CHAPTER 1 - GENERALINFORMATION
1.1 GENERAL
NV3128 RS-422A Machine-Control Data Switch
1.2 ARCHITECTURE BACKGROUND
NV3128 RS-422A Machine-Control Data Switch
Because commands are broadcast on one balanced pair and responses received on another, the systems crosspoint count, wiring density and complexity are inherently double that of a video or audio router. Fig. 1.2 shows the two- level connection required to implement a route through a conventional data switch. To pass through the switch, the connection must be separated into two components the command, which travels from source to destination, and the response, which returns through the switch from destination to source. Cables are split such that transmitting pins from both machines are hooked to switch input blocks, and receivers to output blocks. Additionally, the router-control system must be highly specialized, for it now must address two connections with every connect command it issues

To further complicate matters, the sense of transmit and receive connections in many modern machines is switchable. That is, internal circuitry within the machine reassigns the interface pin assignments to allow it to operate in either controlled or controlling mode. Fig. 1.3 illustrates the physical pin swapping within each of two directly connected devices. On most units the changeover is a physical switch, but on some, such as the Sony D1 VTR, the pin flip is under software control. In either case, the traditional routing switch cannot adapt to a reversal of data direction, and thus severely compromises a systems flexibility. Referring again to Fig. 2, note that the physical connection fixes the operating mode - controlled or controlling - of the device. If pin pair 3/8 from a machine is connected to a router input, then that machine is a controlling device from now until someone gets out a crimping tool and rewires the connection
