Functions and operation instructions
Digital Mode
1. Digital Repeater Mode
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.
Network Setting
Connection Type
Connection type Function

12
None IP interconnection function is disabled
Peer Set to slave (registration of the master repeater
required)
Master Station Set to master (waiting for slave repeater registration)
Master Repeater
Backup
A type of slave repeater that will automatically become a
master repeater when the master repeater fails.
Master Station:
In 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 repeaters.
Peer:
The 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.

13
Authorization Code: Peers should 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 one IP address to the peer.
(The router shall support DHCP, and the IP address assigned should 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.
3. System Networking Function

14
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.
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.
The back-to-back function can be set via the programming software or the
preprogrammed [Back to back Switch] key.

15
Simulcast Function
The repeater supports Simulcast function. When the Simulcast function is
enabled, the repeater can be registered as a peer with the base station
controller of BelFone intelligent interconnection system to realize Simulcast
networking.
Note: Simulcast function is optional.
