System Configurations

The Wolf1000 can be configured via P.C. Software .  The repeater programming software communicates via the computer's Com1 port through a serial cable to a DB9 connector attached on the face of the PCF1 Controller.

The Ctcss control is programmable and has the capability of separate tones for each repeater or the control card can be programmed to regenerate any of the 39 standard Ctcss tones decoded by the receiver. (I.e. Community link repeaters).  Any repeater can be programmed to be inactive until activated with DTMF ( I.e.  Hot Standby repeaters for emergency use, which are activated when needed and turned off when not in use.)

Control Description

Carrier only -  When the controller card decodes a 'Carrier', it activates the repeater's transmitter and routes the audio from the receiver to the transmitter.

Carrier + Ctcss -  The repeater is activated by the presence of both Carrier and a Ctcss tone.  The Ctcss tone can be selected as either a fixed tone or selected as any valid Ctcss tone.  When this option is selected, the valid tone is regenerated.

DTMF Access + Carrier -  The repeater requires valid DTMF access code to be turned "On".  When the Valid DTMF code is received, the repeater will be activate on receipt of a carrier present at the receiver.  The repeater can be de-activated by re-sending the DTMF Access code.

DTMF Access  (Carrier + Ctcss) - DTMF Access code is required to turn on the repeater and afterwards requires both carrier + a valid Ctcss tone to activate the repeater.

Wolf1000D Operation - Drop/Link Configuration

The Drop/Link can be configured to be a 'Normal" link and drop configuration, in which, the Drop is active and acts like a normal repeater with the Link inactive until it is activated with a DTMF Command or a valid Ctcss tone.

If the Wolf is programmed for the DTMF Access, when a valid DTMF code is received, the cross connections are done to the Link repeater occur and a connect tone is sounded through both the link and drop to indicate that the Link/Drop is activated.

Activity on the Drop (depending upon programming, Ctcss or carrier or both) is then routed to the Link and activity on the Link side is routed to the Drop.

The 'Normal' Drop/Link configuration can be used like a 'Hub and Spoke' system which will allow for other Links to connected together.  DTMF signaling would be required from the mobile to turn on the Link/s when using a complex system.

If the Drop and Link are connected and there is no activity for a preset programmable time, the Link will shut off, sending a Disconnect tone.  If there is continual activity and the Time Out Timer is exceeded (I.e. a mobile transmitter is on continually), the Link will disconnect and if the activity was from the Drop, the Drop's transmitter will be turned OFF until the offending transmitter's signal is gone.

The Drop/Link can be configured to be a "Hot" Drop and Link allowing the cross connection between the Drop and Link to be always active and not require a DTMF command code to enable or disable the Link.  In the case where the Time Out Timer is exceeded, the Link and Drop transmitters are both disabled until the continual carrier disappears.

Wolf1000T Operation - Link/Drop/Link Configuration

The Link/Drop/Link repeater configuration allows signals by the Link to be passed through to the opposite Link.  This configuration is normally used when connecting Link networks together and the link is 'hot'.  The Link will not pass any audio on the drop unless it is cross connected by command or programmed to be a 'Hot' Drop with the Links.

Wolf1000T Operation - Wye (Y) Configuration

The Wye (Y) configuration is a special 'Hot' Link to Link with the audio going in only one direction to the Drop and the audio from the opposite Link is routed to the the Wye(Y) Link, but not to the Drop.

The Wye (Y) configuration would be used in a Dispatch to Mobile communications, where ONLY the Dispatcher traffic is heard by the mobile.  This application may be used in systems in which the vehicle to vehicle communications is not desired.

On a rural radio telephone system, the Wye (Y) configuration would be used to provide a one way voice security for the mobile.  When a mobile talks to the telephone, the drop will not pass the audio to the mobile.  The mobiles will only hear the telephone side of the conversation.

Wolf1000T Operation - Delta Configuration

The 'Delta' configuration is a special 'Hot' Link to Link with a Drop.  The audio on both links are heard on the Drop, however, the Drop receiver audio is not routed to the Drop's transmitter.  This configuration would allow traffic from area to area through Links and all traffic to be heard.
