Operating Manual - ne24.24M Matrix Processor

To use contact closure switching, up to eight presets (1-8) must rst be dened according to the needs of the installation.

To use the mic input “Push To Talk” feature, select the “Push To Talk Mic” checkbox in the Protea NE Software’s mic preamp

dialog box and assign it a logic input pin. The preset recall feature for that contact closure is then deactivated. Switches are

to be congured so that closing the switch contact triggers the preset recall event. It doesn’t matter if the switch is momentary

or latching, the only thing that triggers the event is the transition from open to closed for a given circuit. Closing a circuit will

automatically override any previously recalled presets. Up to eight switches can be used, with all switches sharing a common

ground connection. The number below the nine pin Euro Block contact closure connector equals the number of the preset which

will be recalled when that switch is closed. Always use the ne24.24M contact closure ground for contact closure switches. Do

not connect the ne24.24M contact closure ground to any other external grounds.

5.5 10/100 Ethernet Control Jack

Use this RJ-45 jack to connect directly to a computer or to a 10/100 Base-T ethernet network using Protea NE Software

for access to the comprehensive suite of device setup, audio controls, and monitoring functions.

5.6 0-5V Remote Level Control

Any of the inputs or outputs on the ne24.24M can have their levels remotely controlled through this simple DC control

port. Use the provided +5VDC and Ground (pins 9 and 10), along with a potentiometer, switched resistor network, or relay (for

muting), to return a DC voltage to the desired input or output control pin. Using Protea NE Software, each remote level control

pin can be assigned any combination of inputs or outputs to create up to eight remote control groups (see sec 11.1). The remote

level control can only attenuate the signal, it can not provide gain, so properly set up the gain structure within the ne24.24M

before using remote level control. +5V on any control pin has no attenuating effect, while 0V referenced to the connector ground

fully attenuates the signal. Do not connect the remote level control ground to any other external grounds.

5.7 RS-232 Dataport

The ne24.24M has two RS-232 dataports, wired in parallel, with one on the front panel and one on the back, for con-

necting to a computer for AMX, Crestron, or other third party non-ethernet controllers. Control data for the this jack uses the

RS-232 protocol, and does not support the MIDI baud rate. Supported baud rates are 9600bps and 38,400bps. Protea NE

Software will not work using RS-232, use ethernet instead.

5.8 Data In/Data Out Connection

The Data In and Out connectors are used for connecting the ne24.24M to the Ashly WR-5 programmable remote con-

troller or the RD-8C level controller.
