Quick Start Guide - Ultra JR50 Ethernet Data Radio
3
Communication Ports
LAN 1 and LAN 2 Ethernet Ports
The LAN 1 and LAN 2 ports are 10/100 Base-T compliant ports using an RJ-45 connector. These
ports support both TIA/EIA-568-A & B wiring as they have Auto MDI/MIDX Auto Sensing. This
means you can use both straight-through and cross-over type CAT-5 or better patch cables.
If termination of a cable is
required, then the following wiring
arrangement should be followed
(Compliant with TIA/EIA-568-A).
Note: Maximum differential voltage :
5v, 50mA max through each
differential pair.
Note: If 100-BaseT connection speed
is required, CAT-6 Shielded cable
should be used for installation to
comply with ETSI EMC directives.
Serial Port A & B Ports
The J Series Radio features a 9 pin miniature D-Shell (DE-9)
Female connector that supports two individual serial port
connections. Each serial port is associated with an embedded
serial terminal server that provides the RS-232 to TCP/UDP IP
connectivity. Refer to the user manual for more information on the serial terminal servers.
Data Port A uses pins 2, 3, 7 & 8 with pin 5 as the common ground.
Data Port B uses pins 4 & 6 with pin 5 as the common ground.
An RSSI output is available on pin 9 which is useful for antenna alignment. See below for details.
Notes:
(1) Pin 2, 6 & 8 are outputs rated at +/- 6v,
65mA max.
(2) Pin 3, 4 & 7 are inputs rated at +/- 15v,
5mA max.
(3) Pin 9 is a multipurpose IO pin with 120mA
max input / 5mA max output.
(4) Connecting wires should be #26 AWG or
larger.
