Hardware Overview
All connectors, LEDs and buttons are on the front of the ESP-4 MI serial hub.
The lower left corner of the front panel contains the electrical connector. For more information, see
Electrical on page 8.
The Ethernet port supports 10/100 auto detect (speed and duplex) connections. The LAN connector
accepts 10BaseT or 100BaseT LAN interface cable. A CAT 5 cable is required for 100BaseT
operation. Table 2.6 on page 7 lists the pin assignments. See Network interface on page 4 for
information about configuring the network interface.
The PORT 1, 2, 3 and 4 connectors are standard DB-9 DTE ports in RS-232 mode. Table 2.2 on
page 5 lists the pin assignments for each interface. The unit ships with RS-422 mode enabled for
all ports.
Table 2.1 describes the LEDs and buttons on the front panel.
