at all. If you encounter this condition, check if the BNC cable is defective or
improperly connected. Often, the user will neglect to fully twist the BNC connector
after installation to lock it into place.

Q: Which pan/tilt/zoom mechanisms can be installed with the VersaCam?
A: While the IC-360 contains its own pan/tilt/zoom mechanism, the other members of the
VersaCam IC Series family also have the ability to control external pan/tilt/zoom devices
on-line. Such PTZ devices are connected to the VersaCam through its DB-15 port or Terminal
Block interface in the rear panel (the connection method depends on the VersaCam model).
Consult the manual for your model of VersaCam to determine whether RS232 or RS-485
devices are appropriate, and which pins are to be used from the DB-15 connector for this
purpose.
Using the RS-485 connection, you can install various models of Pelco and the PTZ devices of
several other U.S. companies. The VersaCam can be programmed to send specific commands
to control pan, tilt, zoom and focus functions in response to commands. You can also install
pan/tilt/zoom devices that use an RS232 or RS-422 interface to the VersaCam's RS232
connections. Some VersaCam models are already programmed for support of Pelco's D and P
protocols. When using Pelco products, it is necessary to employ a signal level converter to
shift the RS232 output of the VersaCam to the RS-422 levels required by the Pelco device.
These converters are sold at any outlet carrying Pelco products, or at many computer interface
specialty companies such as Blackbox Co.
With RS232 connections, you can install the pan/tilt driver of Surveyor Co. and other vendors.
For detailed descriptions of the interface connections, please refer to Appendix 7.

Q: It is impossible to assign an IP address to the VersaCam with the ARP command.
What is the problem?
A: The ARP command may only be used on a local network. With a PC or a notebook
computer, you can assign an IP address to any VersaCam connected on a local network with
the ARP command or with the VersaCam setup program. If you cannot assign an IP address to
a VersaCam with the ARP command, you should check the following:
First, observe the green LED in the rear of VersaCam. Disconnect and then reconnect power to
the camera. When you supply power to the camera, the green LED comes on for about two
seconds then and then turns off. Afterwards it blinks once about every two seconds. If the
green LED begins to repeat blinking on for four seconds and off for one second, there is a
problem with the network connection. There are several possible reasons for this, including
using the wrong (crossover vs.. straight through) network cable, no real network connection
from the wall jack to the network, the use of a hub that supports ONLY 100BaseT connections
(the VersaCam requires 10BaseT), and other conditions. If the network connection is faulty,
you should check whether your network cable is of the correct type and works properly and
that the host or hub can handle 10BaseT connections.
If the green LED blinks normally, check the IP address of the PC or notebook computer being
used to ARP the camera. As explained before, the ARP command may only be used across a
local network. To be connected across a local network means that every device on the network
uses the same starting numbers of the local IP address (e.g. if your computer's address is
204.131.189.xxx, you should only be attempting to ARP assign a similar 204.131.189.xxx
