Note
Prior to connecting cables, provide strain relief for them to prevent damage to the controller.

Ethernet
Two, female 10/100-Mbit Ethernet connections are provided on the JO-PC1. These are RJ-45 connectors labeled
LAN2 and LAN1. Use a standard Ethernet patch cable for connecting to a hub or Ethernet switch. An activity
LED for each Ethernet port is visible, and are labeled “LAN2” and “LAN1” on the cover.
The factory-default IP address for
LAN1
on a JO-PC1 is
192.168.1.12n
, where the last numeral
n
in the
address matches the JO-PC1’s serial number, and subnet mask is
255.255.255.0
. By default, LAN2 on a
JO-PC1 is disabled. Refer to the
JENE NiagaraAX Install and Startup Guide
for details on changing IP address.
Note
Typically, you
only use LAN1
(primary port), unless you have a specific application for isolating a
driver’s network traffic to a separate LAN, using LAN2. Do
not
use LAN2 as the primary port.
Serial
There are two serial ports on the JO-PC1 base unit. Each has a UART capable of operation up to 115,200 baud.
At the bottom of the board (see
), the left port is an
port using a DB-9 plug (male) connector.
To the right of this is a two-wire with shield
port, using a screw-terminal connector plug.
Note
A green “receive” LED and yellow “transmit” LED are provided for each serial port. These LEDs are
located on the bottom board, on the
opposite side
of the serial connectors (see
These LEDs are labeled on the board (COM1, COM2) and are not visible with the cover on.
RS-232—
An RS-232 serial port using a male DB-9 connector always operates as COM1. You can use standard
DB-9 serial cables with this port. The JO-PC1 is a serial DTE device, such another DTE device (PC, for
example) requires a “null modem” cable. If connecting the JO-PC1 to a DCE device (modem, for example), a
straight-through cable is used.
