#INSTACODE 1284X DRIVER#
Depending upon the type of driver used, a series resistor, Rs may be required to obtain the correct impedance.Welcome to /r/locksmith, the virtual break room for Locksmiths of Reddit. It is intended that this impedance match the cable impedance so as to minimize the noise caused by mismatched impedances. Ro represents the output impedance at the connector. The receiver low-level input source current shall not exceed 20uA at +0.8V.Ĭircuit and stray capacitance shall not exceed 50pF.įigure 1 shows the recommend termination for a driver/receiver pair.
The receiver high-level sink current shall not exceed 20uA at +2.0V. The receiver shall provide at least 0.2V input hysteresis, but not more than 1.2V. The receiver low-level input threshold shall be at least 0.8V. The receiver high-level input threshold shall not exceed 2.0V The receiver shall withstand peak input voltage transients between -2.0V and +7.0V without damage or improper operation. Like the driver requirements, the receiver requirements are defined at the connector interface. The driver slew rate shall be 0.05-0.40 V/nS The driver output impedance (Ro), measured at the connector, shall be 50 +/- 5 ohms at 1/2 the actual driver Voh minus Vol voltage. The DC steady state, low-level output voltage shall not exceed +0.4V at a sink current of 14mA. The DC steady state, high-level output voltage shall be at least +2.4V at a source current of 14mA. The open circuit low-level output voltage shall be no less than -0.5V. The open circuit high-level output voltage shall not exceed +5.5V.

The requirements for the Level II drivers and receivers are defined at the connector interface.

Please refer to the standard for the full requirements for either a Level I or Level II interface.
This discussion will deal primarily with Level II interfaces. The Level II interface is for devices that will operate in the advanced modes, with long cables, and at the higher data rates. The Level I interface is defined for products that are not going to operate at the high speed advanced modes, but need to take advantage of the reverse channel capabilities of the standard. The 1284 standard defines two levels of interface compatibility, Level I and Level II. Host adapters and peripherals were built with any number of pull. capacitance requirements in order to guarantee any compatibility between devices. This type of design variation makes it impossible to create a new interface protocol without explicitly defining the required electrical parameters with which to guarantee operation. The original parallel port did not have a defined electrical specification that identified the driver, receiver, termination and up values on the control lines, open collector or totem pole drivers for the data and control lines, and most offensive of all, up to 10,000pF capacitors on the data and strobe lines. 1284 is like RS232 it defines the connector and protocol not a print driver like postcript or HPGL or PCL.
