Serial Connection Configurations

The following procedures set configuration parameters in the Configuration/Service Software (CSS)
using a serial connection.
4.4.3.1

Setting the Device IP Address and Pairing Number in CSS

Prerequisites: Obtain the required credentials information (local service account password and
elevated privileges password) to configure the site devices before proceeding. The user credentials
information includes both the current and new credentials. Without the current credentials, access to
the device or to the user credentials is denied. See
Troubleshooting on page
NOTICE: Setting or changing the device IP Address causes the SNMPv3 configuration and
user credentials to automatically reset.
Procedure:
1 Connect to the device using Configuration/Service Software (CSS) through a serial port link. See
Connecting Through a Serial Port Link on page
2 From the menu, select Tools → Set IP Address/BR_CM Pairing Number.
NOTICE: If the device is not in a voting or simulcast IP only topology, the menu item is
shown as Set IP Address/Box Number.
The Set IP Address and Base Radio/Comparator Pairing Number dialog box appears or the
Set IP Address and Box Number dialog box appears.
3 In the Device IP Address field, enter the device IP address. Click Set Device IP Address.
4 In a voting or simulcast IP only topology, enter the device pairing number. Click Set BR/CM
Pairing Number.
5 Click OK to close the dialog box.
6 Click Reset to initiate a hardware restart.
SNMPv3 user credentials reset to their factory default values.
7 Click Close to close the dialog box.
8 To reconfigure the SNMPv3 user credentials, see
Credentials in CSS on page
4.4.3.2

Pairing To a Comparator

When operating in a voting, multicast, or IP simulcast configuration, base radios must be paired to
comparators using the BR/CM Pairing Number. The BR/CM Pairing Number for the base radio and
comparator is used to create an IP multicast group that allows the base radio and comparator to talk to
each other. The base radio listens for messages that the comparator sends to establish an IP
connection with all the paired base radios. When the base radio receives the message from the
comparator, it extracts the comparator IP address from the message and uses it to send received voice
and data back to the comparator.
Communication from the comparator to the paired base radio always uses a multicast IP address.
Communication between the paired base radio to the comparator always uses a unicast IP address.
