(Additional) Installation Manual
SYSTEMS REMOTE MICROPHONE WITH
MONITORING OF MICROPHONE CAPSULE
RM-200MS
This manual contains the special installation information for the RM-200MS. The RM-200M instruction
manual contains all instructions of setting and operation, so both manuals are required to operate the
RM-200MS.
Please follow the instructions in this manual to obtain the optimum results from this unit.
We also recommend that you keep this manual handy for future reference.
■
IMPORTANT NOTE
DIFFERENT CONNECTION !
The connection of the RM-200MS differs from the RM-200M connection!
Do not connect the RM 200MS with the standard RM-200M using the RJ45 link
connectors! This will cause either no microphone capsule failure indication or
may result in an insufficient power supply to the remote microphones.
■
DESCRIPTION
The microphone capsule of the RM-200MS is monitored on failure, and a failure control signal is
provided to indicate a failure on the microphone capsule. This function is required for the remote
microphone (for emergency purposes) to comply with the EN 60849.
In case of a microphone capsule failure, the failure LED on the VM-2000 and RM-200M(S) will
illuminate. It is also possible to control an extra LED for a separate failure indication.
■
DIFFERENCE TO THE RM-200M
The failure control signal of the RM-200MS is sent to the VM-2000 using a pair of connectors of the
RJ45 port. On the standard remote microphone RM-200M, this pair is used for the DC power supply,
therefore the RM-200MS must not be linked with the standard RM-200M using the link connectors.
■
CONNECTION OF THE RM-200MS TO THE VM-2000
The wire connected to the pins 1 and 2 of the
RJ45 connector are used for the failure
control signal instead of power supply. So
these wires must be disconnected from the
VM-2000. Wire 1 (once connected to pin 1 of
the RJ45 connector) must be connected to pin
15 of the CONTROL I/O connector, and wire
2 to pin 16.
At the location of the VM-2000, the control
signal can be separated from the incoming
cable by using the VM-RJA board, and the
RJ45 connection to the VM-2000 can be done by a ready-made cable. The separated failure control
signal will be connected to the external failure input on the I/O CONTROL connector. Please refer to
the next page.
