IRIS-Net
Element Description
MAX. OUTPUT Set the maximum output power of the channel.
POWER
MIN. IMPEDANCE Set the minimum impedance connected to the channel.
50 HZ LOW CUT Activates the 50 Hz Low Cut filter.
VLD ACTIVE Activates the VLD mode of the channel. This checkbox has an effect only if the amplifier output
channel is operated in output mode 2 Ohm/ VLD. In the output modes 4 Ohm, 70 V or 100 V the
setting of the checkbox has no effect on the output channel.
Firmware Upgrade
The firmware of RCM-810 remote amps is stored in a FLASH-memory chip. This technology has been chosen to be able
to provide the users with new software without the hassle of physically exchanging memory chips inside of a remote
amplifier. Using IRIS-Net, upgrading the firmware is possible via the CAN Remote Control Interface. In this way you can
install new firmware and future software extensions to always keep your Remote Amplifier System up-to-date.
The RCM-810 firmware is divided into a part for basic amplifier functions (e.g. power on/off, CAN communication) and
a part for extended functions (e.g. signal processing). Even if the firmware update procedure does not finish
successfully, basic amplifier functions stay functional and the update procedure can be repeated.
Caution!
Upgrading the firmware is always a very sensible procedure – comparable to updating the OS in
!
the FLASH-memory of a PC. Therefore, obeying the following precautions and instructions is
absolutely mandatory:
Consequences
1. Simultaneously upgrading the firmware of more than four remote amplifiers is not recommended.
2. Only connect the remote amps to the CAN Remote Control network that are to be updated. Disconnect any other
remote amps from the CAN-bus during the upgrade. Make sure to carefully mind all regulations for the CAN
Remote Control network, especially the 120 Ω termination at both ends of the bus.
