When do I use the DA1203RM?
Answer
A Distribution Amplifier is a device that allows you to connect a single video source to multiple display devices, such as monitors or projectors used in presentation applications.
In some cases, you need a

By setting the sync polarity switch to (+) the signal is processed unchanged and the sync polarity of the output signal matches the sync polarity of the DA1203RM. By setting sync polarity to
The SYNC LEVEL switch has two positions — 2V and 4V. Most often a 4V Sync Level is used. This should be considered as default setting. The 2V setting allows compatibility with some older equipment that would be overdriven if a stronger signal were being used.

TROUBLESHOOTING GUIDE | 10 |
We have carefully tested and have found no problems in the supplied DA1203RM unit; however, we would like to offer the following suggestions .
∙Please make sure that input amplitude levels are as follows:
1.Analog signal is less than 1.5V.
2.Sync signal is less than 0.3V.
∙Please check the settings of Sync Level, Video level and Sync Polarity Switches.
∙Please make sure that the proper quality of cables is used. We recommend Altinex made cables for best results.
∙If the problem shows up after continuous usage at higher voltage, higher temperature, higher humidity, or at other extreme environmental conditions, please correct those conditions.
