19.6.2 Quick Reference: Two-Wire Connection to DX210
19.6.3 Two-Wire Connection to the DX210
To connect your HelixNet Party-line system to the DX210 base station (Main Station), 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 Configuring a Two-wire interface module
Note: Check that the two-wire module is configured for Clear-Com systems (the
default) and run Auto-null. Auto-nulling helps to reduce echo while talking on a two-
wire audio system. You must run auto-null every time you change the cabling.
2. On the rear panel of the DX210 base station, ensure that the Clear-Com / RTS button is set
to Clear-Com mode (the out position).
3. Physically connect the HMS-4X Main Station to one of the two intercom Channels on the
DX210 base station (Main Station).
Powering the connection:
You must power the connection between the systems 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 dedicated power supply devices (PK-7 or PS-
70x devices) from Clear-Com, see
