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 or multiple
Receivers (Fixed Routing). Fixed routing can be le 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 ACM200.
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 ACM200
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 ACM200.
There are two ways of enabling Type 2 - Guest Mode:
1. Using the ACM200 web-GUI. See page 20 for enabling Guest Mode on a Tranmsitter and page 23 for enabling
Guest Mode on a Receiver unit.
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
o when required. This is because a serial command being sent into the ACM200 will be passed to ALL devices that
have Guest Mode enabled.
1. To open a Guest Mode connection between the ACM200 and an IPxxxUHD-TX or RX unit the following
command must be sent via IP or RS-232:
INxxxGUEST Connect to TX xxx in Guest Mode from the ACM200
OUTxxxGUEST Connect to RX xxx in Guest Mode from the ACM200
Example: Transmitter ten is ID 010, meaning 'IN010GUEST' will allow bi-directional Serial / IP
commands to be sent between the ACM200 and Transmitter 10.
2. Once a connection is established, any characters that are sent from the ACM200 will be transmitted to the
connected Transmitter or Receiver, and vice versa.
3. To close the connection send the command: ACMCLOSEGUEST
Please note: When the ACM200 is in GUEST MODE the web-GUI is disabled.
