Controls and Jumpers
Jumpers
Jumper Configuration
The line impedance of the tone remote is configured using jumpers. Remotes are
configured for either a low impedance (600
) if they terminate the transmission line, or a
high impedance (6000
) if they do not.
covers the configuration of the Model 280
covers the configuration of all four line inputs on the Model 284.
JP1
2-wire RX
Termination (1)
Selects whether the unit provides a high or low impedance termination to
Line 1. The default position is “A”, which terminates the line at 600
. In
multiple remote systems, all the remotes should be in the “B” position
(6000
), except for the farthest remote that terminates the line in 600
.
JP2
2-wire RX
Termination (2)
This jumper is used in the Model 284 to select a high or low impedance
termination to Line 2. In multiple remote systems, all the remotes should
be in the “B” position (6000
), except for the farthest remote that
terminates the line in 600
. Not used in the Model 280 tone remote.
JP3
4-wire RX
Termination (2)
This jumper is used in the Model 284 to select a high or low impedance
termination to Line 2. In multiple remote systems, all the remotes should
be in the “B” position (6000
), except for the farthest remote that
terminates the line in 600
. Not used in the Model 280 tone remote.
JP4
4-wire RX
Termination (1)
Selects whether the unit provides a high or low impedance termination to
Line 1. The default position is “A”, which terminates the line at 600
. In
multiple remote systems, all the remotes should be in the “B” position
(6000
), except for the farthest remote that terminates the line in 600
.
JP5
There is no JP5 in the Digital Tone Remotes.
JP6
External Audio
Enable
Enables or Disables the external mic input. Default position is disabled,
position “A”.
JP7
2-wire RX
Termination (4)
This jumper is used in the Model 284 to select a high or low impedance
termination to Line 4. In multiple remote systems, all the remotes should
be in the “B” position (6000
), except for the farthest remote that
terminates the line in 600
. Not used in the Model 280 tone remote.
JP8
4-wire RX
Termination (3)
This jumper is used in the Model 284 to select a high or low impedance
termination to Line 3. In multiple remote systems, all the remotes should
be in the “B” position (6000
), except for the farthest remote that
terminates the line in 600
. Not used in the Model 280 tone remote.
JP9
4-wire RX
Termination (4)
This jumper is used in the Model 284 to select a high or low impedance
termination to Line 4. In multiple remote systems, all the remotes should
be in the “B” position (6000
), except for the farthest remote that
terminates the line in 600
. Not used in the Model 280 tone remote.
JP10
2-wire RX
Termination (3)
This jumper is used in the Model 284 to select a high or low impedance
termination to Line 3. In multiple remote systems, all the remotes should
be in the “B” position (6000
), except for the farthest remote that
terminates the line in 600
. Not used in the Model 280 tone remote.
