TRICONEX 4352AN Redundant output card

System Controller Select Header (J1) The MVME162 is factory-configured as a VMEbus system controller (i.e., a jumper is installed across pins 1 and 2 of header J1). Remove the J1 jumper if the MVME162 is not to be the system controller. Note that when the MVME162 is functioning as system controller, the SCON LED is turned on. Note For MVME162s without the optional VMEbus interface (i.e., no VMEchip2), the jumper may be installed or removed without affecting normal operation.

The MVME162 is shipped from the factory with the SERIAL PORT 1/CONSOLE header configured for asynchronous communications (i.e., jumpers removed). To select synchronous communications for the SERIAL PORT 1/CONSOLE connection, install jumpers across pins 1 and 2 and pins 3 and 4.

Clock Select Header (J12) for Serial Port 2 

The MVME162 is shipped from the factory with the SERIAL PORT 2 header configured for asynchronous communications (i.e., jumpers removed). To select synchronous communications for the SERIAL PORT 2 connection, install jumpers across pins 1 and 2 and pins 3 and 4.The MVME162 is factory-configured to use VMEbus +5V standby power as a backup power source for the SRAM (i.e., jumpers are installed across pins 1 and 3 and 2 and 4). To select the onboard battery as the backup power source, install the jumpers across pins 3 and 5 and 4 and 6. Note For MVME162s without the optional VMEbus interface (i.e., without the VMEchip2 ASIC), you must select the onboard battery as the backup power source. Caution Removing all jumpers may temporarily disable the SRAM. Do not remove all jumpers from J20, except for storage.

EPROM Size Select Header (J21) 

The MVME162 is factory-configured for a 4Mbit EPROM (i.e., a jumper is installed across pins 2 and 3). This is the only size currently available; if a larger EPROM becomes available, this jumper will allow it to be selected.Header J22 provides eight readable jumpers. These jumpers can be read as a register (at $FFF4202D) in the MCchip LCSR (local control/status register). The bit values are read as a zero when the jumper is installed, and as a one when the jumper is removed. If the MVME162BUG firmware is installed, four jumpers are user-definable (pins 1-2, 3-4, 5-6, 7-8). If the MVME162BUG firmware is not installed, seven jumpers are user-definable
