RS-232 (Serial) Bi-Directional Pass-Through
IP50HD 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 Blustream Multicast solution which include:
Please note:
Only one method of RS-232 pass-through can be used at the same time. It is not possible to mix different
methods of RS-232 control simultaneously.
1) Fixed Rourting - 1-to-1 routed RS-232
A link is programmed that creates an open connection that is fixed between any Transmitter and Receiver in the
system. Once established the RS-232 commands can be sent in either direction between devices.
Multiple links can be created between Multicast products for additional independent product control.
2) Dumb Redirect Mode - 1-to-many RS-232
A link is opened when a receiver(s) is connected to a transmitter in the system. Once established the RS-232
commands can be sent in either direction between products, allowing a single command to be sent to 1 or many
receivers at the same time i.e. - All displays powered on.
3) 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 ACM200 control module and any IP50HD-TX or RX (Transmitter or Receiver)
product in the system. Telnet/IP commands are sent into the ACM200 from a third party control solution. This is then
converted into an RS-232/serial command for control of third party products.
