Pelco Manual C585M-B (11/98) 7
2.0 DESCRIPTION
The Wiretron digital control system operates over a two-conductor cable and con-
trols CCTV equipment such as pan/tilts, enclosures, and motorized zoom lenses
from a remote location up to 10 miles (16 km) away.
Wiretron can be configured to control a single site or interfaced with Pelco video
switching equipment to provide a convenient video/control system with multiple
control sites and/or multiple camera sites.
The Wiretron control system provides up to 15 remote control functions:
1. Pan Left 9. Iris Open
2. Pan Right 10. Iris Close
3. Tilt Up 11. Auto/Manual Scan
4. Tilt Down 12. Aux 1 (Manual Iris)
5. Zoom In 13. Aux 2 (Auto Iris)
6. Zoom Out 14. Aux 3
7. Focus Near 15. Aux 4
8. Focus Far
Functions 1 through 10 are momentary; that is, they are actuated only while the
associated control switch is operated. Function 11 is latching; that is, auto scan
remains on until turned off. Aux 1, 2, 3, and 4 are low power outputs that may be
used to control such things as lights and gates. More auxiliary power output is
available when the controller is used with the AUX2000 Auxiliary Control Box. Aux
1-4 are jumper selectable for momentary/latching operation.
Functions 1 through 10 can be operated simultaneously. Functions 11 through 15
must be used individually, although any one of these functions may be used
simultaneously with functions 1 through 10.
Wiretron provides the following standard functions on a single circuit board and
chassis with integral power supply:
1. Pan/tilt (24 VAC or 120 VAC as ordered from the factory)
2. Zoom lens–zoom, iris, focus with adjustable speed (speed not remotely
controllable)
3. Camera power (24 VAC or 120 VAC as ordered from the factory)
4. An open collector transistor output (latching) for use in the manual override of
an automatic iris control
Wiretron is designed to combat erroneous control and execution by providing the
following protective functions:
1. Simultaneous commands from two different sources are processed to ensure
that manual iris control cannot be inadvertently selected in place of automatic
control.
2. A sustained (20-to-40 second) illegal command condition results in the following:
a. Automatic iris
b. Manual pan
