Basic Specifications

Model: JANCD-GRT01 (abbreviated as GRT01)

Type: CRT display / I/O control board

Compatible systems: YASNAC 2000G, 3000G

Power supply: DC5V (direct supply from the back panel)

Form: Full-length industrial board card, gold finger slots

Temperature: Working range 0℃~+55℃; Storage range -25℃~+85℃

Humidity: 30%~95% RH (no condensation)

Interfaces and indicators

CN1/CN2: CRT video output (including line / field synchronization, suitable for monochrome CRT)

CN3: General I/O interface (input / output signal conversion)

System bus: High-speed communication with GMM11/GMM12

Panel interface: Connects to MDI operation panel / keyboard

Indicators: PWR (power), RUN (operation), ALM (alarm) Core function

Display driver: Controls monochrome CRT, outputs basic interfaces such as coordinates, programs, tool compensation, and alarms

Graphics processing: Basic trajectory display, two-dimensional simulation of tool paths, suitable for common processing scenarios

Interface management: MDI editing, parameter setting, program browsing, alarm information display

Data interaction: Real-time exchange of display data and operation instructions with the main CPU of GMM

I/O control: Integrated general input/output points, simplifying signal conversion for machine tools (such as limit switches, zero return)

Different from GMR22/GMR24/GRS01

GMR22: Pure graphics display board, without integrated I/O

GMR24: Enhanced graphics display board, without integrated I/O

GRS01: High-end graphics + serial port board, without integrated I/O

GRT01: Basic display + integrated I/O, high性价比， suitable for economy-type machine tools

Installation and maintenance

Installation： Backplane slot on the same slot as GMM11/GMM12， vertically locked

Wiring： Backplane DC5V power supply， away from power lines； Shield the CN3 interface

Maintenance： Regular dust blowing， cleaning gold fingers； Check interfaces for no looseness

Faults： No display (power supply / poor contact)； Screen flickering (chip / communication abnormal)； I/O failure (interface damage / signal abnormal)
