GUIDE TO INSTALLATION AND OPERATION
LGK-3901/DSK-3901 | 47
5.4.7 ETH
ETH is an RJ45 Ethernet 10/100BaseT port which automatically negotiates the fastest speed possible for
downloading media (LGK-3901 only) and configuration files (LGK-3901/DSK-3901).
The pin-out of the ETH port is:
Pin No Signal Name RJ45
1 TDP
2 TDN
3 RDP
4 NC
5 NC
6 RDN
7 NC
8 NC
5.4.8 COM 1
COM 1 is an RJ45 port that provides serial bidirectional communications to external Automation systems, EAS units
(LGK-3901 only with LGK-3901-OPT-EAS) or a slave Intuition XG device. The serial port type can be configured as
RS232 or RS422, and the baud rate set to 1200, 9600, 19200, 38400, 57600 or 115200. The serial port can also be
set to receive Oxtel Automation commands or to transmit certain Oxtel Automation commands to a slave Intuition XG
device. For EAS the serial port will receive ENDEC 1822 and TFT EAS 911T protocols, and for the Temperature
Probe it will received ST61XX TEMP SENS protocol.
5.4.9 COM 2
COM 2 is an RJ45 port that provides identical functionality to COM 1. This allows two external devices (for example,
Automation and EAS) to independently control the LGK-3901/DSK-3901.
The pin-out of the COM 1 and COM 2 ports is:
Pin No Signal Name RS422 Signal Name RS232
1 TX+ RTS
2 TX- TXD
3 RX+ CTS
4 NC NC
5 NC NC
6 RX- RXD
7 NC NC
8 GND GND
