Internal EVS information
3.5.2.2 BOARD CONFIGURATION:
HPOL, VPOL and ENVS are used to configure the composite sync
generator used in LSM TV mode (no effect if LSM is only used with a VGA
monitor).
The HPOL jumper can be used to invert or not the VGA HS signal
(Horizontal Sync) to generate the composite output signal (TV mode)
The VPOL jumper can be used to invert or not the VGA VS signal
(Vertical Sync) to generate the composite output signal (TV mode)
The ENVS jumper can be used to enable or not the presence of the VGA
VS signal (Vertical Sync) in the composite output signal (TV mode)
If the LSM TV mode is used, these jumpers must be set-up according to
EVS recommendations, which depend on LSM software version and CPU
board model/revision:
With MPTC board A2/A3 or A2/A4, set up the jumpers as follows:
• HPOL=On; VPOL=Off; ENVS=On
REMOTE RESET jumpers are available to designate the
remote(s) from which the RESET command can be sent.
This command resets the whole system: PC and video
hardware.
In standard configuration only Remote one (on RS422 port 1) is allowed
to reset the system.
Important
This jumper should be removed if the device connected to the
RS422 port is NOT an EVS controller. Maximum voltage on pin 5
of an RS422 port of the XT server should not exceed 5 Volt when
the corresponding jumper is engaged. Applying a higher voltage
on pin 5 when the corresponding jumper is engaged will result in
permanent electronic damage to the board.
