● Provides GPIB to Centronics or to 1284 Printer Interface. Drives virtually all parallel printers. ● Large 252 Kbyte buffer and high GPIB data transfer rate. Speeds up GPIB data transfers and off loads PC. ● Stores GPIB address and interface settings in E2ROM. Configure unit without having to remove the cover. ● IEEE-488.2, IEEE-1284 compatibility and SCPI commands. Meets the latest programming specifications. ● Includes 4892B to Printer Cable and Support CD. Nothing more to buy. ● Includes menu-driven, configuration programs and ICS's interactive GPIBkybd program. Easy configuration changes with most GPIB controllers. ● 1U high, thin box design with optional rack mounting hardware kit. Small unit saves space.
The 4892B is a GPIB-to-Printer Interface that transparently transfers data from a GPIB bus to any printer or plotter with the industry standard 'Centronics' or IEEE-1284 Parallel Interface. The ICS GPIB-to-Printer Minibox 4892B includes a 256K RAM that buffers up to 252,000 characters and a high > 600 kbyes/second transfer rate that minimizes data transfer time and free's the GPIB Controller for other tasks while the ICS GPIB-to-Printer Minibox 4892B finishes the data transfer. Applications include replacing obsolete GPIB printers and plotters with newer parallel printers, driving a printer from a GPIB instrument or buffering print data from a GPIB controller.
Bus drivers incorporate powerup/down protection to prevent sending invalid data to the bus.
Address Capability
Primary addresses 0-30 and listen-only
SRQ Generation
SRQs are generated if the unit is not addressed to talk, if SRQs are enabled and one of the following occurs.
SRQ Generation in ICS 488.2 Mode
GPIB Buffer empty
GPIB Buffer full
Enabled ESR bit occurred
SRQ Generation in PRL Emulation Mode
GPIB buffer empty
Escape Sequence
In G-Mode the 4892B powers up in the transparent Data sub-mode. A Device Trigger is used to switch from Data to Command submode. SCPI SYST:OPER DATA command is used to switch back to the Data sub-mode. 4892A units used a Listen-Unlisten escape sequence to switch from Data to Command sub-mode.
The 4892B's parallel interface conforms to the Centronics and IEEE-1284 Standard specifications
for Compatibility Mode and Level 1 Drivers. Data is transferred as 8-bit bytes.
