LBI-38636S Figure 1 - Typical 37-inch MASTR III Stations SAFETY SUMMARY The following general safety precautions must be observed during all phases of operation, service, and repair of this product. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the product. M/A-COM assumes no liability for the customer’s failure to comply with these standards.
LBI-38636S DO NOT SUBSTITUTE PARTS OR MODIFY PRODUCT Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modifications to the product. INTRODUCTION This manual describes the installation and connections for a typical MASTR III station combination. Information provided includes suggested locations and installation of equipment and hardware, interconnection and assembly diagrams, alignment instructions, and troubleshooting suggestions.
LBI-38636S serviceman can easily remove the front and rear doors for servicing. Also, the front and rear air louvers and rear cable outlets must be free of obstructions. Leave a minimum of 12-inches of space on each side of the cabinets to avoid obstructing the louver air vents. With the bottom cabinet in position, secure it to the floor as shown in Figure 2 with 1/2-inch bolts and anchors.
LBI-38636S ELECTRICAL CONNECTIONS AC Power The station will be received with the power cord bundled and stored in the bottom of the cabinet. Remove the twist tie from the AC power cord, unravel and feed the cord through one of the rear cable holes. It may be helpful to remove the grommet from the hole before passing the cord through and reinstalling it afterwards. A separate 15 to 20 Ampere, 120 Vac, 60 Hertz electrical circuit should be provided for the station.
LBI-38636S less populated areas where the phone company has not yet switched to carrier systems. These lines have a fixed amount of loss, which varies with frequency, temperature, from deterioration of splices, and from moisture getting into the cables. When these cables get old, the phone company sometimes applies DC current to improve the joints and lower the line loss. In this case, the line is not usable for DC control. Normally, a +10 dBm test tone can be applied to these lines.
LBI-38636S The telephone company wants to see a maximum three-second level of -13 dBm at the carrier equipment as measured on a modified Western Electric 3-type Noise Measuring Set. The telephone equipment will limit the audio if the signal is above -13 dBm at the carrier input. This does not mean that the maximum that can be applied into the two-wire end is -13 dBm. If the radio equipment is a good distance from the carrier equipment, there will be some line loss.
LBI-38636S 2. The loss of the circuit at 2175 Hz. Do not forget the long-term variation of up to 4 dB more. 3. The requirement that the "Secur-it" burst must arrive at the base station at no less than -20 dBm. Normally, most systems will not crowd these limits. However, if the result is a few dB short, consider adding C-1 conditioning (at an added cost). Resist the natural desire to just turn up the tone sending level as this will cause improper system operation.
LBI-38636S Telephone Company Ordering Information Four-Wire Operation When ordering a telephone line, the following must be considered: 1. Type of circuit: Voice grade, 2-wire termination, for radio control, and tone remote system - send/ receive; voting system - receive only. For examples, refer to Methods 3 and 4 in Table 1, and the associated illustrations showing the different methods (Figures 10 & 11). Jumpers should be installed on P104-2 to P104-3 and P105-2 to P105-3 on the Interface Board. 2.
LBI-38636S Tone Remote Installation Four Wire Tone Remote Jumpers P104 and P105 located on the Interface Board are not required and should be removed. Refer to the sections on TELEPHONE LINE CHARACTERISTICS and LEVEL ADJUSTMENTS for additional installation information. Line connections are made to TB101 or J101 on the T/R Shelf’s Interface Board. TB101 and J101 are connected together and each has the same pin out.

LBI-38636S Table 4 - Normal System Deviation ALIGNMENT PROCEDURE Alignment of the MASTR III base station was performed prior to shipment. The factory assumed the following characteristics: 1. There is no loss or gain for repeated audio deviation. 2. 3. If a remote exists, it is connected to the base station through a telephone line with 10 dB of loss. The base station drives the line output at -10 dBm with nominal receive deviation.
LBI-38636S 4. Repeater Gain • If the station is not a repeater, leave the Repeater Gain pot RG at 1023. • If the station is a repeater, apply an "on channel" RF signal modulated with a 1000 Hz tone at 60% of system deviation to the receiver. • Adjust RG pot for 60% of system deviation (Table 8). Table 6 - System Deviation System Deviation Standard (25 Hz kHz Bandwidth NPSPAC Narrow (12.5 kHz Bandwidth) • 3.75 kHz 3.0 kHz 1.75 kHz Remove the 1000 Hz tone from the Line Input and the REMOTE PTT.
LBI-38636S 5. Line Input Sensitivity and Compression • If not a remote station, set the DSP Line In DLI Pot to 0. • If a remote station, do the following: • • Apply a 1 kHz tone at the average voice audio level across 600 ohms to the line input. (This level is the function tone level, and is usually -10 dBm across 600 ohms, or 245 mVrms. This level MUST be 10 dBm below the "maximum system audio level" even if your actual secur-it tone and function tone are at the same level.
LBI-38636S AUDIO ROUTING AND ADJUSTMENTS Once the T/R Shelf is installed and programmed properly, audio level adjustments may be made for proper system operation. Level adjustments must be made with a handset (LBI-38599). THERE ARE NO MANUAL MECHANICAL ADJUSTMENTS IN THE T/R SHELF. Integrated circuits (IC's) U35 and U36 on the System Board are dual electronic potentiometers that are controlled by the microprocessor. IC U15 on the DSP Board is also a dual electronic potentiometer controlled by the DSP.

LBI-38636N REMOTE CONTROLLER TO STATION CONTROL PANEL ADJUSTMENTS Although audio levels should be considered on a system basis, it is appropriate to set the levels of the remote controller and the control station panel by themselves with reference to the levels required by the transmission path and then connect the controller(s) and station to the path. The transmission path, if it is more than just a simple twisted pair, is usually set up with a "test tone".
LBI-38636S REPEATER PANEL INSTALLATION CSI Model 32 Repeater Panel Use the following information in Table 11 to configure the MASTR III base station when installing the CSI-32 Repeater Panel. 1. Cut the PWB pattern at JP-1 on the T/R Shelf’s backplane 19D902948. 2. Make the following connections between the base station and the repeater panel. Connectors P2, P3, and P5 are located on the backplane. Connection to the repeater panel is made at J3, the rear panel DB9 subminiature "D" type connector.
