The Blackrock processor is supplied with four MADI ports as standard but may be expanded to provide eight ports (as
shown opposite). The RIO unit is always equipped with four ports.
Connections between the Blackrock and RIO units are made using standard duplex LC – LC fibre cable assemblies. Default
multiplexers are multimode standard. Suitable fibre cables are widely available from cable suppliers.
Singlemode fibre multiplexers can be specified for the Blackrock and RIO as a cost option. These will require matching
singlemode connectors and cable assemblies. Refer to page 2-9 for additional information..
RIOs that feature a blacklight interface can support up to 256 channels per fibre link. Note that Blacklight links function
as a main-plus-redundant pair – the second fibre acts as a backup to the first link.
MADI equipped RIOs provide 62 channels on the first fibre link and 64 channels for each subsequent lead. MADI
interfaces may also be configured to operate as redundant pairs. The maximum channel count for MADI systems that
require fibre redundancy is therefore 126 channels with a single processor and 62 channels with redundant processors.
Blackrock-to-RIO MADI interface ports operate as either four-individual OR two-redundant-pairs. It is not possible to operate
one pair and two individual ports.
Up to four RIO units can be connected to a Blackrock processor.

gP io

The RIO Interface card is equipped with 24 circuits of GPI I/O. Inputs are fitted with 25-pin D-type male connectors.
Outputs are 25-pin D-type female connectors. Mating connector kits are available to order. Both the input and the output
circuits are fully isolated from the RIO electronics.

uTPuTS
All output switch closures are via DIL relay – the contact rating is 100Vdc, 125Vac, 100mA max. Do not use these
outputs to directly switch capacitive or reactive loads; always use a separate external relay with suitable contact rating.

NPuTS
Inputs are is triggered by applying an AC or DC voltage of between 4V and 30V between each pair of contacts. The current
drawn is approximately 10mA. A voltage suitable for the input trigger is available on the output connectors and a 0V
reference is provided on the input connectors.
The input and output signals can be either latching or momentary; this is individually assigned in software using the touch
screen. When set to momentary, the input signal trigger duration must be greater than 50mS.
When used for discrete track arming with associated tally, the tally must return to the same number input as the arming
output signal, (ie. the tally for GPI Out 1 will be on GPI In 1).

The 'Sync' connector fitted to the front of the RIO interface card provides an output of Wordclock at the system's clock
rate.

The Ethernet connector on the RIO interface card is non functional so must not be connected.
