Each access port includes input connectors and looping ouput connectors for the audio and RS422 digital control lines.
See below.
The audio cable is a conventional twisted pair shielded cable; 24 gauge or larger recommended. The audio connectors are
3-pin Phoenix connectors. The audio amplifier has a high (10 K Ohm) input impedance to allow bridging a number of
amplifiers across the line and requires a 1 volt audio signal to drive the amplifier to full output.
The digital control cable (RS422) requires a minimum of 5 conductors: RX+, RX-, TX+, TX- and Ground. Each data pair
must be on its own twisted pair: one pair for RX+/- and one pair for TX+/-.
When wiring from the RS422 adapter to a column or combining multiple arrays together on the same network, all data con-
nections are wired in PARALLEL: RX+ to RX+, TX+ to TX+ and so on.
Recommended RS422 data wire type: CAT5E wire is acceptable, or for shielded type, Belden 9729 has been tested by
Renkus-Heinz up to 800 meters. When using very long wire lengths, a terminating resistor may be necessary.
The data connectors for the digital control line are a standard 9-pin DB-9 connector and a 7-pin Phoenix connector. These
are also in parallel and either can be used. Since RS422 has no pinout standard for a DB-9 connector, pay special note to
the pinouts described below.
FAULT RELAY WIRING
A Fault Relay is an optional Iconyx feature . The Fault Relay when installed provides an indication (a dry signal contact) of
a failure or malfunction in any one or all of its associated D2 amplifier’s eight DSP/amplifier channels. The dry contact pro-
vides a means of triggering an associated remotely located fault alarm panel (not provided by Renkus-Heinz).
The Fault Relay contacts are rated for an operating voltage of a maximum of 28V DC or AC at a maximum current of 1
amp. This is considered to be a “dry contact”. The contact is completely isolated from circuit or chassis ground. Under no
circumstances is the contact to be used for 120V AC line operation, any voltage higher than 28V AC or DC or any applica-
tion connected either to the hot or neutral side of the AC line.
