REFERENCE MONITORS RM-2S4 & RM-2S10
REFERENCE MONITORS RM-2S4 & RM-2S10
1
The AES/EBU Lock output is a real-time (non-latching) status output which becomes active
if a valid AES/EBU signal is detected on the currently selected Source input. By default, the
open-collector output is low (conducting) when a valid AES signal is detected, but this
behaviour may be reversed using the serial remote control LCK: command.
The active-low control inputs all have internal pull-ups. Equipment driving these inputs
need sink only 1mA and block 5V.
The MUTE input mutes the loudspeakers and headphones while held low. The front panel
CUT L and CUT R buttons illuminate to indicate that MUTE is asserted.
The DIM input reduces the loudspeaker/headphone level by 10dB while held low (for
example, whilst an external talkback system is active). The front panel DIM button
illuminates to indicate that DIM is asserted.
Asserting the Alarm Reset input by pulling it low resets any active Alarm outputs to their
untriggered states and allows them to monitor for new alarm conditions.
RS232 Remote Control
A 9-way female D-type connector carries a standard RS232 interface via which advanced
conguration options may be set and many functions may be remotely controlled. The pin
assignations are as follows:
Pin 2: Data transmit
Pin 3: Data receive
Pin 5: Ground
All other pins are unused.
The RM-2S4 and RM-2S10 will interface directly with personal computer serial ports at
standard RS232 signal levels using a straight-through cable. The data format is 19200 baud
with 8 data bits, even parity and 1 stop bit. XON/XOFF ow control is used when necessary.
Sonifex SCi software, when installed on a suitable PC, provides straightforward graphical
access to all remote control and conguration options via both RS232 and USB interfaces.
Alternatively, commands may be issued from any text-based terminal program
(e.g. Hyperterminal) or custom software may be developed for specic requirements.
