Configuration Switch S6: Serial Port 4 Clock Select (S6-1, S6-2)

Serial port 4 can be configured to use clock signals provided by the RTXC4 and TRXC4 signal lines. Switch segments S6-1 and S6-2 on the MVME197LE configures serial port 4 to drive or receive TRXC4 and RTXC4, respectively. Factory configuration is with serial port 4 set to receive both signals (open). The remaining configuration of the clock lines is accomplished by using the Serial Port 4 Clock Configuration Select header on the MVME712M transition module. Refer to the MVME712M Transition Module and P2 Adapter Board User’s Manual for configuration of that header.

Connectors

The MVME197LE has two 64-position DIN connectors: P1 and P2. Connector P1 rows A, B, C, and connector P2 row B provide the VMEbus interconnection. Connector P2 rows A and C provide the interconnect to the SCSI bus, the serial ports, the Ethernet interface, and the Centronics printer. There is a 249-pin mezzanine connector (J2) with the MC88110 bus interface. This mezzanine connector is for MVME197LE module expansion. There is also a 20-pin general purpose connector (J1) which provides the interconnect to the LEDs and the reset and abort signals. Refer to the SIMVME197LE Single Board Computer Support Information manual for detailed signal descriptions.

Installation Instructions

The following sections discuss installation of the MVME197LE into a VME chassis, and system considerations. Ensure that the BOOT ROM device is installed. Ensure that all switches are configured as desired.
