13. REMOTE CONTROL OPERATION

13.1. Overview

In many circumstances you will adjust and control your Sabine
SWM7000 wireless microphone system using the front panel controls,
as outlined in previous sections of this operating guide. In circum­stances where an enhanced level of control over a single receiver is
desired, or to enable simultaneous computer-based control of multiple
receivers, you will need to install (on either a laptop or desktop com­puter) the free Sabine SWM Remote Control Software Software included
with your system. Only receivers may be remotely controlled; handheld
and belt pack transmitters cannot be remotely controlled.

For online instructions for any function in the software, you may also
refer to the Help menu.

13.1.1. Single Receiver vs. Multiple Receiver
Remote Control

All SWM7000 series receivers have an RS-232 jack on the back for
serial connection to your computer. Thus, any single receiver can be
controlled remotely.
puter is possible only for ND-series (SW51ND-R and SW52ND-R) re­ceivers. These units have additional RS-485 network connections (RJ­45 jacks) for daisy-chain connection from one receiver to the next. Up
to 35 receivers (70 transmission channels if all receivers are 2-channel)
may be connected in this network, all under the control of a single
computer. Single and dual channel receivers can be mixed in the same
network. The first receiver in such a network can be connected to the
computer via an RS-232 or RS-485 serial cable; the remaining units will
then be connected via RS-485.

It is not possible to upgrade/retrofit a standard receiver to make it an
ND-series unit.

13.1.2 Features & Controls Added by SWM
Remote Software

All front panel controls and displays are duplicated in the software. In
addition, a deeper level of software control over receiver operation is
enabled. These new controls are complete and independent for each
transmission/reception channel, meaning there are two sets of con­trols for dual channel receivers. These controls and displays include:

• Parametric filter access and control. FBX filters can be changed

to parametric filters, and their width, depth, and frequency can be
adjusted. Changes can be made at any time, both before and after
FBX filters have been set. Parametric and FBX filters can be mixed
in any combination, totaling 12 for each receiver channel.

• Adjustable FBX parameter control. Maximum depth of FBX fil-

ters can be adjusted globally; filter width can be adjusted globally
or individually. Two controls,

Sensitivity and Persistence, can be
tweaked to tailor the operation of automatic FBX filter placement to
match the audio program. Proper settings will optimize the bal­ance between false filtering and delayed response to feedback (the
factory default settings should operate excellently in the vast ma­jority of conditions and may never need to be changed).

• Control over balance of FBX Fixed and Dynamic filters. Any

FBX filter can be set to be either fixed or dynamic.

Multiple Systems Operation

• Adjustable high and low cut filters. High Cut Filter, user-control-

lable between 3 KHz and 20 KHz; 12dB/octave roll-off

• Additional compressor controls. Aside from adjustments for

ratio, threshold, and attack (which duplicate front panel controls),
the Remote Software provides control of compressor release time
and knee. The effect of compression on the output signal as a
function of input signal strength and parameter settings is displayed
in Sabine’s unique dynamic ColorComp graph, in addition to the
traditional opposing-meter indicators.

• RF Scan and Report, which measures strength for each of the 70

transmission channels, and displays a hierarchical ordering of the
clearest, strongest channels to use during system setup and op­eration. You can print a copy of the scan results.

• Additional memory options. In addition to saving presets in re-

ceiver memory, channel configuration settings can be saved to and
recalled from disc or hard drive. All parameter settings made with
the remote control, including adjustments that are not accessible
from front panel controls (e.g., compressor knee and release), are
saved with presets. All software settings stored for each of the 15
presets, including settings not accessible from the front panel, will
be loaded whether presets are recalled by remote control or from
the front panel. Note that all settings made in Off-line/Edit mode
can be saved and applied in online operation..

• Ability to print a report of all parameter settings, creating hard

copy documentation.

• A receiver channel output mute button.

• The ability to custom name each RF channel and receiver. This

name will be displayed in both software operation, and on the re­ceiver front panel.

• Display of important transmitter status information. In addi-

tion to duplicating the battery charge status, battery warning mes­sage, and transmitter on/off/mute status from the front panel dis­play, the Remote Software displays the type of battery in use, the
number of hours the battery has been in use, the frequency mid­point (in GHz) of the transmission channel chosen, the transmitter
pad and low cut filter settings, and a warning indication in the case
of low RF signal strength. For handheld transmitters, the software
display also shows the type of mic capsule in use.

• Improved and expanded operational displays. In addition to

organizing all front panel displays on a single computer screen, the
Remote Software also displays the exact frequency, width, and
depth of FBX filters. The frequency response curve resulting from
combined filter settings (including FBX, parametric, and high and
low cut) is graphically displayed in the software. Frequency re­sponse changes imposed by choosing various microphone models
are also shown.

• Customizable front panel lock settings. Software control allows

you to program selective access to front panel controls to be made
available once the Remote Control is disconnected. Customizable
front panel lock settings are saved and recalled as part of each
receiver’s settings. All software-only accessible settings are saved
with presets. Careful programming enables some powerful opera­tional features — for example, locking Program Save but enabling
other front panel controls (including Program Load) will let front

panel users update settings temporarily, yet reload the original set­tings at the push of a button. Such a temporary adjustment would
not permanently alter a setup designed to work in most situations,
but would allow tweaking to address unusual situations.

13.1.3. Multiple Unit Control by Remote Software

The true extent of the power of the SWM Remote Software is realized
when it is used to control multiple wireless receivers. When ND-series
receivers are connected in a network, the additional controls offered by
the Remote Software over the entire system include:

• Simultaneous multiple channel/system monitoring. The Re-

mote Software “All Channel View” (figure 13g) shows all important
status conditions for up to 50 transmission channels. Color-coded
warnings and alerts draw attention to potential problems.

• Detailed, quick access to a single set of controls. The “Com-

mand View” (figure 13c) displays comprehensive information about
a single selected RF channel, and easy adjustment of all its con­trols. Command View channel is selected by clicking the appropri­ate All Channel View button. (NOTE: Each channel display in the
All Channel View also allows quick access to parameter adjust­ments, by using the right mouse button to popup a parameter con­trol menu.)

• Quick, interactive control of wireless network channels. All or

selected parameter settings for a given channel can be copied to
one or more additional channels, using the Copy Parameters op­tion.

13.2. Software Installation

13.2.1. System Requirements/Recommendations

• PC computer equipped with Pentium processor 100 MHz or faster

• Hard disc with at least 10 MB of available space for program files.

• Windows 95 or higher.

• SVGA or greater resolution graphic card and monitor.

• Recommended minimum monitor resolution: 1024 x 768 pixels (or

800 x 600 pixels for 15 inch monitors). Select “small fonts” and 16
bit color as defaults for monitor display.

• One COM port for a serial connection, with a 16550 or faster COM

chip.

13.2.2. Connections

There are two types of connections that are used in a remote controlled
Sabine SWM7000 system:

• For connecting from the serial port on your computer to either a
single receiver, or to the first unit in a multiple receiver system, use
a cable with standard 9-pin D-connectors (male on one end, female
on the other). This plugs into the RS-232 jack on the receiver rear
panel. One connection is all that is necessary even if the receiver
is a 2-channel unit.

NOTE: for connections using a USB connector, a USB to RS-232
adaptor is necessary (see Appendix).

• For connecting to additional (ND-series only) receivers (beyond the
first unit) in a multiple receiver system, use cable adhering to RS-
