characters over a PSTN line for control purposes. Can also be used with FM radio.
DSP
Digital Signal Processing (or Processor).
Hangtime
Sometimes called VOX Hangtime, Receive Hangtime, or Transmit Hangtime, a hangtime causes a
device to maintain the effect of audio presence for a brief period even without the actual presence
of audio. Hangtime is often used to prevent brief pauses in input audio from unkeying an attached
transmitter during the pauses. It may be applied to input audio to provide consistent audio to
multiple outputs (VOX Hangtime or Receive Hangtime) or, theoretically, applied to an output
audio to solely effect a single output (Transmit Hangtime).

human speech and notably not by tones, noise, or other non-speech audio. It is typically used as a
gating mechanism for audio –when speech is detected by VMR, this allows the speech audio to
flow into or out of a device. VMR is particularly useful with noisy audio signals such as HF because
VMR will ignore most static and white noise.
VoIP
Voice Over Internet Protocol. Protocol for delivering voice communications over IP networks.
Most network-phone providers (such as Vonage), use VoIP.
VOX
Voice Operated Xmit (Transmit), or Voice Operated Switch. A form of audio presence detection
based on sound presence and volume. It is typically used as a gating mechanism for audio –when
sound exceeds a VOX threshold, this allows the audio to flow into or out of a device. The sound is
not restricted to voice only.

limited to a multi-site enterprise, for example, or accessible to the public (e.g. the internet).

Z2 Controller Operations Manual
Interoperability Now 1-1 Z2C Installation and Operation Manual
1Overview
The Z2 Controller creates a scalable interoperability system that is easily managed via its
straightforward, browser-based Graphical User Interface (GUI). Tying together the wide range
of audio communications devices remotely interfaced to it, the Z2 Controller enables audio
sharing with all JPS RoIP (Radio over IP) products, such as the NXU‑2B, the ACU-2000, the
ACU-M, etc., as well as with JPS’ new Z series of products, including the RSP-Z2 and the
ACU‑Z1. Features like simplified dispatch capability, monitoring by non-dispatch channels, and
IP recorder integration provide enhanced functionality, making the Z2 Controller an adaptable
solution to a diverse array of interoperability and communications uses.
1.1 Scope
This Installation and Operations Manual provides a description, specifications, and configuration
and operating instructions for the JPS Interoperability Solutions' Z2 Controller.
This section provides some essential background information that will assist in understanding
the capabilities of the Z2 Controller unit and the basic elements that make up an interoperability
system that it controls. The Z2 Controller will also be referred to as the Z2CTM.

Z2 Controller Operations Manual
Z2C Installation and Operation Manual 1-2 Interoperability Now
1.1.1 Important Definitions:
COR: A signal that indicates when a radio (or other type of communications
device, such as an ACU ‑ Z1 or an RSP-Z2) is receiving a valid audio signal.
PTT: A signal that tells a radio (or other communications device) to transmit the
audio signal being sent to it.
Full-Duplex Communication System: Users can simultaneously talk to and
listen (for example, a standard telephone call).
Simplex or Half-Duplex Communication System: Only one system user can
be heard at a time.
Interoperability Net: Communications link consisting of disparate devices (such
as radios of different frequencies, telephones, VoIP phones, etc.) connected
together, similar to a conference call.
The following paradigms are essential in understanding the basic operation of an interoperability
system.
•If multiple communications devices are engaged in an interoperability net, whenever one
device detects active COR (valid audio input), that audio, along with a PTT signal, is sent
to all other devices in the net to be transmitted.
•If any device in an interoperability net is half duplex (such as are almost all radio
systems), then all communications must be half duplex.
1.2 Z2 Controller Basic Overview
Using the Z2 Controller, Operators easily configure and manage up to 80 remote virtual
streaming channels and an optional USB headset using the intuitive GUI, which provides the
following functions:
•Easily create and manage interoperability nets that cross-connect various voice
communications systems that are interfaced to the Z2 Controller. Once they are
connected, an Operator simply manages all resources using the Z2 Controller GUI.
oVirtual JPS Bridge channels offer a means for remote devices, such as RSP‑Z2
Dual-Channel Interoperability Gateways and MCC Desktop Consoles, to
connect/stream audio to the Z2 Controller to expand interoperability coverage and
functionality. Optional encryption licenses are available for added security.
oVirtual JPS RoIP channels provide a mechanism for streaming audio from a
remote source –such as a radio connected to an NXU‑2B or a DSP‑2 card on an
ACU 2000 –to the Z2 Controller using JPS RoIP. They may also be used to
interface to a Push-to-Talk application such as JPS VIA. Optional encryption
licenses are available for added security.

Z2 Controller Operations Manual
Interoperability Now 1-3 Z2C Installation and Operation Manual
•Use the versatile Dispatch feature for one- and two-way communications.
oA Dispatcher can place any number of the resources interfaced to the Z2
Controller into an easy-to-use Dispatch Area for one-way listening (monitoring)
or two-way communications (dispatch).
oIt does not matter whether these resources are concurrently engaged in an
interoperability net.
•Monitor one or more channels independent of net/Dispatch activity.
oMultiple resources can be set up to monitor other channels.
oChannels may be monitored by more than one Monitoring resource.
•Record all channels within a net, or within the Dispatch area. This provides system
operators the ability to stream conversations directly to an IP recorder for non-evidentiary
recordkeeping and playback.
•Manage users/permission, set up and verify Z2 Controller network configuration, and
configure channels easily using the browser-based GUI and its built-in help text.
1.2.1 Interoperability and Dispatch
The main purposes of the Z2C are to create interoperability nets that link multiple voice
communications systems together, and/or to Dispatch to those systems.
The following block diagram shows a small sample interoperability system that will be used to
illustrate various Z2C system functions.

Z2 Controller Operations Manual
Z2C Installation and Operation Manual 1-4 Interoperability Now
The example system has eight different voice communications channels: Five are different radio
bands/frequencies, another is a SIP Phone, and the remaining two consist of a pair of JPS VIA
PTT over Cellular Talkgroups. These channels are all interfaced to the system via four RSP-Z2
units using Bridge channels and one NXU-2B that uses JPS RoIP. Note that each of the JPS VIA
Talk Groups requires a dedicated RSP-Z2 channel, which is interfaced to the JPS VIA server and
adapts the JPS VIA channel into a format recognizable to the Z2C.
Each of the channels is configured on the Z2C, which can accept connections on up to 80 virtual
streaming channels, using JPS Bridge or JPS RoIP data stream protocols. By setting up channels
on the Z2C to accept these connections, users can manage streaming audio to and from connected
remote resources. (E.g. Putting channels in nets, dispatching to/from channels).
•JPS Bridge channels are available on newer JPS products, such as this unit as well as
other Z-series products, and on some third-party devices, such as the MCC Desktop
Console, that have implemented the JPS Bridge Channel Protocol.
•JPS RoIP (Radio over IP) is a JPS proprietary protocol that sends voice plus radio control
signals over an IP network. With only a few exceptions, JPS RoIP channels are available
on most JPS radio interoperability gateway products.
•While JPS’ newer products have both JPS Bridge and JPS RoIP streaming channels, it is
best to use Bridge channels as they carry additional helpful data such as Audio Priority.
Furthermore, JPS Bridge channels support streamlined integration with other JPS systems
and with select third-party products.
Operators browse to the Z2C GUI to create and dissolve any interoperability nets. Its audio
engine handles all audio mixing.

2.7 Power Source
The power supply included with the unit operates from input voltages and frequencies of 100 to
240 VAC, 50 - 60 Hz. Other standard “laptop-type” supplies can be substituted, but must provide
a nominal +12 VDC, and be capable of at least 1.5 amp output. Note that the power supply
included in the Z2 Controller accessory kit is a premium version with a 1500V isolation
transformer.
2.8 Safety Precautions and Procedures
The Z2 Controller is operated by a +12 VDC power supply and therefore any high-level power
supply voltage exists only on the AC input side of thepower supply. Standard precautions relative
to 115 or 230 (nominal) AC wiring applies.
Note: The Z2 Controller contains no user-serviceable components and
there is no reason to disassemble the unit.
Return the Z2 Controller to the factory for servicing.
2.9 Maintenance
The Z2 Controller contains no user-serviceable internal components, and no hardware
maintenance is required.
Consult the JPS Interoperability Solutions website for firmware updates. Refer to Firmware

3Web-Based Configuration
This section provides instructions on how to log in to the Z2 Controller’s Graphical User
Interface (GUI) and perform initial network configuration. User types and permissions, channel
configurations, and other setup information is addressed in other sections.
The Z2C is standards-compliant and therefore supports standards-compliant web browsers,
including Internet Explorer (must be IE 10 or higher), Edge, Firefox, Chrome, Opera and Safari.
It is always best to use the most current version of any web browser.
Note that due to ongoing upgrades and enhancements, the device’s web pages may not be
identical to those shown in this manual. This should not affect functionality.
3.1 Initial Log In - Set up IP Address and Subnet Mask
As with any device with a static IP address, it will be necessary to set up the Z2 Controller to
operate on the LAN where it is to be deployed. The first step is to log in using the unit’s factory
default IP address of 192.168.1.200, with a default subnet mask of 255.255.255.0.
Connect the Z2 Controller via Ethernet cable directly to the Ethernet Port of the computer that
will be used to access and configure it. Set the computer to a static IP address of 192.168.1.xxx
(where xxx is a number between 2 and 199) and a subnet mask of 255.255.255.0.
Plug in the unit’s power supply and turn the unit on via its front panel power switch. The Z2
Controller’s front panel LEDs will flash while the unit boots up (approximately 90 seconds).
Follow through to Section 3.3 to get instructions for logging in and changing the network
configuration parameters.
3.2 Log In
Upon browsing to the Z2C’s IP address, the login screen will appear. The default name and
password are both “su” for superuser with the superuser’s full-capability permission set.
Note: For best security, it is strongly advised to change the default
username and password before putting the unit in service, however it is
not required to continue setup. See Section 4 for instructions about
adding/changing user names and passwords, as well as associating
appropriate permission sets with individual users.

3.3 Network Configuration
To change network settings, click on “Settings” and then “Network” –the following dialog box
will be available for changing system parameters as shown below. (Note: The settings shown are
not the system default settings).
Figure 3-2: System Network Setting Entry Screen
After entering the new address and subnet mask, write them down for safekeeping (though the
unit can be interrogated for its current settings, as explained in the next section). Then press
Submit. The unit will reboot tointegrate the new settings. Next, log in again at the new IP address.
3.3.1 IP Address Determination and Change VIA USB port
If unable to access the Z2 Controller because you’ve forgotten its IP address and other network
settings, the front panel USB port can be used to retrieve the needed information. Plug a thumb
drive into the port and cycle the power. After power-up, the unit will store several files on the
drive; these include diagnostic log files plus a short text file that lists the unit’s network
information. Most important will be its IP address and subnet mask. After the unit is fully
rebooted the USB drive will be unmounted and can be unplugged. Use the USB drive’s LED to
indicate when it has completed downloading the log files.
Note: If you edit the parameters ofany of these files, the Z2 Controller may
experience unexpected behavior.
On the USB drive, open the file named “network-info.txt” It will list the parameters shown in
the figure above. If changing the network settings, follow the instructions in the Initial Log In
Section 3.1, using the IP address in this file to access the unit.

current version can be found by clicking the version number in the lower right of the Z2C Home
