PGM OUT 1, 2, 3: These three BNC connectors are used for the program video output. The output
video standard is the same as the input video standard. The PGM OUT 1 output is
protected by a bypass relay, which will activate in the event that power to the
module is lost or the module is removed.
identical to PGM OUT 1 except that these outputs are not bypass relay protected.
GLCK IN: This BNC connector is used as the Genlock input. The Genlock signal may be
NTSC or PAL colour black. The reference input type is auto-detected.
The input program video and fill video must be in the same video standard as the
genlock colour black and clock locked (constant phase) with respect to the genlock
signal.

GENERAL PURPOSE INPUTS

The 6-pin terminal strip has four general purpose inputs (GPI's). The GPI's are active low with internal
pull-ups to +5 or +12 volts DC, set by jumper J16 (see section 8.3 and Figure 8-1). If an input is left
floating (not connected) it will not be activated. Lowering the GPI input to a voltage below 0.5 volts will
activate the input. GPI's can be activated by simply connecting the GPI input pins to ground using a
button, switch, relay, or an open collector transistor.
