STARTING UP THE S7999D OI DISPLAY
Power-up Validation
The Home page will appear when the device is properly powered. Select the Setup button to adjust the contrast and sound as desired.
If the screen is dim, check the pin 7 and 8 wiring connections.
A “camera” icon on the left top corner is for screen snapshot use. Up to 16 snapshots can be stored in the display and can be copied
to a USB memory stick.
Note: An Advanced Startup screen displays for five seconds after power-up before the Home page displays. This screen allows the
user to upgrade the software in the System Display and should normally be bypassed.
Three LEDs exist for I/O traffic: one for the Ethernet network port and two for Modbus™ ports. Modbus Com Port 2 is not active on
this device.
1. Make sure the Power and COM1 LEDs are blinking.
2. If the LEDs are not blinking:
• Make sure the proper connections have been made between the Modbus COM1 Port and the first controller device in the
Modbus network.
• Ensure proper wiring of the OI Display 9-pin Header Connections.
3. If connected to a BAS application, COM2 LED will blink indicating BAS traffic.
