RS-232 (Serial) Routing
The Multicast system features two ways of managing RS-232 command signals:
Type 1 - Fixed Routing:
A static fixed routing for distributing two-way RS-232 commands between a Multicast Transmitter to one multiple
Receivers (Fixed Routing). Fixed routing can be left static between two or more products as a permanent connection
for the transfer of RS-232 control data, this is configured using the Fixed Routing menu of the ACM.
Type 2 - Guest Mode:
Allows the RS-232 connection of a device to be sent over the IP network (IP / RS-232 command in, to RS-232 out). Type
2 Guest Mode gives third party control systems the ability to send an RS-232 or IP command to the ACM and an RS-232
command to be sent out of a Receiver or Transmitter as a result. This IP to RS-232 signalling, allows the third party
control system to have control of as many RS-232 devices as there are Receivers and Transmitters, from the network
connection to the ACM.
There are two ways of enabling Type 2 - Guest Mode:
1. Using the ACM web-GUI from the Transmitters and Receiver Action tabs.
2. Via the command set as detailed below. The command to configure the connection is: IN/OUT xxx SG ON
RS-232 Guest Mode Connection from a Third Party Control System:
When using Guest Mode on multiple devices within a system, we would recommend turning Guest Mode on and off
when required. This is because a serial command being sent into the ACM will be passed to ALL devices that have
Guest Mode enabled.
1. To open a Guest Mode connection between the ACM and an IPxxxUHD-TX or RX unit the following
command must be sent via IP or RS-232:
INxxxGUEST
OUTxxxGUEST
Example:
2. Once a connection is established, any characters that are sent from the ACM will be transmitted to the
connected Transmitter or Receiver, and vice versa.
3. To close the connection send the escape command: 0x02 (02 in Hex). If using Telnet, the connection can also
be closed by pressing: CTRL + B.

Connect to TX xxx in Guest Mode from the ACM
Connect to RX xxx in Guest Mode from the ACM
Transmitter ten is ID 010, meaning 'IN010GUEST' will allow bi-directional Serial / IP
commands to be sent between the ACM and Transmitter 10.
