Page 5: Introduction
This will save you a lot of confusion and frustration, as it should answer most of your questions. The RLC-1 repeater controller consists of one repeater port, one linking port, four analog voltage inputs, four logical (dry contact) inputs, and five MOSFET output drivers. The repeater and linking ports can be configured to require combinations of COR and PL inputs for access. -
Page 6: Limited Warranty
Contact Link Communications for more information. What Link Communications will not cover: 1. Too much voltage to the controller. The RLC-1 operates at +11V to +15V, negative ground. 2. Damage to the controller by lightning, accident, or incorrect power hook-up. -

Page 8: Setup And Interfacing
The numbered steps cover the basics, through connecting your radios and adjusting the RLC-1. After that there is information concerning the other input and output features of the RLC-1: the serial interface, the logical output and input lines, and the analog input lines. -

4 volts, or open), or an Active low COR (Goes from a voltage greater than 4 volts, to a ground, or goes from an open to a ground). The input impedance of the RLC-1 COR input is 10KS and it is diode clamped with internal pull-up resistors. This allows it to handle input voltages of up to 40 volts without damage to the controller. -
Page 10: Connecting Your Transmitters To The Rlc-1
Step #5: Connecting Your Transmitters to the RLC-1 Transmitter PTT: - The RLC-1 produces an active low PTT signal (ground when PTT is active). This output is buffered with an open drain type driver capable of sinking 150mA. There is a built in 30V zener clamping diode to protect the PTT MOSFET from the high voltage spikes that can be caused by interfacing to a PTT relay coil. -
Page 11: Adjusting The Rlc-1 Controller
Locate connector J10 on the RLC-1 (it is above the 2 voltage regulators). This test bus will provide the signals that we need to adjust the inputs on the RLC-1. In order to maintain audio deviation during channel switching, all of the receiver inputs must be set to the same level. These signals can be measured with an oscilloscope or an AC voltmeter. -
Page 12: Serial Port Interfacing
Serial Port Interfacing The RLC-1 has a serial terminal port for interfacing to any serial device, i.e. packet and serial terminal. This allows the user to monitor, control, and program all facets of the controller. The serial terminal carries highest priority for access and programming of the RLC-1. There is an 8 digit password needed to log on to the serial port of the controller, ensuring the security of the system. -
Page 13: Operation And Programming Over The Serial Port
The RLC-1's serial port gives the controller the ability to communicate with the world over a digital radio link. The RLC-1 has a security key of 10 characters that must be entered properly in order to have the RLC-1 communicate with your computer terminal. The syntax of... -

Page 16: Logical Latched Output Lines
Logical Latched Output Lines The RLC-1 offers 5 logical control lines for site control. These 5 latched control lines are power MOSFETs in "open drain" configuration. Because the output lines are open drain, the user will not measure any voltage on the output lines, only an open or a ground. In order to check the condition of the control lines, a meter set to resistance will be needed. -
Page 17: Logical Input Line
Logical Input Line The RLC-1 offers the user 4 logical input lines. These lines recognize an open/ground input change. These lines are internally pulled up to +5 Volts and zener diode clamped to 5 Volts. This allows direct interface to higher voltage inputs that do not exceed +40 Volts. The application to site users is great: door open/closed magnetic contacts (See Figure #3a), local site controlled switches, and site power monitoring relays (See Figure #3b). -

Page 30: Main And Link Access Mode
The RLC-1 offers the user the ability to select from three modes. These conditions are based on the state of the COR and PL (CTCSS) inputs. The RLC-1 will accept either an Active High COR (COR goes from ground, or 0 Volts to a point above 4 Volts), or an Active Low COR (COR goes from a voltage above 4 Volts, to ground, or 0 Volts). -

Page 32: In Depth Command Description: C009
The RLC-1 has the ability to mute the audio when DTMF digits are being entered. When muting is enabled, the RLC-1 will begin muting as soon as a valid DTMF digit is detected (a short "bleep" is inevitable) and continue muting as long as at least one digit is entered each second. This allows multiple tones to be muted without each one causing a "bleep."... -

This command allows for offset adjustment of the analog lines. This command is used to calibrate the information read in by the RLC-1. If a known voltage or current is not read correctly by the RLC-1 (is off by a few degrees or volts), that input can be calibrated by changing the offset associated with that analog line. -
