OPTICAL SYSTEMS DESIGN 2 INSTALLATION AND OPERATION INTRODUCTION This section outlines the methods required to install and operate the OSD8816BT and OSD8816BR successfully. It should be studied carefully if damage to the equipment or poor results are to be avoided.
OPTICAL SYSTEMS DESIGN 2.2.2 DRAWINGS AND DIMENSIONS The OSD8816BTC and OSD8816BRC are designed to be mounted on an even surface and to be secured by means of M4 or smaller screws. The OSD8816BT and OSD8816BR card versions are designed to be inserted into a chassis and secured by means of captivated screws.
OPTICAL SYSTEMS DESIGN 2.2.3 POWER SUPPLY CONNECTIONS The OSD8816B card version is powered from the OSD370N or OSD350N chassis. DC power in the OSD881B6 card version is connected via a DB9 connector. The card version of the OSD8816BT and OSD8816BR should be fixed into the chassis using the captivated screws. Either card can be plugged in or out of the chassis with power on or off.
OPTICAL SYSTEMS DESIGN 2.2.4 OTHER CONNECTIONS The video-input signal (eg. from camera) is connected to the video input BNC connector on the OSD8816BT. The video output signal (eg. to monitor) is connected from the video output BNC connector on the OSD8816BR.
OPTICAL SYSTEMS DESIGN OSD8816B OPERATION 2.3.1 OSD8816BT AND OSD8816BR OPERATION When using the OSD8816B for the first time, check that the unit is in good condition with no visible damage. If a card version is used, insert it in an appropriate slot on the OSD370 or OSD350 chassis and check that the indicators illuminate accordingly on power up (see Table 5).
