NCS-C411 Audio & PTT Delay Module
The NCS-C411 Trunking Delay Module is a “must have” when connecting trunking system radios to the NCS-C250., NCS-C251, NCS-C150 or NCS-C151. When installed between any of the devices and the trunking radio, the NCS-C411 delays the transmitted audio and PTT release while the trunking system acquires a clear channel. This allows the operator to transmit immediately after pressing the PTT without loosing syllables or words at the beginning of the transmission. The NCS-C411 is easily installed and requires 12 VDC @ 250mA. The interface cable to the appropriate switcher and power cable are provided. Radio Interface Cables are sold separately. Setup is simple and requires selecting the proper acquisition delay time for your trunking system. Available delay times are 0 ms, 50 ms, 100 ms, 200 ms, 400 ms, 800 ms, 1600 & 3200 ms. These values are switch selectable on the front of the unit.
The C411 can be provided on a 1U 19" rack panel. The panel will accommodate up to 3 units.
NCS-C412 Dual Audio & PTT Delay Module
The NCS-C412 Trunking Delay Module is a dual module version of the NCS-C411. It operates just like the C411 except it is configured to provide audio & PTT delay for two radios. The audio delays, identical to the C410 values, are switch selectable on the front of the unit.
The C412 can be provided on a 2U 19" rack panel. The panel can accommodate up to 3 units.
