1 Introduction
HARVEY RC4 is a freely programmable end-user wall remote control for Ethernet networks.
It is compatible to all members of the HARVEY family of audio and media control matrixes.
The remote control is supplied exclusively via Ethernet (PoE).
For user interaction the HARVEY RC4 has one rotary encoder with an integrated push button
and four LED backlit push buttons to control audio levels, invoke DMX commands, or recall
scene settings. The four push buttons can be labelled. A LED light ring indicates fader
positions. All LEDs are of RGB type and can be programmed with an individual colour
scheme and brightness. HARVEY RC4 is completely supported by HARVEY Composer
allowing a seamless configuration of complex media scenarios where several remotes in
parallel control a system of HARVEY audio matrixes.
Two HARVEY RC4 models exist:
1. HARVEY RC4-EU: RC4 in a plastic housing compatible for mounting into standard
round European flush-mounted boxes with a diameter of 60 mm.
2. HARVEY RC4-US: RC4 with a metal faceplate compatible for mounting into standard
2-gang North-American flush-mounted boxes.
This manual shows how to wire, assemble and label both the HARVEY RC4-EU and the
HARVEY RC4-US model.
For programming and integration into your audio or control projects please refer to the
HARVEY Composer manual.

4 Quick Installation
For full HARVEY RC4 configuration and operation following items are required:
1. Minimum one HARVEY RC4,
2. HARVEY Composer (v2.1.4.0 onwards) installed on a Windows computer,
3. Either
a. an Ethernet switch capable of delivering Power over Ethernet (PoE) according
to IEEE802.3af Class 3 (12.95 W) or
b. a regular (non-PoE) Ethernet switch in combination with an Ethernet PoE-
Injector which is capable of delivering PoE according to IEEE802.3af Class 3
(12.95 W),
4. a HARVEY audio matrix (any HARVEY NxM model).
Wiring
The following three diagrams show all wiring options for HARVEY RC4.
Option 1 – Flexible network cable with power provision from a switch with PoE capability
attached to the RJ45 connector of the RC4.
Option 2 – Flexible network cable with standard Ethernet switch without PoE capability and
power provision from a PoE Injector attached to the RJ45 connector of the RC4.
Option 3 – Stiff network cable with power provision from switch with PoE capability attached
to the terminal block of the RC4.This option does not apply to the RC4-US model.
Operating Manual HARVEY RC4
10/20
A switch-based power provision (i.e. endspan PoE) is possible both for RJ45 wiring option 1
and for the terminal block wiring option 3.
An injector-based power provision (i.e. midspan PoE) is possible for the RJ45 wiring option 2
only.
Stiff Network Cable (e.g. CAT7)
For stiff network cables the RC4 offers wiring option 3 – a connection to the internal 4-pole
terminal block which accepts stiff wires only. This option does not apply to the RC4-US
model. Following cable assignment is valid for the terminal block:
Status LED
As soon as the RC4 is powered and connected to the network it indicates its status by the
bottom LED of the light ring.
Yellow: RC4 is in self initialization mode1.Blue: RC4 has network link and waits for
pairing with a HARVEY device.
It leaves the before mentioned two states as soon it is actively paired with a HARVEY project
which has been programmed with HARVEY Composer. Please refer to the HARVEY
Composer operating manual for integrating HARVEY RC4 into your HARVEY projects.
1Among other things during initialization the RC4 waits for a physical network link. A physical link to
the Ethernet network and data activity are indicated at the RJ45 interface on the rear side of the RC4,
for both the RJ45 and terminal block wiring option.

5 Instructions for Mounting, Labelling and Wiring
PROCEDURE 1: Follow these instructions forwards for disassembly in case you want to mount
a RC4 to a wall panel or you want to label the four push buttons. Assembly is done in the
reverse order.
For disassembly of the
RC4-EU housing first you
have to demount the rotary
knob.
For this you need a hexagonal
screwdriver (1.3 mm), which is
delivered together with the
RC4.
Insert the screwdriver into the side hole of
the rotary knob. Find the screw and unscrew
it just one to two turns to avoid losing the little
grub screw.
Pull the button off the endless encoder shaft.
It needs some force – be patient, wobble the
knob a little bit, then it can be removed.

…continuation of PROCEDURE 1 (disassembly of upper and lower housing shells):
Use a cross-headed screwdriver to remove
the screw next to the encoder shaft which
joins the upper and lower housing shell.
Divide the upper and lower shell of the RC4
housing.
Finish of PROCEDURE 1 (disassembly of upper and lower housing shells).
For labelling the four push buttons proceed with PROCEDURE 2 on the next page.
For mounting the RC4 onto an EU flush-mounted box (UP60) and a flexible network cable
with a RJ45 connector follow PROCEDURE 3.
For attaching the RC4 to a stiff network cable coming from the wall follow PROCEDURE 4 first
and then proceed with the second half of PROCEDURE 3 for flush-mounted box mounting.

PROCEDURE 2: Proceed with the following steps for labelling the four push buttons of the
RC4.
Remove the screw joining the printed circuit
board and the front shell of the housing.
Remove the front shell from the printed
circuit board.
Remove the light guide bodies by gently
pulling them from the push buttons.
Remove the transparent caps from the light
guide bodies.

…continuation of PROCEDURE 2 (labelling push buttons):
Good results can be achieved by printing the
labels on transparent foil sheets and cutting
them with a knife or scissors.
Put the label into the transparent cap and the
cap onto the light guide body.
Gently put the light guide bodies back onto the
push buttons.
Finish of PROCEDURE 2 (labelling push buttons).

PROCEDURE 3: Mounting onto an EU flush-mounted box and connecting a flexible network
cable coming from the all to the RJ45 connector.
The RC4 is designed for mounting into a
standard 60 mm European flush-mounted box
(UP60).
A box’s depth of 60 mm is recommended.
Take the lower shell, insert the network cable
through the RJ45 opening and mount that
configuration onto the flush-mounted box.
Plug the RJ45 connector into the RJ45 on the
upper shell’s side.

…continuation of PROCEDURE 3 (wall mounting with flexible network cable with RJ45):
Put the left side of the upper shell’s slots over
the two keys of the lower shell.
Proceed with the instructions of Procedure 1 in
reverse order to re-assemble the housing.
Finish of PROCEDURE 3 (wall mounting with RJ45).

PROCEDURE 4: Connecting a stiff network cable without RJ45 coming from the wall to the
terminal block connector.
Strip off appr. 50 mm of the stiff network
cable’s mantle.
This is the result of de-mantling the cable.
Gently divide the four wire pairs with their
shield foil.

Operating Manual HARVEY RC4
18/20
…continuation of PROCEDURE 4 (wall mounting with stiff network cable without RJ45):
Cut the foils – do not cut the shield-mesh!
Turn back the shield-mesh and wind it
around the end of the four wire pairs.
Cut those four wires which are not required
for a 100BaseT wiring (i.e. wires 4, 5, 7 and 8
according to the standard T-568A/B
numbering rules) – only following wires are
required:
Wire 1: Tx+ / DA+
Wire 2: Tx- / DA-
Wire 3: Rx+ / DB+
Wire 6: Rx- / DB-
Wire pairs 1 / 2 and 3 / 6 should be twisted.
Lead the stiff wires from the rear side of the
lower housing shell through the designated
whole.
Use a long-nosed plier to lead each stiff wire
into the correct terminal during gently
pushing down the referring white window with
a screw driver.

…continuation of PROCEDURE 4 (wall mounting with stiff network cable without RJ45):
This is the result of the cable installation to the
terminal block.
On the rear side of the lower shell push the
shield-mesh of the stiff network cable under the
cable clamp and fasten the screw tightly.
Put the left side of the upper shell’s slots over the
two keys of the lower shell.
Proceed with the instructions of Procedure 1 in
reverse order to re-assemble the housing.
Finish of PROCEDURE 4 (connecting stiff network cable to terminal block).
