RS232 Connection & Signals
AMP Located Centrally*
AMP can be positioned at a central point, such as a rack, and connected to the transmission
device via a short patch lead.
Managed Lip Sync Set Via PC
As mixing analog audio and digital video can often cause sync issues, the AMP
contains settings and software to overcome such difficulties.
*ARC not supported in this instance
RS-232C, EIA RS-232, or simply RS-232, refers to the same standard defined by the Electronic Industries Association
in 1969 for serial communication.
DTE and DCE
DTE stands for Data Terminal Equipment. A computer or control system is DTE and connects to Data Communication
Equipment, or DCE such as an AMP, matrix or modem.
DTE equipment typically feature a Male Connector, while DCE contain a Female Connector, although that is not always
true - a simple way to confirm is to measure Pin 3 and Pin 5 of a DB-9 Connector with a Volt Meter, if a voltage of -3V
to -15V is achieved, the device is DTE. If the voltage is on Pin 2, then the device is DCE.
Note: The result for a DB-25 Connector is reversed (Please refer to DB-9 to DB-25 conversion table)
