C
Always use a power supply specified by Extron for the YCS SW2 A. Use of
an unauthorized power supply voids all regulatory compliance certification
and may cause damage to the supply and the YCS.
Step 7 — Enable auto-input switching (optional)
To set up the YCS to automatically select the active, connected input:
a. Use two jumper wires to connect pins 1 and 2 and pins 2 and
3 of the provided 3-pin captive screw connector. Tighten the
screws to hold the jumper wires securely in place.
b. Insert the captive screw plug into the Contact/Auto-SW
connector as shown at right.
Step 8 — Enable black and white mode (optional)
To enable the YCS to detect NTSC signals that are black and white only, place the switcher in
black and white mode as follows:
a. Remove the four case screws on the sides of the
unit and lift off the top cover.
b. Locate the jumper at JMP1 and SW1 on the YCS
internal board (behind the front panel buttons).
Place the jumper onto both the SW1 and JMP1
pins.
C
When placing the jumper on the two
pins, ensure that the fine wire connecting
the two sleeves of the jumper is at the top
(outside). Do not attempt to force the
pins through the wire.
c. Replace the case cover.
Step 9 — Power on
Apply power to the YCS, the input sources, and the output devices.
Selecting Inputs by Contact Closure
The Contact/Auto-SW connector on the YCS rear panel enables optional remote input
switching via a latching contact closure device (as
an alternative to auto-input switching, described in
step 7, above).
To switch inputs using contact closure:
a. Connect a latching contact closure device to
pins 1, 2, and _ of the Contact/Auto-SW
connector on the rear panel.
b. To select input 1, momentarily short pin 1 to
the _ pin. To select input 2, momentarily short
pin 2 to the _ pin.
