Wireless: Interconnecting Multiple Tempest Base stations together without using Master Mode
Question: Can a user operate multiple Tempest systems in the following manner: One channel of the system is connected to a Clear-Com MS-702 main station (channel A to all Tempest bases). The other Tempest channel is used only for all available beltpacks on all Tempest systems (no connection to MS-702 channel B). Can the user use Master Mode on only the second Tempest channel?
Answer: Tempest systems cannot be in Master mode when connected to a CC PL main station, Tempest will kick out of master mode as it is only meant to be used on a Tempest configuration with multiple base stations where no Clear-com PL is used. In Master Mode the Tempest base set to this mode supplies PL power to the remaining Tempest base PL channels remaining in the daisy chained configuration. Master mode cannot be set for individual PL channels on the base station.
In order to get a second channel (in essence an ISO beltpack channel) with all beltpacks from multiple base stations the base stations 2nd PL channel should be daisy chained together so that all base beltpacks can hear each other on that channel in 2-wire mode. To make this work the Tempest 2-wire PL channel must be powered by the MS-702 base, in order to do this a 3-pin XLR cable with pin 3 disconnected can be used (this cuts the audio from the MS-702), this will still supply +30Vdc via pin 2 and provide a ground via pin 1 to the Tempest "C" 2-wire PL channel so that the user has a 2nd channel that only talks to all three Tempest base beltpacks. The wired PL audio is not introduced in / out of the daisy chained Tempest systems 2nd isolated channel.
In addition to the above mentioned change with the powered PL cable to the 2nd IC channel on the linked Tempest base stations the user will have to construct a 200 ohm termination plug using a 3-pin XLR connector to an used 2nd IC channel jack, the termination should be a 1/4 watt 220 ohm resistor soldered between pins 1 and 3 of the XLR connector. This will provide the necessary audio termination on the 2nd channel.
