The ITC-100 is a half-duplex system, which means only one person can speak at a time, as audio is carried over a single wire both ways. It does not support full-duplex or party-line communication.
The ITC-100 only supports wired communication.
Max Cable Length
You can run 5-pin XLR cables between the base station and belt-pack up to 200 Meters.
Please see this support article for more information.
Number of Conductors in Cable
The ITC-100 intercom cable utilizes 5 conductors and a foil shield. Datavideo offers pre-made cables in a variety of lengths. CB-3 (20 Meters or 65ft), CB-4 (50 Meters or 164ft) and CB-76 (76 Meters or 250ft available only in the USA).
The 5-pin XLR cable conductors are 20 gauge wire.

Compatible 3rd Party Headsets
Many headsets will work with the ITC-100, but some professional sets have 4-pin XLR connectors. The Datavideo CB-8 adapter allows you to connect a 4-pin XLR headset to the ITC-100SL belt pack. The wiring schematic for the CB-8 is available in this support article.
