Rs-232 Cabling/Pinouts - RTI XP-3 Installation And Operation Manual

XP-3
CHAPTER 3 | INSTALLATION AND OPERATION
RELAYS
The two relays in the XP-3 can provide contact closure or switching control
for loads up to 5A/30VDC each. Both relays are Normally Open when not
energized, but they can be programmed to behave Normally Closed as long
as power is applied to the XP-3.
For contact closure control, connect the A and B contact terminals of a
relay to the desired device.
ETHERNET
This RJ-45 port allows connection to a 10/100 Base-T Ethernet network
(LAN) for programming, control and two-way communication with
compatible devices. Network settings such as the IP address are
configurable within Integration Designer. This port also supports Power-
over-Ethernet (POE) which will power the XP-3 (see powering section).
USB PORT
Used to download the Integration Designer programming software or
firmware into the XP-3.
RS-232 PORT
The XP-3 is capable of two-way RS-232 communication and uses industry
standard cat5 cable with RJ-45 termination (EAI-561).
NOTE: RS-232 communication is limited to 50 feet depending on the baud
rate.
