix Technical Support (Tel: [phone]) prior to using
the Terminal serial control interface.
1. In a command window, type: telnet open {IP address of the receiver to connect to} 8888.
2. Press the Enter key on the keyboard.
Figure 1: Telnet Into Terminal
The next screen (Figure 2) shows the RDMS channel subscribed to by Telnet.
Method 1-Use the Subscribed Channel
3. At this point, the user may ignore the instructions on the screen and press the Enter key again.
Figure 2: Channel Subscribed
The command prompt for the mode in the subscribed channel displays immediately, as shown in Figure 3. This is a
portal to the receiver’s serial control interface and allows the user to communicate to the individual receiver “brick”
using its basic command protocol.

Method 2-Unsubscribe and use a different channel
Look at the second Telnet screen again (Figure 4).
4. Follow the on-screen instruction and press the ` key. This is the very first key on the left side of the
keyboard under the tilde (~).

The command menu is used to unsubscribe from connections and reconnect to a specific channel. Figure 6 shows all
connections being unsubscribed.
Figure 6: RDMSIII Telnet Command Menu-Unsubscribe All Channels
In Figure 7, the user typed a 1 to subscribe (connect) to channel 1. At this point, the user may press the Enter key to
continue, as described in Method 1.

Figure 7: RDMSIII Telnet Command Menu-Subscribe to a Specific Channel
All Quasonix serial commands are alphabetic characters, followed by 0, 1, or 2 arguments. If the command is issued
with arguments, there must be a space after the alphabetic characters. The commands are not case sensitive.
All commands generate a response of one or more lines. The length of the response depends on the verbosity level.
The last response line is always the currently selected mode (PCMFM, SOQPSK, CPM, or PSK), followed by the
character “+” or “>”, depending on the version of the firmware. This prompt signifies that the RDMS™ is ready to
accept new characters.
A complete list of available serial commands can be found in section 2 or by typing HA.

Quasonix, Inc.
2 RDMS™Serial Control Protocol
The RDMS is controlled via a simple three-wire serial interface (transmit, receive, and ground). Configure your
controller’s serial port to the following settings:
•Baud rate of 115,200
•8 bits
•No parity
•1 stop bit
For setup and configuration via a standard Windows-based PC, Quasonix recommends the application called
Terminal, a flexible, full-featured control interface that is included in the RDMS Product CD. Otherwise, one can
use other terminal emulators, such as PuTTY or TeraTerm.
When power is applied to the receiver, a welcome message, shown in Figure 5, displays. After the welcome
message, the mode status displays (in this example, PCM/FM). This varies depending on the modes and versions
loaded into the RDMS. Additional status information about RDMS initialization displays last. This also varies
depending on RDMS settings and options.

The base command syntax is “a command followed by zero or more command parameters.”If the command is
issued with arguments, there must be a space after the alphabetic characters. The commands are not case sensitive.
All commands generate a response of one or more lines. The length of the response depends on the verbosity level.
The last response line is always the currently selected mode (PCM/FM, SOQPSK, CPM, or PSK), followed by the

2.1 Tier 0 (PCM/FM), Tier I (SOQPSK-TG), Tier II (Multi-h CPM) and PSK
Commands
The following table describes all receiver user commands. Listed are the command code, name, description of the
command, whether specific options must be ordered or the command is standard on all receivers, basic or advanced
command, and whether the command is restricted to specific waveform modes.
Multiple commands may be typed on a command line if they are separated by a semicolon “;”. There is a limit of
256 characters per command line, including semicolons. Commands with no parameters request status only.
Refer to command HA in section 2.1.1.25 for specific help in reading the command sets.
Refer to section 2.1.1 for additional command set detail and examples. This information is also available in the
command Help.
For example:
PCM/FM>FR 2200.5; BR 6.000; AGC
results in the following:
Frequency set to 2200.5 MHz
Bit Rate set to 6.000 Mbps
and status for all AGC parameters are displayed as:
AGC control enabled
AGC control mode RF
AGC automatic mode select enabled
AGC zero mode Auto
AGC zeroed at -110.22 dBm (13.38 dB attenuation)
AGC auto zero hold threshold 0.000 dB
AGC auto zero time constant 0.250 seconds
AGC loop total power 13.375 dB
Bulk attenuator AGC control enabled, switched out
Ctrl Y repeats the command sequence without having to retype the commands.

2.1.1 Additional Command Set Details
2.1.1.1 Commands Used with AQPSK or AUQPSK Modes
The commands detailed below generally operate on a single data stream. AQPSK and AUQPSK modulation,
however, contain two data streams that require different bit rate settings and may require other independent settings.
As a result, when using AQPSK or AUQPSK modes, some command components require a datapath parameter to
distinguish which stream is being configured. These commands include: Best Channel Selector (BCS), Clock and
Data Polarity (CP, DP), Derandomizer (DR), Data Quality (DQ), Forward Error Correction (FEC), and PCM
Decoding (PDC).
Refer to the receiver Help for the syntax specific to each command.
For example:
BCS in AQPSK mode
Displays and controls best channel selector settings
BCS [<d><e>] –Sets best channel selection enable for data <d> to <e>
where:
<d> - Datapath component
A –Data A
B –Data B
<e> - Enable
0 –Disabled
1 –Enabled
All of the commands follow a similar pattern, however, not all components of a particular command contain the
datapath parameter. In the following BCS example, the BCS Source controls the enables for both BCS channels:
BCS [S<s><e>] - Sets best channel selector source <s> enable to <e>
where:
<s> Sources
CH0 –Channel 0

Technical Guide: RDMS Telnet and Serial Control
15
Quasonix, Inc.
CH1 –Channel 1
INT –Internal
where:
<e> Enable
0 –Disabled
1 –Enabled
BCS NOT in AQPSK mode
Displays and controls best channel selector settings
BCS [<e>] –Sets best channel selection enable for data <e>
where:
<e> - Enable
0 –Disabled
1 –Enabled
2.1.1.2 Antenna Control Unit - ACU
