5. Back-to-Back repeater

This layout and settings may be used if you need to operate different parts of the radio network on

different frequencies. Connection between these two parts is realised by Back2Back connection between

two RipEX's (hereafter referred to as border RipEX's), each of which operates on different frequency.

Ethernet

If end devices are connected to RipEX's over Ethernet, border RipEX's can be connected with an

Ethernet cable. IP addresses of all RipEX's as well as connected devices must be within the same

LAN. Ethernet interfaces must be interconnected for proper function of remote service access.

COM

If end devices are connected to RipEX's over COM interface, one (any of the two) COM port of a border

RipEX must be connected to a COM port of the other border RipEX using RS232 crossover cable or

null modem. Communication parameters of both connected ports must be set to the same values, we

recommend using the highest available speed.

Important

Border RipEX's should be interconnected via one COM port only, connecting both COM

ports would create a loop.

Limitation: If a device is connected to the free COM port of a border RipEX, it only sends data to its

part of the radio network. Data from all other COM ports of other RipEX's throughout the entire network

will be delivered to both COM ports of all other RipEX's.

Ethernet + COM

If end devices are connect to RipEX's both over Ethernet and COM ports, or if you require remote access

to a network which uses COM ports, border RipEX's must be interconnected both via Ethernet (see

1.1) and COM (see 1.2).

5.2. Back to Back in Router mode

In Router mode border RipEX's are interconnected by Ethernet cable. Routing in both parts of the

network must be set up so that communication passes through the Ethernet interface of the border

RipEX's. We recommend splitting both radio networks to two separate LAN networks.
