Network Setting
1. Digital Repeater Mode
If the current channel operation in the repeater mode, if the repeater is
transmitting in timeslot 1, indicator A will glow orange, and if the repeater is
transmitting in timeslot 2, indicator B will glow orange.
2. IP Interconnection Mode
Digital mode supports IP multi-site connection, and may realize interconnection
between IP sites of multiple repeaters. When programming software is used to
configure network services with one master repeater and multiple slave repeaters,
it is required to configure a timeslot to the IP interconnection mode, so that after
the network is connected, services may be transmitted from one repeater to the
other repeaters.
Master Station:
In an IP multi-site connect system, it is permitted to configure only one master
repeater, while other repeaters shall be configured as slave repeater, with IP
addresses registered with the master repeater for IP interconnection.
Backup Master Repeater:
The backup master repeater is a slave repeater. In a system, it is permitted to
configure a backup master repeater, which in normal operating conditions is the
same with other slave repeaters. Only when the master repeater fails and cannot
be connected, the backup master repeater will act to play the role of a master
repeater in lieu of the original master repeater for registration of other slave

3. System Networking Function
The repeater can be connected to BelFone intelligent interconnection system
(SDC), and supports access to the system network for repeating DMR digital
voice and data services, so as to realize interconnected communication in the
networked mode.
Note: System networking is optional.
repeaters.
Peer:
An peer is a slave repeater, in a system, it is permitted to configure multiple slave
repeaters. Upon programming software, it is required to configure slave
repeaters, the backup master repeater and the current repeater’s IP address for
successful registration with the master repeater.
Authorization Code: Peers shall have consistent authorization codes with the
master repeater for successful registration. For an authorization code, it is allowed
to enter a maximum of 16 digits and letters from 0~9 and A~F; it can be null if
nothing is entered.
DHCP: When a peer is set to DHCP, the router will act as the DHCP server and
automatically assign an IP address to the peer.
(The router shall support DHCP, and the IP address assigned shall be within the
same network segment of the master repeater’s IP).
● When the current repeater is connected as a master repeater, it is required to
configure its IP, UDP port, gateway IP, network mask, NDS server IP, UDP port;
● When the current repeater is connected as a backup master repeater, it is
required to configure its IP, UDP port, gateway IP, network mask, DNS server IP,
UDP port and master repeater IP, master repeater UDP port;
● When the current repeater is connected as an peer, it is required to configure its
IP, UDP port, gateway IP, network mask, DNS server IP, UDP port and master
repeater IP, master repeater UDP port, backup master repeater IP, backup
master repeater UDP port.
Note: In one system, only one “master repeater” and one “backup master repeater” are
permitted; other repeaters shall be configured as “peers”.
The function is optional.

Analog Mode Function
If the channel operates in the analog repeater mode, and the current channel
currently has any voice service under repeating, indicator A will flash green,
indicator B will flash red.
Smart Digital-Analog Switch
This repeater supports digital and analog channel auto switching, it can smartly
select the right one based on the type of received signal and then transmitting.
Back-to-Back Function
The repeater supports the back-to-back function to realize back-to-back
connection between a single repeater and other device for repeating voice. The
current device supports back-to-back connection of digital channels and that of
analog channels. The back-to-back function can be set via the programming
software or the preprogrammed [Back to back Switch] key.
Note: Back-to-back connection of analog channels requires the GPIO BUSY line set via
the programming software to output an active level and the PTT line to input an active
level. The “active level output by the BUSY line” of the current device shall be the same
with the “active level input by the PTT line” of the other back-to-back device.
Simulcast Function
The repeater supports Simulcast function. When the Simulcast function is
enabled, the repeater can be registered as an peer with the base station
controller of BelFone intelligent interconnection system to realize networking of
Simulcast function.
Note: Simulcast function is optional.
Positioning Service
The repeater supports satellite positioning, and can have the positioning type set
via a programming software to: GPS/BD/GPS+BD. The position switch can be set
via the programming software or the preprogrammed [Satellite Positioning Switch]
key. When GPS is enabled, the LCD will show icon: , When GPS is
disabled, the LCD will show icon:
