9.6.3 Two-wire connection to an Eclipse Median system frame
To connect your HelixNet Party-line system to an Eclipse Median, using a two-wire connection:
1. On the HMS-4X Main Station, configure the Module Settings for the Two-wire interface module.
For the procedure, see
5.6.2 Configuring a Two-wire interface module.
Note:
Check that the two-wire module is configured for Clear-Com systems (the default) and enable
Auto-nulling. Auto-nulling helps to reduce echo while talking on a two-wire audio system.
2. Physically connect the HMS-4X Main Station to the CCI-22 dual-channel party-line interface
module.
The CCI-22 may be fitted:
• Directly to an Eclipse Median.
• An interface frame (such as the IMF-3 or IMF-102), connected to the Eclipse matrix.
Tip:
For more information about installing and using the CCI-22, see the CCI-22 Manual, or go to:
Powering the connection:
You must power the connection between the HMS-4X Main Station and the CCI-22 using either a
dedicated power supply (such as the PK-7, PS-702, or PS-704), or a powered Encore Main
Station (such as the MS-702 or MS-704).
Tip:
For more information about the PK-7 or PS-70x power supply devices from Clear-Com, see
Connecting the systems:
There are two parallel DB-9M Interface I/O connectors on the CCI-22. Because the two-wire
module on the HMS-4X Main Station features two 3-pin XLR connectors, a crossover CAT5 cable
is required to make the connection. For more information about wiring the connection, see:
• 9.6.2 Quick reference: Two-wire connection to Eclipse.
• The CC1-22 Manual.
