Troubleshooting

munication is established. If a connection is not made within twenty seconds, the unit will exit programming mode and enter normal oper- ating mode. In this event, simply reboot power to the unit and try again.

After entering the program, a screen is displayed showing the current settings. The user may change the settings and then must click SAVE CHANGES AND EXIT. Upon exiting the program and cycling power to the unit, the settings will become effective. This screen offers the user five options.

PN Sequence. The channel-hopping sequence must be the same on the transmitter and receiver in order for data to be transferred properly. RSSI. The Received Signal Strength Indicator is used for receiver to monitor the radio spectrum on all hopping channels. It is presented as a bar graph of power (dBm) against frequency (MHz). Useful in trouble- shooting to determine if any other signals are present in the 900MHz band. Meaningless if connected to the PTZ-900TX.

Data Rate. The rate for PTZ data can be set between 1200 and 19200 bps. Parity can be set to odd, even, or none. The settings must be the same on the transmitter and receiver.

Mode. RS-232 (unbalanced) or RS-485/RS-422 (differential). Select the mode that matches your PTZ control equipment.

Address. Multiple systems deployed in the same area should have dif- ferent addresses. Similar to PN Sequence, the address setting must be the same on the transmitter and receiver in order for data to be transferred properly. You must click on SET ADDRESS to make changes effective

Interference or intermittent operation.

9Heavy equipment such as industrial, roof-mounted air conditioners or fan motors in close proximity to the transmitter, receiver, or cables may cause interference, especially when operating in RS232 mode. Move the unit/cable away from the source of the interference.

9Antenna polarization may be wrong. The normal polarization for the AD900-9 antenna is horizontal, since that has been determined to

give the best results in general.

9Raise transmitter and receiver antennas above ground and away from obstacles and traffic, including foot traffic.

9Verify that all connectors are tight, especially the power connectors.

9Shorten the receiver antenna feed cable. It is best to use only those cables supplied with the equipment.

9If the system becomes unusable for a period of time on the order of minutes or hours and then becomes usable again, changing the PN sequence may cure the problem. The different PN sequences have dif- ferent waiting channels that are used to synchronize the hopping se- quences. Depending on your environment, there may be a 900MHz transmitter interfering on one of the waiting channels. By changing the PN sequence of the transmitter and receiver, the waiting chan- nel will change. Some of the types of equipment that may interfere are 900MHz cordless phones and wireless LANs if they are very close to the PTZ-900RXreceiver antenna. The waiting channels are 924.2MHZ (default) PN0, 905.8MHz PN3, 911.8MHz PN2, and 918.2MHz PN1.

9High-power equipment operating near the 902–928MHz band, such as paging system base stations or cellular phone base stations, may also interfere if they are within several hundred feet of the receiver. Changing the PN sequence and reorienting the receiver antenna will most likely cure this type of interference.

9The cable from transmitter to PTZ controller may be too long, cor- rupting digital data. Use category 5 twisted-pair shielded cable, if possible, and a maximum length of four thousand feet for RS422 or one hundred feet for RS232.

9The cable from receiver to PTZ receiver/driver may be too long, cor- rupting digital data. Use category 5 twisted-pair shielded cable, if possible, and a maximum length of four thousand feet for RS422 or one hundred feet for RS232.

9Interference on video signal when sending PTZ data. Check the system’s grounding and use ground-fault isolation transformers if the problem persists.
