(pins 6, 8, and 20 of j4 are connected together internally.) note: unidentified pins are not connected. warning: wrong connections or reversing j3 may cause permanent damage to the display and host interface. pin description interfacing parallel interface the parallel interface offers two forms of hand-shaking called ready and data taken. each 8 bit word appearing on the data bus is latched with the falling edge of the data strobe pulse. this same negative transition notifies the on-board proces- sor that data has been entered. the ready signal then goes low and the data taken signal goes low momentarily. the ready signal remains low until the command is completed or the data has been entered. the data taken pulse is normally 800 nanoseconds long and indicates when the on-board processor has read the input latch. data may be entered into the input latch after the rising edge of data taken. serial rs-232c interface (see j4 pin descriptions.) the controller is considered to be a dte type device and will operate with a host that is either a dte or dce type device. the serial input and output lines meet rs-232c specifications. serial data is entered asyn- chronously with selectable baud rates. the byte format is 1 start bit, 8 data bits and 1 stop bit. description part number display, drive electronics, controller board (includes dc/dc converter) ........................................................ ...............
