2 Making the Hardware Connections

The following information is provided to give the user an understanding of how to

connect the ESP901 to the LAN and serial device. A review of the switch settings and

the functionality of the LED’s are also provided.

Serial Connection

The ESP901 has a DB-9 male connector. The serial port is configured as a DTE (data

terminal equipment) device. All PC COM ports are DTE ports. A null modem cable is

required to make a connection between the COM port on a PC and the ESP901 serial

port. A straight through cable is required to connect the ESP901 serial port to a DCE

device.

Power Connection

The ESP901 is shipped with a 12 VDC 500mA power supply. The tip of the connector

is positive. When inserted into the jack the red power light will illuminate confirming

power has been supplied to the unit.

Ethernet Connection

A straight-through Ethernet cable can be used to connect the serial server to an

Ethernet hub, switch, or wall plate. A crossover Ethernet cable can be used to make a

connection directly to the NIC (Network Interface Card) on a PC or laptop.

Reset Button

The reset button can be found between the switch and power jack. To reset the unit

manually apply power, insert a small plastic tool, and press lightly depressing switch.

Hold for 3 seconds and release. The Link and Ready light will go out and turn back

on.
