The ADV11-C is an LSI-11 analog input printed circuit board, a8000. It accepts up to 16 single-ended inputs, or up to 8 differential inputs, either unipolar or bipolar. A unipolar input can range from 0V to 10V. A bipolar input can range from -10V to +10V. The ADV11-C also has a programmable gain on those inputs of 1, 2, 4 or 8 times the input voltage.

The DRV11 is a general-purpose interface unit used for connecting parallel-line TTL or DTL devices to the LSI-11 bus over up to 25 feed of cable. It permits program-controlled data transfers at rates up to 44K words per second (with optimized programming) and provides LSI-11 bus interface and control logic for interrupt processing and vector generation. Data is handled by 16 diode-clamped input lines and 16 latched output lines. Device address is user-assigned and Control/Status Registers (CSR) and Data Registers are compatible with PDP-11 software routines.

Analog-to-digital (A/D) conversions are started by a program command, an external trigger, or a real-time clock input. When the program command sets the A/D START bit in the control/status register, the ADV11-C starts the A/D conversion on the input channel selected.

The ADV11-C changes the analog input into digital data. The digital data goes to the A/D data buffer register and waits for a programmed data transfer to the LSI-11 processor or memory, or the ADV11-C puts an interrupt request on the LSI-11 bus and waits for the interrupt request to be acknowledged.

DRV11 Parallel Line Unit

The DRV11 is a general-purpose interface unit used for connecting parallel-line TTL or DTL devices to the LSI-11 bus over up to 25 feed of cable. It permits program-controlled data transfers at rates up to 44K words per second (with optimized programming) and provides LSI-11 bus interface and control logic for interrupt processing and vector generation. Data is handled by 16 diode-clamped input lines and 16 latched output lines. Device address is user-assigned and Control/Status Registers (CSR) and Data Registers are compatible with PDP-11 software routines.
