DIP Switch Settings for Networked Devices
Assign each Shure Link device a unique Device ID Number, using DIP
Switches 1-4, as shown in Figure FIGURE 13. Refer to Table 2 for De-
vice ID settings.
IMPORTANT: Each Shure Link device MUST have a unique Device ID
number.

CONTROL PIN CONNECTIONS
The control pins on the back of the DFR22 connect to switches, potentiometers, and controller hardware. The Control Input pins can be used to
change presets, adjust gain, and mute channels.
NOTE:
Use the DFR22 software to configure the control pins so that they match the attached control hardware. You can also use the software to
assign minimum and maximum gain values for each control, as well as the gain increment for up/down volume control buttons. Refer to the
Control
Pin
section of the Online Help or to the Online User Guide.
Determining Control Pin Allocations
When allocating control pins, you should first determine which pins are
to be used for
preset control
. Any remaining pins can then be used to
adjust gain or to mute channels. The number of pins needed for preset
control depends on the type of control hardware used, as well as the
number of presets.
The following methods can be used to allocate control pins:
•
One-to-One:
Use one pin for each preset, starting at Pin 1, and
proceeding toward the right. You MUST use consecutive pins.
Connect momentary or latching switches.
•
Shure DRS10 Switch:
Use Pin 1 for up to 10 presets.
•
Custom Switch:
Use Pin 1 for up to 10 presets.
•
Binary:
Use the pin numbers listed in Table 3. Connect latching
switches.
Table 3. BINARY CONTROL PIN ALLOCATION
Preset Control Connections
Various types of control hardware can be connected to the Control In-
put pins, as shown in Figure . When properly configured, the DFR22
changes to the appropriate preset in response to the switch. Resistor
values for custom switches and the Shure DRS10 are listed in Table 4.
NOTE:
The total resistance of the cable run, from the switch to the
DFR22, should be less than 100 ohms. Two-conductor, unshielded cable,
such as a Belden 8442, is recommended.
