brightsign 410 new user - sync problem

Couple of things:
I'm having problems with my sync.
Two 410s, two 12min videos exactly the same frame length, encoded as .m2t/ac3 files with the audio for both channels playing out to a speaker from the master unit only. They are to be synced and looped for exhibition. It is imperative that they run in sync but it appears to be off by about 1sec.
I'm using a sync script and loop script that was written by the company that sold me the units and have amended the video file-names for both slave and master appropriately. I can post this if necessary. I'm on Mac OS10.4.11 so cant use the authoring software.
The GPIO cable arrived with the adaptors unconnected and some six-core cable. I have them wired as per the diagram below, is this correct?
0V empty 0V
7 empty 7
6 empty 6
5------5
4------4
3------3
2------2
1------1
0------0
0V empty 0V

Any ideas?

  Here are the two scripts:
  
  
  
  THE MASTER SCRIPT
  
  
  
  delay=1000
  
  
  
  'You can comment out the delay keyword above to remove artificial 1 second delay on master
  
  'Setting outputs to low, by setting whole state on gpio zero
  
  'v 11-03-09
  
  videoFile1 = "NAGRA_L.ts"
  
  
  
  v = CreateObject("roVideoPlayer")
  
  gpio = CreateObject("roGpioControlPort")
  
  p = CreateObject("roMessagePort")
  
  v.SetPort(p)
  
  gpio.SetPort(p)
  
  
  
  mode=CreateObject("roVideoMode")
  
  mode.SetMode("1920x1080x25p")
  
  
  
  
  
  gpio.EnableOutput(0) 'not used for any signaling; turns all gpios off except 0
  
  
  
  'preload signal
  
  gpio.EnableOutput(1)
  
  gpio.EnableOutput(2)
  
  gpio.EnableOutput(3)
  
  
  
  'playsignal
  
  gpio.EnableOutput(4)
  
  gpio.EnableOutput(5)
  
  gpio.EnableOutput(6)
  
  
  
  gpio.SetWholeState(2^0)
  
  sleep(10000)
  
  
  
  attract_loop:
  
  ' Toggle GPIO0 to indicate "preload video1"
  
  gpio.SetWholeState(2^1+2^2+2^3)
  
  
  
  v.PreloadFile(videoFile1)
  
  sleep(20)
  
  gpio.SetWholeState(2^0)
  
  
  
  ' Now wait a short while to ensure the slave has Preloaded too
  
  sleep(100)
  
  gpio.SetWholeState(2^4+2^5+2^6)
  
  sleep(delay)
  
  v.Play()
  
  sleep(20)
  
  gpio.SetWholeState(2^0)
  
  
  
  listen:
  
  
  
     msg = wait(0,p)  
  
     if type(msg) = "roVideoEvent" and msg.GetInt() = 8 then
  
  sleep(1000)
  
  goto attract_loop
  
     endif
  
  
  
  goto listen
  
  
  
  
  
  AND THE SLAVE SCRIPT
  
  
  
  videoFile1 = "NAGRA_R.ts"
  
  
  
  v = CreateObject("roVideoPlayer")
  
  gpio = CreateObject("roGpioControlPort")
  
  p = CreateObject("roMessagePort")
  
  v.SetPort(p)
  
  
  
  mode=CreateObject("roVideoMode")
  
  mode.SetMode("1920x1080x25p")
  
  
  
  sleep(200)
  
  gpio.EnableInput(1)
  
  gpio.EnableInput(2)
  
  gpio.SetPort(p)
  
  
  
  
  
  listen:
  
  msg = wait(0,p)
  
  if type(msg) = "roGpioButton" then
  
     if msg.GetInt() = 1 then
  
  v.PreloadFile(videoFile1)
  
  
  
     elseif msg.GetInt()=2 then
  
  v.Play()
  
     endif
  
  endif
  
  
  
  goto listen

  I sent you an email on this issue...
  
  
  
  I wanted to verify the firmware on your units. They should be 3.1.73 or later. There's a variable "delay" that's set to 1000. This is one second. Try setting that to zero and see if it fixes the problem. We can also try adding a delay on the slave to compensate.
  
  
  
  If the slave is getting signaled to play, then you have the cables wired correctly.
