RS-232 (Serial) Bi-Directional Pass-Through
The Video Over IP products feature bi-directional RS-232 pass-through for control of products using serial commands.
There are multiple methods for distribution of RS-232 using the ELAN Video Over IP solution which include:-
1)
Type-1 Redirection Mode:- 1-to-1 routed RS-232
A link is programmed that creates an open connection between ANY Video Over IP product in the system (Transmitters or Receivers).
Once established the RS-232 commands can be sent in either direction between products.
Multiple links can be created between Video Over IP products for additional independent product control.

Type 2 Guest Mode:- Telnet/IP conversion to RS-232
This method of control converts a Telnet/IP control command into an RS-232 command. A link is programmed that creates an open
connection between an EL-4KPM-VIP-CTRL control module and any EL-4KPM-VIP-TX or RX (Transmitters or Receivers) product in the
system. Telnet/IP commands are sent into the EL-4KPM-VIP-CTRL from a third party control solution. This is then converted into an
RS-232/serial command for control of third party products.
