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 4.6.2 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 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
.
