The LRD41C21/LRD41C22 Series Legacy® receiver is designed for
use with our LWM41 wall mount. Standard features include 64
presets, 8 inputs for preset alarms*, and 1 alarm output. Choose
from fixed speed or variable speed models for 24/120/230 VAC
applications.
The LRD41C21 Series receiver is for use with fixed speed Legacy
pan/tilt models PT780P, PT780P/PP, PT780SL, PT780SL/PP, PT78024P, PT780-24P/PP, PT780-24SL, and PT780-24SL/PP. The LRD41C22
Series receiver is for use with variable speed pan/tilt models PT780VS, PT780-VSSL, PT780-VS/PP, and PT780-VSSL/PP.
The LRD41C21/LRD42C22 Series is compatible with either
Coaxitron
®
control systems utilizing standard 15-bit or extended 32bit command protocols or Pelco serial RS-422 control systems
utilizing D- or P-type protocols.
Also available is the LRD41TLC test local control module which
allows on-site testing of Legacy system functions. Simply plug the
TLC into the connector on the receiver and you're ready to test the
system functions. The TLC module operates on +5 VDC supplied by
the receiver and controls these functions: iris open/iris close, focus
near/focus far, zoom telephoto/zoom wide, tilt up/tilt down, and pan
left/pan right.
