Before You Begin
There are several paths to optimization; the items listed in this section will play a significant part
in determining the ideal path.
2.1
JPS Channel Profiles
The JPS Channel Profiles embedded in each Z-series product speed the setup process by
automatically setting the Z-Series device’s radio interface configuration options to those listed
in the
Application Note
that accompanies the cable. These settings are correct only when using
the associated JPS cable.
Note:
Channel profiles and application notes provide a good starting point, but a channel may
require additional adjustments. For this reason and for general convenience, users can also create
and save their own channel profiles.
2.2
Local Handset and/or USB Headset
The Handset included with the ACU‑Z1, or a properly configured USB Headset can be helpful
because it allows a known baseline interface (the handset or headset) to be compared to a (yet
unproven) interface. For example, assume a problem is encountered when interfacing two radios
to the Z-Series device, or interfacing a radio to a JPS RoIP backhaul channel. Use the handset or
the headset to
connect to each of the channels individually in turn
. This will quickly identify the
problematic channel.
Recommendation:
It is best to initially set up and optimize each channel while it is connected to
the handset or headset only, and then cross-connect the other two (now fully proven) channels to
each other.
Note:
For a list of headsets, refer to the table
Optional Equipment - Not Supplied
in the unit’s
Installation and Operation Manual
.

Radio Interface Cables
2.3.1
JPS Radio Interface Cables
JPS provided Radio Interface Cables were designed by JPS Systems Engineers who investigated
the radio’s analog interfaces, then designed an appropriate interface between the radio and the
JPS equipment and verified it in the lab. Some interfaces are simple, others are not so. Some
require DC blocking capacitors or unusual level-setting networks. The JPS cables include a small
circuit board that properly interfaces with radio hardware for hundreds of different radio makes
and models. For these reasons, JPS cables are always the best option for interfacing a radio to the
ACU‑Z1, RSP‑Z2, or other JPS gateways.
The cable should easily connect to the radio; many are built by splicing a cable manufactured for
the specific radio to the appropriate signal lines on the JPS cable.
