Introduction: The VMIVME-6015* Serial Input/Output (SIO) is a Self-Test The MK68564 SIO chip is designed with internal self- four-channel multifunctional peripheral interface board, test logic that supports a loop test on each SIO channel. When designed to satisfy a wide variety of serial data the loop mode bit is set in the command register, the receiver communications requirements in VMEbus systems. The basic shift clock input pin (RxC) and the receiver data input pin (RxD) function of the VMIVME-6015 is a serial-to-parallel, parallel-to- are electrically disconnected from the internal logic. The serial controller; however, it is software configurable so that its transmit data output pin (TxD) is connected to the internal “characteristics” may be optimized for any given serial data receiver data logic, and the transmit shift clock pin (TxC) is connected to the internal receiver shift clock logic. All other communications application. features of the SIO are unaffected. The VMIVME-6015 is capable of handling asynchronous RS485 Token Passing Network: GE's Model VMIVME-6015 SIO protocols, synchronous byte-oriented protocols (such as IBM interface provides an easy connection to the new RS485 BiSync), and synchronous bit-oriented protocols (such as HDLC interface standard. RS485 is an upgraded version of the earlier and IBM SDLC). This SIO Controller can also be used to support RS422 standard for balanced voltage digital interface circuits. virtually any serial protocol for applications other than data Up to 32 RS485 devices can be multidropped onto a single low- communications (cassette or floppy disk interface, for example). cost 24-gauge twisted-pair cable, forming a half-duplex network. The RS485 transmitter in the VMIVME-6015 is The VMIVME-6015 can generate and check CRC codes in any controlled via the RS232 request-to-send signal. The RS485 synchronous mode and may be programmed to check data interface is typically capable of 0 to 100 Kbaud at distances up integrity in various modes. The controller also has facilities for to 4,000 feet. modem controls, and in applications where these controls are A network of RS485 devices would normally be implemented in not needed the modem controls may be used for a token bus topology. All devices would be wired in line, one general-purpose I/O. after another, forming a single main bus.

All the RS232 devices connected to the bus via a self-test capability. When the loop mode bit is set in the VMIVME-6015 need to share some common software in order to determine which device has possession of the token, and to command register, the loop mode is activated to support control their request-to-send signals.
