It is provided with a power supply for the boards installed, and a Local CPU board to control boards in the cage. ■ Appearance • Front View • RearView G) Operate Indicator (OPERATE) Is on when the power of the WJ-SX850 Matrix Switcher Card Cage is turned on. Note: The power switch of this cage is located underneath the front panel. Remove the front panel by removing two screws on the panel. CD VS/VD Input Connector (VS/VD IN) Accepts either the VD (Vertical Drive) pulse or the VS {Video Sync) signal for synchronizing the system. Notes: • This input is looped through to the VS/VD Output Connector. • When the VD (or VS) signal is supplied to the VS/VD Input Connector, turn the VS/VD selection switch (SW7) on the circuit board to the VD (or VS) position. The factory default setting of the VS/VD selection switch (SW7) is VD. Ask qualified service personnel about setting up this switch. • The external sync signal should meet EIA RS-170 specifications and should not contain any jitters, such as a VCR playback signal. -2- (D VS/VD Output Connector (VS/VD OUT) Outputs either the VD (Vertical Drive) pulse or the VS (Video Sync) signal for synchronizing other system components. Note: The input at the VS/VD Input Connector is looped through to this output. These inputs and outputs are connected internally. 0 VD Output Connector (VD OUT) Outputs VD (Vertical Drive) pulses for synchronizing other system components. Notes: • The internal VD pulse or the looped-through external VD pulse is provided at this connector. • When the VS signal is supplied to the VS/VD Input Connector, the VD output signal from the VD Output Connector will be delayed by approximately 15 ps with respect to the V-sync of the VS input signal. 3H v VS input signal VD output signal t--1 r approx.

(D AC Inlet Socket (AC IN) Plug the power cord (supplied as a standard accessory) into this socket and connect the cord to an AC outlet. ■ Board Setting The following settings should be made by qualified service personnel or system installers. 1. Remove the front panel by removing two screws on 2. Extract the Local CPU board by raising up the card the panel. puller. — Caution - Hold this board only by its edges.
