9.5.3 Two-wire connection to the DX210
To connect your HelixNet Party-line system to the DX210 basestation (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
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. On the rear panel of the DX210 basestation, 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
basestation (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
Connecting the systems:
Use standard microphone cable to connect the two systems. 3-pin XLR connectors are located:
• On the HMS-4X Main Station two-wire interface module.
• On the back panel (rear) of the DX210 basestation.
Two 3-pin XLR connectors (one male, one female) are provided for each of the two
intercom channels (
IC1 and IC2)
on the basestation
[ ].
4. On the front panel of the DX210 basestation, press the SELECT button for the connected
intercom channel (either IC1 or IC2).
The 2-W (two-wire) LED next to the SELECT button is lit
green
.
Note:
If power is not detected at the connector, the 2-W LED is lit
red
. No audio can be transmitted
between the systems. When the HMS-4X Main Station is powered, power is supplied to the
connection and the 2-W LED is lit
green
.
