Board Configuration
HPOL, VPOL and ENVS are used to configure the composite sync generator used in LSM
TV mode (no effect if the server 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 software version and CPU board model/revision:
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.
