Description of Features

The RC210 provides 3 radio "ports", each of which may be operated independently or in unison with the others. With simple

programming, each port can be configured as follows:

A Standalone Repeater

A signal received on that port's receiver is retransmitted out that port's transmitter. Each port has its own independent hang

timer, timeout timer, 10 courtesy tones and dedicated DTMF decoder, so you may operate one RC210 to control 3 independent

repeaters. On command, any port may be tied to any other port for linking purposes.

Half-Duplex Or Full-Duplex Link

If a port is configured as half-duplex, a signal received on that port's receiver is NOT retransmitted out that port's transmitter.

Through DTMF commands, the receiver's COS (and CTCSS signal, if so equipped) and audio is routed to either - or both - of

the other ports. This is useful for linking to other sites or connecting your system to an EchoLink©, IRLP© or other such system.

Control Receiver

Because of the RC210's ability to control any Port from any other Port, there is no need for a special, dedicated control receiver

port. By using the right combination of Macro Functions, you can easily and quickly disable or enable any function the RC210 is

capable of performing. For example, you have a repeater on Port 1 and a link on Port 2.

Remote Base

Any port can be used for a remote base - a half-duplex (or simplex) radio connected to the repeater system that allows the

repeater users to remotely operate on a different frequency/mode/band than the repeater. Frequency, transmitter offset and

CTCSS may all be remotely programmed over the air. The RC210 also supports control of Kenwood mobiles that provide for

DTMF control through their microphone port. The complete list of supported remote base radios can be found in Appendix A.

Regardless of how you configured a port, each one provides all signals needed for the radio connected to it (COS, transmit and

discriminator audio, CTCSS encode and decode). You have a choice of either DB9's or RJ45 modular jacks as your radio port

connector. COS and CTCSS decoder input polarity is selectable through easy-to-use push-pin jumper blocks, so the RC210 can

accommodate just about any radio available.

Audio gating is provided on each radio port so you may obtain audio directly from the receiver's discriminator without the worry

of finding a source of gated audio in the receiver. De-emphasis is also provided on each port. However if you don't need de-

emphasis on any particular port, it's a simple matter to change a jumper (no soldering required) and obtain "flat" audio (20 hz to

15Khz) throughout the audio chain. The use of low-noise JFET operational amplifiers ensures good gain, high input impedance,

and very clean audio.

DTMF tones are normally muted on ALL ports however you can turn off muting on a port-by-port basis. This allows for passing

DTMF tones out a link.

Any port can be used for entering DTMF commands, even programming commands for other ports. Since each port has its own,

dedicated DTMF decoder, a command can be entered from any port uninterrupted regardless of activity on other ports.

Many timers are provided, such as repeater transmitter hang time, timeout, ID intervals, how long the cooling fan should remain

on after the transmitter unkeys, and more. These timers are remotely programmable.

The RC -210 incorporates true human speech. A custom, repeater oriented vocabulary is provided for use in IDs, alarm and

other controller messages. In addition, the on-board digital voice recorder allows the recording of up to 20 custom recordings

which may also be used in these messages.

All parameters of the controller can be remotely programmed using DTMF. Timers, control codes, port configuration and

messages can all be changed at the whim of the repeater owner. All the command codes may be programmed to your own,

special and unique code. This makes the RC210 very easy to incorporate into existing systems without users having to relearn

code structures. All parameters are stored in non-volatile EEPROM, so your settings are retained even if the controller loses

power.

The controller's programming is protected from unauthorized access by the use of 3 different 5-digit secret passcodes - one

used for each port. Each port may be programmed independently without affecting the others.

The RC -210 represents all numbers in standard decimal notation. In other words, you don't need to worry about converting

programming parameters to hexadecimal notation before actually programming anything.

There are 7 buffered general-purpose digital outputs also provided that can be used to remotely control devices at the repeater.

Alternately these outputs can be programmed to perform other tasks. With the addition of simple external shift registers, these

can be expanded to 64 outputs.

The controller uses flash memory to store its operating program. Just plug your computer into the RC -210's programming port

and you can upload updates in minutes.

A Word About Identification

The RC210 provides an intelligent algorithm for ID sequences to minimize disruption to ongoing repeater communications, while

providing entertaining messages and meeting FCC requirements for repeater identification.

If the repeater has not been in use for a period of time and a new user keys the repeater, the controller will ID after he unkeys

with one of the three Initial ID messages (these messages automatically rotate). This message could say "Welcome" followed by

the callsign, or some other such "friendly" message.

After the Initial ID is finished, the Pending ID timer starts to run. After it times out, it looks to see if any repeater activity has

occurred since the Initial ID played. If there has been activity and no user is currently talking, the Pending ID is played.

Otherwise, the controller waits for no user and then will send the Pending ID message.

Hardware Reference

Power

The RC210 requires anywhere from +11.5 to +15 vdc at 60 ma. This voltage source should be clean, filtered DC. Power

connection is made through a Phoenix power connector and the mating plug is included with the RC210. There is no need to

worry about using a fuse, as the RC210 is protected by an on-board, self-resetting fuse. Once the overload condition is cleared,

the fuse will automatically reset.

Table 1 shows the connections.

Note: Pin 1 is closest to the DB25 I/O connector

There are two grounds provided to prevent digital noise from appearing on the audio channels - digital ground and analog

ground. It is important that these two grounds are kept separate and run directly to the negative (-) terminal of the power source

(BOTH GROUND CONNECTION MUST BE MADE). The battery backup pin may be used to insure the controller remains

powered during power outages. This will allow the RC210 to continue to function and the on-board real time clock will not lose

time. If this connection is made, the RC210 automatically and instantaneously switches power.

Carrier Operated Switch

The signal from the receiver which indicates that a signal is present is called COS. The RC210 can accommodate a COS signal

that presents either a logic high (5 to 15 volts dc) or a logic low (< .8 vdc) when a signal is present. Table 2 shows the settings of

the corresponding jumpers.

Table 2

Jumper Description Pins 1 & 2 Pins 2 & 3

JP1 Port 1 CTCSS Active Low Active High

JP2 Port 1 COS Active Low Active High

JP3 Port 2 CTCSS Active Low Active High

JP4 Port 2 COS Active Low Active High

JP5 Port 3 CTCSS Active Low Active High

JP6 Port 3 COS Active Low Active High

The RC210 presents a high impedance on its logic inputs (>10K ohms), you can choose a point in the receiver without concern

that the controller will "load it down". These specifications apply to all logic inputs used with the RC210.

Sub-Audible Tone Decoder

In addition to the COS signal, the controller can optionally use a signal derived from an external CTCSS (continuous tone

controlled squelch switch) decoder on each port. If this option is used, the controller can be commanded to require users to use

sub-audible tone with their transmissions on that port. The RC210 accomodates either a logic high (5 to 15 vdc) or a logic low (<

.8 v) when a valid tone is detected. This is set using the jumper settings, as shown in Table 2.

Push-To-Talk

The controller provides a solid-state switch closure to ground, capable of sinking 500 ma from a positive source at a voltage of

up to 100 vdc. This should accommodate just about any radio on the market.

Receiver Audio And De-Emphasis

Audio from the receivers needs to be supplied to the controller and is controlled by a crosspoint switch matrix under

microprocessor control. Each receiver's audio is routed to the appropriate transmitter(s) as needed.

The audio circuitry in the controller allows for a variety of signal levels and impedances. It is capacitively coupled, which means

that a dc level may be present on the signal provided. The level is internally adjustable, so a fairly wide range of levels is

acceptable, but for best results the level should be between .5 and 2.5 volts peak-to-peak. This should accommodate just about

any receiver.

The input impedance is high (>10K) , so that audio may be picked off anywhere inside the receiver without loading problems.

Supplied audio does not need to be de-emphasized nor gated, as the controller takes care of this for you. If you choose a point

inside the receiver that is already de-emphasized, you can remove the jumper to disable the controller's de-emphasis circuitry.

In this case the controller's audio input stage will provide flat audio. Table 3 shows how to configure these jumpers

Table 3

JUMPER PORT # DE-EMPHASIS FLAT

JP7 1 ON OFF

JP8 2 ON OFF

JP9 3 ON OFF

Transmitter Audio

Audio is supplied from the controller to the various transmitters. This audio consists of receiver, speech and tone audio,

switched and mixed under control of the CPU in the controller.

The audio is high level and medium impedance, so it's easy to find a good place to inject it into the transmitter. The high level

minimizes hum and noise pickup and may be knocked down at the transmitter if necessary. However the level is internally

adjustable and this option should rarely be necessary. The output is capacitively coupled, so you connect it without concern of

dc voltage at the point of connection to the transmitter.

DTMF Decoders

Each port has its own dedicated DTMF decoder, with each decoder being connected full time to its respective port. DTMF may

be entered at any time from any port without regard to activity on the other ports. The controller will store the commands and act

on them in the order they were received. Each decoder may be configured to require CTCSS in order to function or not require

CTCSS.

Indicator LEDs

LED's are provided for monitoring all the Port's COS, CTCSS, PTT and Valid DTMF signals. These can be useful for setting up

and verifying operation of these various signals and are marked directly on the PC board. In order to reduce power

consumption when the LEDs do not have to be powered up, the push-on jumper on JP13 may be removed. If mounting the

RC210 in a cabinet, a switch may be connected to JP13 to allow the operator to conveniently turn the LEDs on and off as

needed.

Auxiliary Audio Inputs

These inputs allow you to add external audio devices without using one of the radio ports. For example, you could connect a

weather receiver to one and be able to monitor weather conditions on demand. If the weather receiver has an output that is

triggered when a S.A.M.E. Alert is issued, you can use one of the Alarm inputs on the RC210 to automatically trigger one (or all)

of the transmitters.

The Auxiliary Audio Inputs do not provide any means for adjusting their level, so you must provide this capability in your

interface between your audio source and the RC210. The impedance of these inputs is approximately 20K and the level should

be adjusted to approximately 100 mv peak-to-peak.

Expansion Connectors

There are several pin header connectors on the PC board which allow for easy access to several data lines in the RC210.
