ダプタ。 A transmitter connector that is connected to a device that has a GP-IB standard interface (GP-IB side device), and a device that is connected to this transmitter connector via a cable and has a Centronics standard interface (printer). and a receiving side connector connected to the GP.
- An inverter that inverts and inputs signals from the GP-IB side equipment sent to the data lines DIO1 to DIO8 of the IB to the printer, and three-wire handshake lines DAV, NRFD, and NDA of the GP-IB.
C Each signal and Centronics interface S
A control circuit that uses the TROBE and BUSY signals as input/output signals is provided inside the receiving connector, and when in the data mode, the 3-wire handshake line DAV, NRFD, and NDAC signal lines and the STROBE and BUSY signals are connected to each other. The control circuit is operated by signals sent and received between the signal lines, and through the control circuit, the interface is converted from GP-IB to Centronics, and the data line D
Data transmission is performed through IO1~8, and when in command mode, GP-IB
An interface conversion adapter configured to control the control circuit with an ATN signal on the side and to inhibit data transmission through the data lines DIO1 to DIO8.
