Theory of Operation General Desk Set Overview The L3149B (C200) Advanced Desk Set is a multi-processor design employing state-of-the-art DSP technology to achieve superior performance over typical analog and single-processor designs. This allows for ultimate flexibility in audio processing. The heart of the design consists of U1, the DSP; and U3, the microcontroller. The DSP is responsible for audio processing of receive and transmit audio.
Theory of Operation L3149B (C200) Advanced Tone Remote Desk Set In addition to the transmit audio, data is combined with the transmit audio prior to line-out compensation at U11-3. U10-1 is the line-driver enable for the transmit audio. This provides for a 560-ohm transmit output impedance. Microphone Audio There are three sources for mic audio. These are the internal, handset and audio accessory mic. The microcontroller controls which mic is used based on the source of the PTT.
Programming PC Programming General Description C200 Programming Software (included on No. XAC4000A Programming Bundle CD) is needed to program the features of your equipment. It allows entry of programming data into your PC for transfer to your equipment. The programmed data can be retrieved and edited, and printed in hard copy form for recordkeeping. Hardware/Software Requirements This software is for use on PCs with Windows 95 or higher operating system (not compatible with Vista).
Programming L3149B (C200) Advanced Tone Remote Desk Set Desk Set Parameters Date Format The date may be displayed in one of the following four ways on the desk set: USA: month in numeral format; MM-DD (11-20) European: month in text format; DD Month (20 Nov) USA: month in text format; Month DD (Nov 20) European: month in numeral format; DD-MM (20-11) Clock Format Time may be displayed in either 12-hour or 24-hour mode. If the 12-hour mode is selected, the desk set displays A for a.m.
L3149B (C200) Advanced Tone Remote Desk Set Programming Accessory Mic Bias The mic bias for the accessory connector should be enabled if an electric condenser mic is used for transmit audio. Enabling this parameter allows approximately 4 volts of mic bias to be applied to the accessory mic high input. Accessory PTT Polarity If attached accessory uses a normally open switch for PTT with a closure to ground, this should be set for low active.
Programming L3149B (C200) Advanced Tone Remote Desk Set Type of Interface Select the type of interface depending upon the modules installed in the desk set: Tone Control is available regardless of what hardware is installed. If the relay I/O control module is installed, select E&M with Tone, E&M without Tone, or Local Control. Type of Wire Select between 2-wire and 4-wire interface.

L3149B (C200) Advanced Tone Remote Desk Set Programming Control Parameters Guard Tone Frequency The guard tone frequency is available when the type of interface is Tone or Tone with E&M control. This parameter allows the selection of the guard tone frequency for transmit and receive. Different guard tone frequencies are available for installations requiring them or where paging tones within the guard tone notch are needed. The tone adapter must be configured for the same guard tone frequency.
Programming L3149B (C200) Advanced Tone Remote Desk Set Monitor Frequency/Current When the type of interface is Tone, Tone with E&M, or DC control, this parameter selects the monitor frequency/current used when the monitor button is pressed. Parallel Mute Enabling this feature causes the unit to mute the speaker, not the handset, when a parallel unit is transmitting. This is useful when two or more parallel units are co-located and feedback from one unit to the other is possible.
L3149B (C200) Advanced Tone Remote Desk Set Programming Programmable Buttons The L3149B Desk Set has four programmable buttons. Each may be assigned up to two functions - one with the button alone and one when pressed with the LOCK button. Since there is only one LED per button, the LED only reflects the status of the normal function (programmable button pressed without LOCK). Therefore, certain functions that require the LED cannot be selected under the Programmable Button with LOCK fields.
Programming L3149B (C200) Advanced Tone Remote Desk Set Quick MDC Programming a button for Quick MDC allows two possible uses of the button. The first possible configuration is the selection of manual MDC in the next field. This allows a single button to enter the MDC menu using the programmed call type and allow the operator to select the target ID or alias. The operator may not select another call type. The second possible configuration is the selection of a programmed alias in the next field.
L3149B (C200) Advanced Tone Remote Desk Set Programming Input/Output Relay Table NOTE: This screen only appears if a relay board is present. The relay module consists of four physical relays and four inputs. Relays 1 and 4 are DPDT relays. Relays 2 and 3 are DPST relays. The relays are physically the same part, but I/O limitations of the module limit the number of connections to each relay. The inputs to the module are internally pulled-up and sense closure to ground only.
Programming L3149B (C200) Advanced Tone Remote Desk Set PTT Sense When configured for local control and with parallel units, the operator is not allowed to transmit during the transmission of a parallel unit. This input allows the desk set to sense parallel transmissions and lock-out transmissions until the parallel transmission is over. When this input is asserted, pulled to ground, the TRANSMIT LED flashes. When the input is disasserted, the TRANSMIT LED extinguishes.
L3149B (C200) Advanced Tone Remote Desk Set Programming Monitor When the Type of Interface is Local control, a monitor closure is necessary to place the radio in to monitor mode. This monitor relay is configured as a normally open momentary relay and is asserted when the MONITOR button is pressed and disasserted when the MONITOR button is not pressed. Note that the relay also contains a normally closed contact.
