Up to ten beltpacks, in full duplex (simultaneous talk and listen), may communicate with each other over a Ethernet network. In fact do to the flexibility of the BTR-24 system, wired beltpacks connected via a hub to a network could communicate to a BTR-24 connected to the same network. This base station could then be connected wirelessly to other TR-24s operating in wireless mode.

Set-up

Below are instructions for the set-up and operation of a TR-24s connected via an Ethernet backbone.

1.Prior to use the TR-24 should have their battery packs fully charged. Refer to the “Battery Charging Instructions” near the end of this section.

4.Plug headsets into the TR-24 beltpacks.

5.Power-up the TR-24 beltpacks in wired mode. The wired mode is entered by holding the <1> button down as the unit boots. Once a beltpack was booted in a mode (wireless, wired, master wireless), the beltpack will always boot in that mode until the user sets a different boot mode.

•The power light should immediately light solid.

•After 20 seconds a beltpack voice prompt will announce “wired” in the headphone (The "wired" announcement will be followed by the software version within the unit.).

•Audio channel one’s light will activate indicating communication has started.

Beltpack Audio Channels - Press the <1> button for audio channel one only. Press the <2> button for audio channel two only. Press both <1> and <2> buttons simultaneous to select both. Use the talk button to select between enabling / disabling the headset microphone path. The channel light(s) will blink if the microphone path is disabled. The light(s) will be solid if the microphone path is enabled. See table below for talk modes:

2.Plug the TR-24’s external power supply into an AC outlet if desired. If external power is not desired then run off internal battery.

3.Connect the TR-24(s) to each other via an Ethernet backbone. Use category 5e or better Ethernet cables that are wired to standards T-568A or T-568B (Most all Ethernet cables are built to these standards).

NOTE: Either straight through or crossover Ethernet cables my be used. The beltpack and base station automatically detect which type is connected.
