NCS-C411

Audio & PTT Delay Module

The NCS-C151 is a two radio repeater with the same features as the NCS-C150 except this unit has an on board Audio & PTT Delay circuit to provide delay to one trunked radio. If two trunked radios are used, Audio & PTT Delay is provided by a separate NCS-C410 or NCS-C411 module.


The Delay circuit provides a user selectable audio delay to accommodate inherent delays seen in trunked systems between receipt of PTT and assignment of channel. Delays of 0, 50, 100, 200, 400, 800, 1600 & 3200msec are selectable.


The NCS-C151 has a small form factor of 2.1" x 4.1" x 4.7" (HxWxD) and operates from 9-14VDC for use in any vehicle or fixed location.


The unit is provided with mounting brackets that enable securing the unit on top of or under a mounting surface. The form factor also accommodates easy mounting to a 19" 2U rack panel.

Internal Settings

 The NCS-150 has internal settings for operating mode selection:


 COR+: High going carrier detect signal from radio.

 COR-: Low going carrier detect signal from radio.

 VOX: Received signal detection from voice signals being received.

 LOW-HANG: Reduces the hang time when in VOX Mode.

 TX Level: Controls are provided to adjust transmit audio level of each radio.

 REC level: Control for recording of combined audio.

Accessories

Radio Cables: NCS provides cabling to interface most commercial and amateur radios with the NCS-150 & NCS-C151. Cables can be provided for mobile as well as portable radios. The cables come in a standard length of 6 feet, however custom lengths are available.

Audio & PTT Delay Modules: The C410, C411 & C412 Delay Modules provides a user selectable audio delay to accommodate inherent delays seen in trunked systems between receipt of PTT and assignment of channel. Delays of 0, 50, 100, 200, 400, 800, 1600 & 3200msec are selectable.

AC Power Supply: A variety of power supplies are available for use with the C150 & C151.

The NCS-C150 is a two (2) radio repeater for cross band or in-band operation. (In-band operation requires the same RF proximity and Antenna considerations as any other in-band repeater). This flexible unit works with conventional, trunked and P25 radio systems; analog or digital. Rapid deployment, simple configuration, easy operation and no training required make this an ideal solution for occasional deployment in mutual aid situations as well as day-to-day interoperability operations.


The unit contains an automatic gain control circuit so setting of each radio´s receive audio is not required. Either radio can use COR of either polarity or VOX for the Busy signal.


Interface cables are available for nearly any radio including PTT phones.


The NCS-C150 has a small form factor of approx 4 x 4.75 x 1.25 inches and operates from 9-14VDC for use in any vehicle or fixed location.


The unit is provided with mounting brackets that enable securing the unit on top of or under a mounting surface. The form factor also accommodates easy mounting to a 19" 1U rack panel.
