Overview

Compatibility

The 3031 Crosspatch is designed to be compatible with a wide range of VHF and UHF transceivers. The VHF or UHF transceiver must have:
a Tx audio input
an Rx audio output with constant volume (that is, its level is not dependent on the volume setting)
an active low PTT input control signal
a squelch (or carrier detect) output control signal
See the documentation provided with your VHF/UHF transceiver to check that these
NOTE
capabilities are available, or consult with your VHF/UHF dealer. Some transceivers require software configuration to enable these signals.

DTMF-capable VHF/UHF transceivers

The method of entering a DTMF command varies across the range of DTMF-capable VHF/UHF transceivers. When you enter a DTMF command, you should follow the process required for your VHF/UHF transceiver. In the instructions provided in this guide, only the DTMF command to be entered is provided, not the method of entering the command.
See the documentation provided with your
NOTE
VHF/UHF transceiver to determine how it transmits DTMF signals.

Setting up the Codan HF transceiver

Channel names

You can use a DTMF-capable VHF/UHF transceiver to command the Codan HF transceiver connected to the crosspatch to select a specific channel. However, only numeric digits can be entered into the DTMF-capable VHF/UHF transceiver, and you must include a leading zero if the channel is less than 10.
This does not restrict all of the channels in your Codan HF transceiver to having numeric-only names like 01, 02, and so on. In particular, if you already have established channel names with which your operators are familiar, these can still be used with some small adjustments made to the setup of the Codan HF transceiver connected to the crosspatch.
NOTE
Any channel names in your existing networks that have no common naming convention (such as Codan 01, Night 02, Day 03), may be used with the crosspatch. In this case, it is recommended that the channel names contain different numeric sequences. To use these existing channels you can use the default channel prefix command (see page 31, The default
channel prefix).
The only restriction placed on channel names is that they must include a 1 or 2-digit numeric sequence in the name.
If you have grouped channel names in your existing networks (such as Codan 01, Codan 02, Night 01, Night 02), these channels are easily used with the crosspatch. To use these existing channels you must define a specific channel prefix (see page 32, Defining a channel prefix).
For information on grouping entries see the

documentation provided with the Codan HF transceiver.
Setting up the Codan HF transceiver

The RS232 [15way] Startup entry

The Codan HF transceiver connected to the crosspatch has an entry in the Control List that enables you to set up attributes for the port to which the crosspatch is connected. These attributes are read on startup. In an NGT series Transceiver this entry is called RS232 15way Startup. In the 2110 Manpack Transceiver this entry is called RS232 Startup.

The default channel prefix

If you do not enter a channel prefix command as described below, the Codan HF transceiver connected to the crosspatch selects a channel based on the numeric sequence in the channel name. It ignores any alpha characters that appear in the name, and removes any leading zeros from the numeric sequence.
If you have channels that contain different alpha names but the same numeric sequence (such as Codan 1, Night 01, Day 1), and a command is received from the crosspatch to select channel 01, the Codan HF transceiver connected to the crosspatch selects the channel named Codan 1. This selection is based on the number 1, and Codan 1 is selected because it is listed alphabetically before Day 1. The channel named Night 01 is ignored in the selection process.

Operation with a DTMF-capable VHF/UHF transceiver
The mute status during scanning of any remote HF transceivers may be set to Selcall since any DTMF call commands made from the DTMF-capable VHF/UHF transceiver will perform a Selective call to the address supplied.
Operation with a VHF/UHF transceiver that is not capable of DTMF operation
If you are using the crosspatch with a VHF/UHF transceiver that is not capable of DTMF operation, you may choose to set up the Codan HF transceiver connected to the crosspatch to remain on a specific channel.
36 Crosspatch 3031 User Guide
Setting up the Codan HF transceiver
A VHF/UHF transceiver that is not capable of DTMF operation cannot command the Codan HF transceiver connected to the crosspatch to select a specific channel. It can only command the Codan HF transceiver to select the default channel by pressing PTT three times within 1.5 s. For information of setting the default channel see page 38, Setting
the default channel.
Any remote HF transceivers listening for VHF/UHF communications can be set to scan, however the Mute Scan status of these transceivers must be set to Voice or Scan for voice, since the VHF/UHF transceiver making the call cannot make a Selective call to a remote HF transceiver unless such a call is set up in the XP 99 entry of the Codan HF transceiver connected to the crosspatch (see page 40, Entries in the
Address List of the Codan HF transceiver connected to the crosspatch).
To set up the Codan HF transceiver connected to the crosspatch to remain on a specific channel:

Self address of the Codan HF transceiver

The self address of a Codan HF transceiver is the unique identifier for the transceiver that is used by other HF transceivers to make a call to it.
If a remote HF transceiver needs to be called directly by a DTMF-capable VHF/UHF transceiver using DTMF command *aaaa##, the self address entered into the remote HF transceiver must be numeric and between 3 and 15 digits long.
If your existing HF communication network of transceivers uses other alphanumeric address formats, you do not have to change these. Instead, you can set up the Address List of the Codan HF transceiver connected to the crosspatch with entries that will automatically make a call to the specified HF transceiver with the alphanumeric address. When you make a call via a DTMF-capable VHF/UHF transceiver using one of these entries in the Address List, you need to specify the entry number corresponding to the HF transceiver that you want to call using DTMF command *ee##. For information on setting up the Address List see page 40, Entries in the Address List of

Using commands to control the crosspatch

The operation of the 3031 Crosspatch is fully integrated into the operation of the Codan HF transceiver. Making and receiving calls at the Codan HF transceiver is no different from normal operation. For information on using the Codan HF transceiver see the documentation provided with the transceiver.
The 3031 Crosspatch may also be controlled from a third­party VHF/UHF transceiver. This transceiver may or may not be capable of DTMF operation.
See the documentation provided with your VHF/UHF transceiver to determine how it

NOTE
transmits DTMF signals and at what spacing each tone should be entered. See page 77,
Specifications for optimal tone and pause
durations.
When entering DTMF commands into a VHF/UHF transceiver you should wait to hear an appropriate tone sequence from the crosspatch before entering the next DTMF command.
If you enter DTMF commands while holding PTT on t he handset of the VHF/UHF transceiver, you should enter the first tone within 3 s of PTT being pressed. There should be less than 1 s between tones.
