INSTALLATION/OPERATION MANUAL COAXITRON SYSTEM 2000 1.0 WARNINGS Prior to installation and use of this product, the following WARNINGS should be observed. 1. Installation and servicing should only be done by Qualified Service Personnel and conform to all Local codes. 2. Unless the unit is specifically marked as a NEMA Type 3-6P enclosure, it is designed for Indoor use only and it must not be installed where exposed to rain and moisture. 3. The product bears the following marks: 4.
NOTE: This manual applies to those Coaxitron systems using either PCB1500529 REV J or PCB1500529 REV K boards. PCB board drawings were done from the REV J board perspective; however, differences between the two boards that affect function or operation are clearly pointed out. Coaxitron System 2000 is an improved version of the original Coaxitron. Improvements include the following features: 1.
Remove PC board mounting screws and remove the PC board. If necessary, tag and remove any affected cables attached to the PC board. Remove or loosen the four patch panel mounting screws indicated below to gain access to patch panels T1, T2, and T3.

4.2 CONNECTOR ASSEMBLY Installation and/or testing will require you to assemble the connector parts provided. Fabricate the interconnecting cable according to the following steps (reference Figure 4). 1. Slide part A of the cable clamp (item 1) over the end of the cable (item 1, part C) with the threaded end of the cable clamp facing the connector (item 5). 2. If the cable has a diameter less than 1/2 inch (1.

Figure 7 shows the addition of a manual video switcher and one receiver/camera. In this example, the active coaxial cable is terminated in the transmitter and the inactive cables are terminated in the switcher. The selected camera signal is fed to the Coaxitron transmitter, which then feeds the monitor. When a camera selection is made, that video line is dedicated to the transmitter that allows the associated Coaxitron receiver to be controlled.
A more complex system is shown in Figure 8. Here, several control locations can serve a single camera system. Note: All transmitters, except the last one, must be looping (unterminated) rather than terminating. This monitor may also be used for sequential switching. As in the previous configuration, any one transmitter can assume control. If two or more control units are activated simultaneously, erroneous responses are prevented by error detection circuitry in the associated receiver.

5.0 OPERATION In general, all operating controls on the transmitter are self explanatory. With the exception of the ON/OFF power switch and the 8-position joystick, all controls are center-off, spring return paddle switches (momentary on-off-on). 5.1 FUNCTIONAL CIRCUIT DESCRIPTION The basic functional concept of the Coaxitron system is that 15 control pulses are fed in a reverse direction from the control transmitter to the receiver located near each camera station.
As an example, assume that the operator switches to manual iris control and proceeds to open the iris excessively. The result can be a complete loss of control. Within 20 to 40 seconds, camera power is automatically removed (assuming this feature exists) and auto iris is reinstated. Thus, distortion products are eliminated if the camera power function is incorporated in the system or reduced to a tolerable level if only the AUTO/ MANUAL iris function is incorporated. 5.
• Receiver Control Output for 12 VDC Camera Option The usual output for camera power is 24 VAC accessed at pins 9 and 14 of the 37-pin AMP connector (see Fig. 5) where CAM AC HIGH and AC LOW emerge as CAMERA INPUT POWER. The output pin assignments remain the same for 12 VDC camera power options, only now pin 9 (WH) is positive (+) and pin 14 (WH/ YEL) is negative (-). • Transmitter Video Input The transmitter usually provides for the 75 ohm termination of the cable from the receiver.
Up to 32 presets can be stored in each receiver. Up to 8 presets can be activated by alarm contacts connected to the receiver. There is also an open collector output from the receiver to activate an external device (such as the CSA764) when the alarm contacts are activated. Figure 11 shows the wiring for alarmed presets. The pan/tilt will “nod yes” if the receiver reads the feedback voltages (preposition lens) or “nod no” if it does not read any feedback voltages (manual lens).

5.6 AUXILIARY FUNCTIONS examples of typical circuits used for auxiliary functions. The Coaxitron receiver is capable of operating up to four (4) remotely activated auxiliary functions. Each auxiliary output may be individually converted at the receiver for momentary or latching operation. Refer to Figure 15 for the desired jumper location. When in the latching mode, activating the same AUX function will toggle the function from on to off.

5.7 AUTO/RANDOM OPERATION The A9000 Auto/Random Scan module is a plug-in P.C. board option (See Fig. 19 for board location) for all Coaxitron receivers. This module provides two modes for automatically controlling pan and tilts within preset limits — Auto Scan and Random Scan. The Random Scan and Auto Scan functions are controlled by the same momentary switch on the control panel labeled AUTO and MAN. The first activation of the switch to the AUTO position will put the pan/tilt into Random Scan.
