    Data Transfer Speeds…… 4 Introduction The Digital488/80A is a digital input and output interface to the IEEE 488 bus that enables an IEEE 488 controller to program 80 bits of TTL level signals as either inputs or outputs. It includes six handshake/control lines for each 40-bit channel and two addressing modes.

  • Page 9: Hvcx1 High Voltage/Current Interface Option

    -- a requirement for process control applications. Internal Buffer A built-in data buffer in the Digital488/80A can store up to 8,000 bytes, which is large enough to capture two thousand patterns from one 40-bit I/O channel. When interfacing to slow devices, the data buffer relieves the controller of the need to constantly read data from the Digital488/80A.

  • Page 10: Specifications

    Each high-current output is capable of sinking up to 200 mA at 50 VDC maximum. Total current sinking capability is 8 A maximum. Update Rate: In binary mode, the Digital488/80A can update one 40-bit I/O channel at over 2 Kbytes per second.

  • Page 11: Data Transfer Speeds

    The Digital488/80A has been measured to perform at the approximate speeds listed below. The testing was done in such a way that the limiting factor was the Digital488/80A and not the IEEE 488 bus controller driving it. All explanations discuss only one channel although the specifications given are valid for either channel.

  • Page 15: Dual Primary Addressing Mode

    Dual Primary Addressing Mode The Digital488/80A can be thought of as two identical IEEE 488-to-digital I/O interfaces. Each interface occupies one bus address and has one I/O channel. For this reason the Digital488/80A occupies two bus addresses in an IEEE 488 system.

The Digital488/80A has two DB-50 connectors -- Channel 0 and Channel 1 -- each of which provides 40 data lines programmable in groups of 8 bits as either input or output ports. The following figure illustrates one of the digital I/O DB-50 connectors as viewed from the rear panel of the Digital488/80A.

    For example, a typical application may require a lamp and a relay to be driven by the Digital488/80A. The relay is connected to data line 27 (Port 4) and the lamp is connected to data line 37 (Port 5). These two ports must be configured as high-level outputs.

    Introduction Internal Components The heart of the Digital488/80A is a 6809 microprocessor [U1] supported by 8K bytes of firmware EPROM [U2] and 32K bytes of battery-backed-up RAM [U3]. Interface to the IEEE 488 bus is accomplished by a 9914 interface chip [U13]. A 65B22 [U14] generates real-time interrupts for the firmware operating system and also drives the front panel LED indicators.

  • Page 27: Power Line & Fuse Configuration

    The power configuration of the Digital488/80A unit consists of selecting the line voltage and replacing the fuses. Each Digital488/80A unit has a factory default to operate at 105-125 volts AC. However, each unit may be operated at either 105-125 or 210-250 VAC.

    Rack-Mount & Bench-Top Assembly The Digital488/80A includes accessories for rack-mount or bench-top assembly. Rack Mount If rack-mount assembly is required, remove the two plastic screws from the pre-drilled holes on each side of the unit. Since the unit can be mounted with the front or rear panel facing the front of the rack fixture, remove only those screws from the set of holes that will be toward the front of the rack.

If EDR changes again before the previous EDR buffered data has been output, the Digital488/80A generates an EDR Overrun error and ignores the EDR read request. After output in the F0 through formats, the Digital488/80A must be readdressed to Talk to perform subsequent buffered output of EDR captured data.
