Aprisa SR+ Product Description
Interface Specifications
Ethernet Interface
The Aprisa SR+ radio features an integrated 10Base-T/100Base-TX layer-2 Ethernet switch.
To simplify network setup, each port supports auto-negotiation and auto-sensing MDI/MDIX. Operators can
select from the following preset modes:
Auto negotiate
10Base-T half or full duplex
100Base-TX half or full duplex
The switch is IEEE 802.3-compatible. It passes VLAN tagged traffic.
General
Interface
RJ-45 x 2 (Integrated 2-port switch)
Cabling
CAT-5 UTP, supports auto MDIX (Standard Ethernet)
Maximum line length
100 metres on cat-5 or better
Bandwidth allocation
The Ethernet capacity maximum is determined by the
available radio link capacity.
Maximum transmission unit
Option setting of 1522 or 1536 octets
Address table size
1024 MAC addresses
Ethernet mode
10Base-T or 100Base-TX
Full duplex or half duplex
(Auto-negotiating and auto-sensing)
Diagnostics
Left Green LED
Off: no Ethernet signal received
On: Ethernet signal received
Right Green LED
Off: Indicates no data traffic present on the interface
Flashing: Indicates data traffic present on the interface
RS-232 Asynchronous Interface
The Aprisa SR+ radio’s ITU-T V.24 compliant RS-232 interface is configured as a Cisco® pinout DCE. The
interface terminates to a DTE using a straight-through cable or to a DCE with a crossover cable (null
modem).
The interface uses two handshaking control lines between the DTE and the DCE.
