YG2 Cards Details
Digital Audio
The YG2 digital audio interface is located on the console slot connector. According to the Yamaha Mini - YGDAI
standard, the YG2 card features a maximum of 16IN / 16OUT audio channels. Using the OPTOCORE CONTROL
software the card can be switch to 8 channel mode for Yamaha devices providing 8IN / 8OUT audio channels,
such as the DIO8. (Please refer to chapters “Optocore Network Setup” and “Device Compatibility”)
LC-Connectors
The dual, 1Gbps full bandwidth optical interfaces are equipped with LC-connectors, commonly used and
absolutely reliable under normal conditions. For rough applications such as touring and rental the 1U OptoCon
panel, with rugged and secure fiber optic connectors can be added to a side rack.
HA Remote
The YG2/YS2 card supports direct pick up of HA Remote signals from the console slot (HA remote signal is
available only on Slot1 in a console) e.g. provided in Yamaha CL, QL or LS9 series. If the console does not
provide the HA Remote signal on the console slot, the signal can be applied externally to the
USB/RS232/REMOTE port.
USB/RS232/REMOTE Auxiliary Port
Two RS422 digital channels with a data transfer rate of up to 1Mbps are provided via D-SUB-9 connector on the
front panel. The two channels are software patchable to any Optocore device featuring RS485/RS422 auxiliary
ports. The Yamaha HA Remote protocol can be applied from the consoles external HA Remote port and
transported to any device in the Optocore network by using the provided TRI-Y cable, enabling the connection
and remote control of Optocore or Yamaha converters directly from the console.
LAN Port
A 10/100 Mbps Fast Ethernet interface is provided via RJ45 port. All LAN ports of the Optocore devices within the
Optocore network form a virtual switch with physically distributed ports. We recommend using a standard CAT5
network cables to connect any Ethernet device such as a standard Ethernet switch for local distribution.
SUB Port
The SUB port offers the possibility to extend the number of channels transmitted to the console if connected to
the MAIN port of an YS2 card using a standard CAT5 cable.
RS232-Connection
A RS232 port is provided within the D-SUB-9 connector on the front panel. It can be used to upgrade the cards
internal logic or to connect it with the OPTOCORE CONTROL software.
USB-Connection
The D-SUB9 connector also provides an USB port. It allows you to connect with the OPTOCORE CONTROL
software as well as for firmware upgrade.
Transmission Delay
The Optocore system delay, including the matrix, is fixed to 41,6
µ
s for all channels. The transport delay per
Optocore unit (<200 ns) in the network is insignificant. The transmission delay is constant from any point to any
point. Overall delay depends on converters and fiber cable length, with ‘normal’ cable lengths of <700 m it can
also be considered as marginal.
Control
Controlling of all devices in the Optocore network including Optocore converter modules is achieved from any unit
using the OPTOCORE CONTROL software via RS232 or USB port. Both ports are available using D-SUB-9
connector on the front panel. If previously adapted by Optocore, third party protocols for card controlling can be
activated via OPTOCORE CONTROL menu
SET / SPECIAL MODE
, for example the "Yamaha mode" to control
the Optocore mice-preamps from a Yamaha-console.
Please note:
Upgrading the cards internal logic is only possible using the RS232
connection.
