LCD
Setup - Part 1 |
| |
When
I first got the LCD, I was a little afraid that I'd screw something
up and have to buy a new one. So at every point I checked and double
checked to make sure that I don't fry the LCD (which I end up doing
later on anyway.) So first I went to the ECSC website and downloaded the pinouts
for the LCD. Here they are: |

1
- Chassis Ground
7 - Lo Video (-) } Differential, composite video
8 - Hi Video (+) NTSC
9 - Video Shield } Negative sync
10 - DC Supply return
11 - +12V DC Supply
12 - Data Screen } differential, RS485
13 - Hi Data(+) } 9600 baud, 8 data bits
14 - Lo Data(-) } 1 Stop, 1 parity bit |

I
only needed pins 7,8,10, and 11 to make the LCD work. Pins 7 &
8 get connected to a RCA cable that hooks to my video card. The
LCD uses NTSC signals instead of regular VGA signals, so you have
to find a video card with TV out. Pins 10 & 11 supply the power
needed to run this beast. The LCD runs on 12V DC which is perfect
for the car, but to get it running on the household AC power so
that I could test it, I had to run to radio shack and get a 120VAC to 12VDC inverter (Cat. #22-502)
for about $25. It's the smallest one they have and it works perfectly.

ECSC
didn't send me any sort of connector cable for the LCD. I don't
know if it's not included or if they just forgot, so I had to improvise
MacGyver style. I cut off the power cables for a floppy drive in
an old PC. They can only connect to four pins each so I cut two
of them and pulled out two wires on each connector (I didn't want
extra wires hanging out). (View images below) So far I haven't had
any problems with the connection. |

Get a female RCA cable instead of a male. |
