control, and DTMF (telephone) control. Other devices can be used for controlling the R165A as long 
as they provide the proper signaling. 

Control by Time

The R165A can be directly connected to 

MFR#

 R153 program timers so that program signals 

can be switched according to time schedules at the broadcast point or headend. The switch-timer 
interface would look something like the following graphic.

Control by LAN

The R165A can also be easily controlled by anyone on the local network with a web browser. This application requires 

interfacing the R165A with a network remote control, 

MFR# 

model R190A. The connection scheme is very similar to the 

one used with the R153 above and would look like the following graphic.

Control by DTMF

The R165A can also be operated by one of the 

MFR#  

DTMF remote controls that allow switch 

operation by DTMF signaling from a standard dial-up telephone (model 6002) or by a dry 600 ohm 
audio line (model 6003). Connections for this application are shown in the following graphic.
