For pinout details, refer to the section dedicated to the pinout in Appendix A, "Standard connector pinouts", page 505.
Genlock Input BNC (with passive Loop-through)
The Genlock input supports analog NTSC and PAL Blackburst, as well as HD tri-level sync signals, per SMPTE 274M and SMPTE
296M. The passive loop-through connector passes the Genlock signal to another device downstream of the Event Master series
processor. The Loop-through output will continue to function even when the device is turned off. When the device is genlocked
and the lock source is lost, the output of the unit will automatically switch to "free-run" state without any discernible "glitching" on the
output display device. As the loop-thru is passive a 75Ohm termination is necessary for stable operation.
For Genlock connections details, refer to the Specifications Appendix.
Expansion Link cards
When event requirements exceed the capacity of a single unit in terms of input, output, or number of layers, multiple Event Master
processors can be linked together through the Expansion Link cards. The cards are connected with Barco-supplied, high-bandwidth,
bi-directional Expansion Link cables. These cables are also commercially available.
Depending on the Event Master processor model, two, one, or no slots are reserved at left side of the rear panel for Expansion Link
cards.
E2
1, 2
1 E2 Jr. and S3–4K Jr. do not have Link cards, but these models can be upgraded with Link cards, which
would go into the same slots as the Link cards on the E2 and the S3–4K.
The EX has two (2) Expansion Links integrated in the chassis.

For more details on capabilities of expansion, refer to the section "Expansion Link card", page 60.
VPU cards
VPU (Video Processing Unit) cards are at the heart of the Event Master Series of products. All scaling, layer effects and image
compositing happens within these cards. Each card supports the scaling requirements for the product line with the award-winning
Athena scaling technology at resolutions up to 4K. Due to their reprogrammability any future video processing capabilities will be
implemented in these cards. Current capabilities include:
• Support for 2K, Dual-Link, and 4K Scaling
• Layer compositing over unscaled Backgrounds
• Layer effects, including Borders and Shadows
• Keying effects
• Key frame effects
On an E2 and E2 Jr. units, the VPU cards are not accessible through the rear panel. On S3–4K and S3–4K Jr. units, slots 2 and 3
are reserved for the VPU cards. The EX expansion box has no VPU cards.
For more details on VPU card, refer to the section "VPU card", page 61.
Input cards
Each input card supports resolutions of up to 4K. The ability of the Event Master processors to support up to 28 inputs (E2) eliminates,
in most cases, the need to have upstream routers or scalers.
Each card slot could accommodate either:
• 4x up-to HD/2K inputs
• 2x 2560x1600 inputs
• 1x 4K input
On an E2 (or an E2 Jr.) processor, slots 3 through 10 are reserved for input cards. On an S3–4K (or an S3–4K Jr.) processor, slots
4 through 6 are reserved for input cards. Both slots of an EX expansion box may hold input cards, but if the EX has both an input
and an output card, the input card should go in slot 1.
The following sections describe each type of card in detail:
• "SDI Input Card", page 49
• "Dual Link DVI Input Card", page 51
• "HDMI/DisplayPort Input Card", page 53
Outputs cards
Event Master series processors support HDMI and SDI output cards. Each output card supports resolutions of up to 4K.
On an E2 (or an E2 Jr.) processor, slots 11 through 13 are reserved for output cards. On an S3–4K (or an S3–4K Jr.) processor,
slots 7 and 8 are reserved for output cards. Both slots of an EX expansion box may hold output cards, but if the EX has both an
input and an output card, the output card should go in slot 2.
