Display Configuration: Display configuration refers to a display’s model number, address, etc.
This information will be automatically displayed when the display is powered up. Display configuration
is as follows:
1. Output Test (DDD’s)
2. Display Model Number (i.e. S-100-12-24-0.7)
3. Firmware Version
4. COM1 Configuration (typically V1500)
5. COM2 Configuration (either DataView

or RTD)
6. Power Line Frequency (i.e. 60 Hz)
7. Display Address – displayed in binary code (i.e. 001)
8. Sign Name
9. Modem (if present)
Flipped Cable: The flipped cable is a six (6) conductor phone cable. Pin 1 of connector A connects
to pin 6 of connector B.
LAN: Local Area Network
Loop Back Test: The loop back test is a troubleshooting test that connects the output to the input.
Contact Daktronics customer service for this test.
Module: A module is one unit of the display. A module for a 0.7
@ display consists of 4 lines by 12
characters of LEDs. The 1.2 @ and 2.1@ displays= modules consist of 4 lines by 6 characters.
Network: A network consists of multiple signs connected to each other. Up to 240 Venus 1500
controlled displays can exist on one network.
RS232: RS232 is a standard PC communication type with a maximum cable length of 25 feet (7.62
meters).
RS422: RS422 is a standard differential communication type with a maximum cable length of 4000
feet (1.2 kilometers).
RX LED: A RX LED is a LED on the signal converter that indicates if the display is sending data
back to the signal converter.
Serial Server: A serial server is a device used to obtain information off of a LAN.
Sign Address: The sign address is an identification number assigned to each sign of a network. The
control software uses the address to locate and communicate with each display. Displays that are on
the same network cannot have the same address.
Signal Cable Tester: The signal cable tester is used to test the cable connections and data
communication.
