CONNECT SYSTEMS INC. 1802 Eastman Ave. Suite 116 Ventura, Ca. 93003 Phone (805) 642-7184 Fax (805) 642-7271 Model TP-154 Shared Repeater Tone Panel USER'S INSTRUCTION MANUAL S/W rev. 3.01 Manual upgraded January 1997 Made in U.S.A. Copyright (C) 1997 By Connect Systems Inc.
IMPORTANT NOTICE Your TP-154 is equipped with CTCSS Trak... , a revolutionary software decoding algorithm that gives the TP-154 unbeatable tone sensitivity and talk down resistance. This TP-154 is supplied with the ability to decode either the standard 38 EIA CTCSS or 50 CTCSS tones tones and 104 DCS codes. To select the number of tones, use JP-7. With JP-7 installed, you decode 38 tones. With JP-7 removed, you decode 50 tones. Consider carefully before you jump into the 50 tone version.
THE CONNECTIONS Two connections must be made to the receiver and three to the transmitter. Use shielded wires with the shields at each end connected to chassis ground. (The rear panel barrier strip terminals labeled "GND" are chassis ground). We recommend using spade type crimp-on connectors for ease and reliability. Connect the center wires as follows: RX AUDIO: The audio input terminal should be connected directly to the receivers discriminator (de-modulator) output.
VALID: This is an open collector NPN transistor output that is used to let a companion Model 8200 Full Duplex Interconnect know when DCS or CTCSS is valid. The transistor is normally on, but is turned off during the interval that a DCS or CTCSS code is valid. This output is only used when using the TP-154 in conjunction with a CSI Model 8200. +12 VDC: Connect to a source of 12-14 VDC. The TP-154 is reverse polarity protected, so a polarity mistake will not damage your TP-154.
ADJUSTMENTS P1 PREAMP: The PREAMP control is used to match the audio level from your receiver to the TP-154. To adjust, a signal containing 100 HZ CTCSS with about 600 HZ deviation must be applied to the receiver. Adjust the PREAMP control until a level of 3V P-P is observed at TP-1 using an oscilloscope. If an oscilloscope is not available TP-1 should read 1V RMS using a VOM. This completes the adjustment of the PREAMP control.
JUMPER STRAP OPTIONS JP-1 De-emphasis strap. If you have connected to the discriminator output, JP-1 should be installed. If you have connected to a source of flat (already de-emphasized) audio such as the high end of the volume control JP-1 must be removed. If JP-1 is improperly strapped the audio will not sound proper and DTMF will not decode properly. JP-2 Output level strap. The audio output is selectable in two ranges. With the strap installed, the audio out is 0-1 volt.
PROGRAMMING THE TP-154 The TP-154 can be programmed with DTMF from a radio or service monitor, or by plugging any DTMF telephone set into the rear panel RJ-11 modular jack and using the telephone DTMF keypad. There are three programming modes: 1. PER USER PROGRAMMING: This allows you to make programming selections on a per user basis. See TABLE 2 for User Number vs Tone/Code 2. GANG PROGRAMMING: This allows you to quickly program all 154 user slots to the same setting.
In Local Programming Mode the front panel PROGRAM LED is steady on (non-flashing) and the transmitter remains off. Each time you make a programming entry the results are displayed on the front panel display (rather than a DTMF transpond) for validation. Command Syntax: When programming, you will enter programming sequences such as *nnn#09#mm#. (This particular command programs a users first character of CW ID). Or, *nnn#01#J#. (This command enables or disables a users courtesy beep).
The top bold line identifies the item you may wish to program and the syntax to use for programming followed by the syntax to use to read this parameter back to either the front panel display if programming locally or to your CD-2 if programming from a remote site. The subline tells you everything you need to know to program this particular parameter. The first information lets you know the allowable range for mm and that if you can enter zero to disable this parameter altogether.

CW ID characters and corresponding mm values may be obtained from Table 1. The entry immediately following your message must be 38 which means "end of message".
SQUELCH TAIL LENGTH *000#20#mm# *000#20* mm 00-99 (0-99 Ms - 1 Ms/step) [mm = 0 = 0 Milliseconds] Set to 0 for minimum tail. Only used if the receiver has a poor squelch and can stop word clipping by adding squelch delay. If there is a tail noise when set to 0, it is caused by slow squelch response in the receiver. The TP-154 does not add any more tail than is inherent to the receivers squelch if set to 0. CTCSS/DCS HOLD DELAY *000#21#mm# *000#21* mm 3-99 (.3-9.9 Sec's - .

INTERPRETATION OF CD-2 DISPLAY DATA When the *nnn#00* command is sent from the remote programming location, the TP-154 responds with a lengthy string of DTMF data to load the CD-2 memory with all data relative to user nnn. Upon completion of the string the CD-2 begins displaying all of the user programming for the user (nnn) which has been requested. The left two digits identify which data is displayed and the right two digits show the actual data.

SPECIAL TEST MODES 1. Test Transmission with any DCS or CTCSS: Occasionally it may be handy to have the repeater send a carrier with any DCS code or CTCSS tone you wish for various test purposes. First enter the program mode as previously discussed. Then enter this sequence: *nnn#99# Where nnn is the user number that corresponds to the tone or code you want the TP-154 to transmit. See Table 2. The test transmission will last as long as you remain in program mode or until you enter a * or a new command.
DEFINITION OF TERMS Courtesy beep: A brief tone at the end of a users transmission that lets the party you are speaking with know that it is their turn to reply. Barge in: An attempt to cut in by a user who does not have the DCS/CTCSS code of the user currently using the system. Reserve tone: A tone in reserve tone status will bring up the repeater but audio will not pass. Cross tone: Converts a users input DCS or CTCSS to another DCS or CTCSS as desired.
Hog: A user or user group that monopolizes airtime. Hog Penalty: This feature is designed to give the system manager some control over airtime hogs which may drive other customers away. In order to use the Hog Penalty feature it is necessary to understand how it works. There are three timers which can be individually set in the global programming. These are ... HOG MONITOR: This timer sets the maximum talk time a subscriber may use without incurring a no talk penalty.
CIRCUIT DESCRIPTION The incoming audio is buffered, de-emphasized and amplified to the amount set by the PREAMP control by input op amps U1. The audio then proceeds to a six pole low pass filter and a six pole high pass filter. The low pass filter U2 removes voice audio and extracts the DCS/CTCSS signal for detection at the adaptive differential comparator. The comparator output is fed to the microcomputer U12 pin 12 for software DCS/CTCSS detection.
