210-065 Question #9: Real Exam Question with Answer & Explanation
The correct answer is D: a VISCA cable (DB9-to-RJ45). PTZ camera control from a C-Series codec requires a VISCA cable with a DB9 connector on one end and an RJ45 connector on the other, not a standard Ethernet cable.
Question
When connecting to a pan-tilt-zoom camera to a C-Series codec, what type of cable must be used for camera control?
Options
- Aan Ethernet crossover cable (RJ45-to-RJ45)
- Ban Ethernet cable (RJ45-to-RJ45)
- Ca serial cable (DB25-to-DB9)
- Da VISCA cable (DB9-to-RJ45)
Explanation
PTZ camera control from a C-Series codec requires a VISCA cable with a DB9 connector on one end and an RJ45 connector on the other, not a standard Ethernet cable.
Common mistakes.
- A. An Ethernet crossover cable carries IP traffic between two hosts and cannot transmit the serial VISCA control signals required for PTZ camera movement.
- B. A standard Ethernet straight-through cable is used for IP network connectivity and does not support the serial VISCA protocol needed for camera control.
- C. A DB25-to-DB9 serial cable is a legacy RS-232 adapter and does not match the RJ45 interface on the PTZ camera side.
