[. . . ] When an analog I/O module is the Control Master, there is no other analog module that can be used as a clock source in an all-analog network. When a 6416Y2 console interface card is part of an audio network, the 6416Y2 can be used as a Clock Master for the network; it coNtrol MAster must also be the network's Control Master to have control over clock functions. When a 6416Y2 card is the Clock Master, its clock is derived from the Yamaha host device. (Multiple 6416Y2 cards can be used in a Yamaha host device, but only one can be set to be Control Master and Clock Master. ) External clock sources on digital modules can include: · The internal clock reference from the Yamaha device · Word Clock received via the external Word Clock inputs on a Yamaha device · Word Clock via the dedicated BNC Word Clock jack on a Pro64 digital I/O device, such as the 6416dio Digital I/O Module · AES3 (AES/EBU) from an AES3 digital stream on a Pro64 digital I/O module Clock Errors If a clock error occurs, the Clock Master LED will blink indicating that an error has occurred. Common causes for a clock error include: · Attempting to change the sample rate on a device other than the Clock Master · Attempting to change the clock source when the network is password protected · Removing or changing external clock sources on a digital I/O module · Incorrect configuration of an external clock source on a digital I/O module Network Sample Rate When an analog device is the Control Master, the Control Master is automatically designated as the Clock Master. It will remain the Clock Master until a different analog module is made the Control Master or until a digital module such as the 6416Y2 card is added to the network and is assigned to be the Control Master and Clock Master. The network's internal master clock is derived from the sample rate currently in use. The sample rate also affects the total number of available A-Net Slots available for use in the network. The Clock Master LED on the 6416Y2 card (labeled CLK) will light automatically when its host is powered on if the 6416Y2 card is Control Master and Clock Master for the Pro64 network. When a 6416Y2 card is Control Master, the network clock is derived from the Yamaha host coNtrol MAster device. That clock reference can be the Yamaha host's internal clock or an external clock to which the Yamaha host device is synced. Changes to the host's sample rate will affect available A-Net Slots. The Sample Rate section of a rack-mounted hardware I/O module's front-panel interface (e. g. , 6416i Input Module) includes a group of LED indicators for displaying the current network sample rate. However, the current sample rate information will be sent to all Pro64 network devices when a 6416Y2 card is Control Master/Clock Master. The sample rate display on Pro64 I/O modules will display the current networkwide sample rate when a 6416Y2 A-Net Interface Card is the Clock Master, receiving its clock from the Yamaha host device. The current sample rate for the network will be displayed on all I/O modules in the network, and will update to reflect any changes made from the Yamaha host (such as changing the sample rate from 48kHz to 96kHz). Only one sample rate can be used at a time in a Pro64 network. Changing the Sample Rate Changing the sample rate when a 6416Y2 A-Net Interface Card is the Clock Master is done from within the Yamaha user interface. Changing the sample rate will affect the number of available A-Net Slots when the sample rate changes from the 1x range (44. 1/48kHz), to the 2x range (88. 2/96kHz), or vice versa. Note that only sample rates up to 96kHz are supported by Yamaha digital devices. Auto/Manual Mode Selection The Control Master can be used to set the current network mode to Auto or Manual. As with the system-wide sample rate, the network mode is also a global setting. The 6416Y2 is configured using DIP switches, with DIP Switch Block 9 (SW9) on the circuit board used to set the network mode. This means 0 coNtrol MAster that changes to the Pro64 network mode require the host Yamaha device to be powered down so that the 6416Y2 card can be removed. Changing the Network Mode To change the network mode from a 6416Y2 card that is the network Control Master, move switch 1 in Switch Block SW9 to the desired position, down for Auto Mode, or up for Manual Mode. The Control Master will update the display on all modules in the network to reflect the mode change once the network is restarted. Managed Mode Managed Mode requires the use of a computer with the Pro64 network for tasks such as software/firmware updates, system monitoring, control, and editing. The Control Master is the only module that can allow the network to enter Managed Mode. [. . . ] A true null modem cable is required for the interaction of the RS-422 termination on pin 4 of the connector with the RS-232 signals. On an RS-232 connector, pins 3, 4, and 7 are outputs; pins 1, 2, 6, and 8 are inputs. In a standard null modem cable, pin 4 at one end of the cable 4 sPecificAtioNs will drive pins 1 and 6 at the other end. With a 100 ohm resistor across pins 3 and 4 on the Aviom DB9 connector, pin 3 (RS-232 ­Tx) will drive pins 1 and 6 at the other end of the cable through the 100 ohm resistor. [. . . ]
