Rane NM 84, Operator'S Manual

Manual-6

Memory Edit page

The Memory Edit page stores and recalls the 16 NM 84

Memories. Memory Recall Port Transmit (MRP Tx) and MRP

Receive (MRP Rx) are also set in this page.

Conceptually, the NM 84 contains 17 Memories; Memory

zero contains the current settings which are always displayed

on the LCD screen. Therefore, all changes made from the

front panel alter the current settings – Memory zero. Once the

desired settings are reached using the Edit pages, Memory

zero (the current settings) can be stored into one of the 16

Memory locations. Additionally, recalling one of the 16 stored

Memories places that Memory’s contents into Memory zero

for display, viewing, and further editing if needed.

The number of the most recently recalled Memory, 1

through 16, is displayed on the top left of the Mem LCD page.

An asterisk (*) appears to the right of this Memory number

when the current settings no longer matched the displayed

Memory’s contents. This indicates a change to the NM 84

settings has been made since the last Memory was recalled.

To store the current settings, move the cursor under Store,

use the DATA wheel to display the Memory number to store

the currents settings into, then press the EXE button.

To recall, move the cursor under Recall, use the DATA

wheel to display the Memory number to recall from, then

press the EXE button which overwrites the current settings.

The NM 84 provides up to 16 MRP (Memory) data

transport channels which are asynchronously transported over

the CobraNet network to other NM devices which are set to

“listen” to the corresponding MRP channels. The MRP Tx

(MRP Transmit) parameter can be set to one of the 16 MRP

channels or Off. The Off setting – you guessed it – turns off

MRP transmission. The numeric settings – integers 1 through

16 – tell the NM 84 to Transmit its current MRP contact

closure status over the network to other NM devices that are

set to receive the corresponding MRP channel. This allows

other Rane NM devices to use remotely located NM device’s

MRP switch states to change Memories.

The MRP Rx (MRP Receive) parameter can be set to

Local, Off or integers 1 through 16. The Local setting tells

the NM 84 to scan its own rear panel Memory Recall Port for

switch closures. Off turns off the MRP completely and 1

through 16 sets the desired MRP channel to “receive from” or

“listen to.”

The following parameters are stored in each Memory:

 All Mic In settings: Mode, Mute, Trm, Gain, 48V, Flt, Lim

 All Monitor Out settings: Source, Bndl/Mic, AudCh

 All Serial, RS-232, settings: Baud, 232 Rx, 232 Tx

Therefore, parameters found in the NetTx, Mem and

Config edit pages are not stored in Memories. The intent of

disallowing Memories to alter the Network Transmit settings,

for example, is to keep the familiarity of a radio broadcasting

paradigm relevant to CobraNet network Bundles. Thus,

sticking to always transmitting audio over the same Bundles

while using Memories to re-route to the desired channels,

helps make things more easily managed. In other words,

always transmit on the same Bundles (i.e., fixed radio station

transmission) but “tune in” to the desired Bundle and Audio

Channel to receive (Monitor) the audio needed.

Serial Edit page

The Serial Edit page configures the RS-232 port. The

Baud parameter must be set to the desired baud rate for the

device used with the RS-232 port. Typical choices up to

38,400 baud are found. See the complete list below.

The NM 84 provides up to 255 serial data channels which

are asynchronously transported over the CobraNet network to

other NM devices set to receive and transmit over correspond-

ing serial channels. The 232 Tx and 232 Rx parameters set

these respective transmit and receive serial channels for

transport of the RS-232 port’s data. Be certain to use one

channel for transmit such as 1, and a different channel to

receive, such as 2. We know that you know that 1 is different

than 2, but this is of course necessary, since RS-232 requires a

different transmit and receive pair and therefore independent

channels.

Another important thing to remember as far as the 232

port’s physical connections go, be sure you review the

required connector sex, male or female, when transporting

232 around. All NM devices contain a female RS-232 (DB-9)

connection on the rear.

For example, when transporting Rane’s RW 232 protocol

from a computer to an NM 84, over the network to another

NM device, the cabling should be as follows:

The end of the cable at the computer connection will be

female – since the DB-9 on a computer’s COM ports are male.

The other end of the cable will be male so one can connect it

at the initial NM 84 device. At the second NM device, the rear

panel DB-9 is female, thus requiring a male on the end of the

second cable. The DB-9 Input on RW 232 devices is a female.

Therefore, a male-to-male gender bender is required on the

RW 232 Input side of the second cable to permit using a

standard serial cable.
