Chapter 3: Hardware Configuration

3. Hardware Configuration

3.1 Serial Server Indicators, Switches, and Connectors

3.1.1 Indicators

One bi-color Link LED (Yellow = 10BASE-T, Green = 100BASE-T)

One green Ready LED (flashing = system ready)

One red Power LED

One red RX LED and one green TX LED for each serial port

3.1.2 Switches

Reset

A recessed reset switch that enables the unit to be reset. Insert a small plastic tool, press lightly and hold for three seconds. The Link and Ready lights will go out and then come back on.

Run/Console Switch

A recessed single DIP (dual inline package) switch that allows the Serial Server to be switched between Run Mode and Console Mode. When switched to the Console position, the Serial Server enters Console Mode. This allows you to configure the Serial Server from a PC running a terminal program, such as HyperTerminal®, without connecting the server to the network. To communicate with the connected serial device, the switch must be returned to the “Run” position.

DB9/Terminal Switch (1-Port Industrial Serial Server only)

Allows connection to the serial port (RS-232, 422 or 485) via the DB9 M connector or the five-terminal removable terminal block.

3.1.3 Connectors

Ethernet Connector

One standard RJ-45 receptacle that allows the Serial Server to be connected to an Ethernet hub, switch, or wallplate using a standard straight-through RJ-45 (male) Ethernet cable. To connect directly to an RJ-45 Ethernet port on a PC or laptop, a crossover Ethernet cable must be used.

Serial Port(s)

1-Port Industrial Serial Server: (1) serial port with (2) connector options: (1) (DB9 M) or (1) five-terminal removable terminal block

(DIP switch selectable)

2-Port Industrial Serial Server: (2) serial port connectors (DB9 M)

4-Port Industrial Serial Server: (4) serial port connector (DB9 M)

NOTE: Refer to Appendixes A, B, and C for connection pinouts.
