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 13. Refer to Table 2 for De- vice ID settings.

IMPORTANT: Each Shure Link device MUST have a unique Device ID number.

*Default setting.

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 need- ed 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:

SOne-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.

SShure DRS10 Switch: Use Pin 1 for up to 10 presets.

SCustom Switch: Use Pin 1 for up to 10 presets.

SBinary: Use the pin numbers listed in Table 3. Connect latch- ing switches.

Preset Control Connections

Various types of control hardware can be connected to the Control Input pins, as shown in Figure 14. 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.

PRESET	RESISTOR VALUE
1	Ω	–	∞ Ω
	97 k
2	44–60 kΩ
3	26–32 kΩ
4	17–20 kΩ
5	11.3–13.6 kΩ
6	7.8–9.3 kΩ
7	5.2–6.3 kΩ
8	3.3–4.1 kΩ
9	1.9–2.5 kΩ
10	0.63–1.1 kΩ
