3-1
The modem unit of the
ioLink 4
contains all the software and interfaces you will need. The unit has
several connectors on the rear panel as well as LEDs, an LCD display, and a keypad on the front panel.
This section describes the function of the connections, indicators, and features in the modem unit.
3.1 Front Panel Interactions
The LEDs, LCD, and keypad are on the modem unit’s front panel. All system events and errors that occur
are indicated on the LCD or the LEDs. Because the
ioLink 4
is SNMP-compliant, you can remotely
monitor and control the device via a serial DE-9 connection to troubleshoot and diagnose problems and to
measure network reliability for quality control.
