Serial Port Connector

The Serial Port Connector is a DB-9 male connector (configured as a DTE)
supporting RS-232 serial communications including TD, RD, TRS, CTS, DTR,
DCD, DSR and GND signal lines. Use a standard serial cable if connecting to a
DCE; use a null modem (crossover) cable if connecting to a DTE.

Refer to Appendices D, and E for connection pin-outs.

Power Connector

Power is supplied to the ES1A by a 5VDC 500ma power supply. The power
connector is a 5.5mm by 2.1mm barrel jack. The tip is positive.

Connecting the Hardware

Typically, the ES1A is connected to a network via a hub, switch or router
using standard CAT-5 cable. Configuration is accomplished over the
network, or via a direct connection (see below) using the Web Configuration
and Management Interface

Configuration Connections

Your ES1A converter typically is configured over the network connection
using standard browser software. It also could be connected directly to a PC
network adapter. To do so an Ethernet crossover cable is required.
