HARDWARE INSTALLATION:

Die EX-47901 ist ein RS-232 zu RS-485 Konverter für PC, Workstation oder Server. Die EX-

47901 stellt einen RS-485 Half-Duplex Ausgang zur Verfügung. Die DB9-Buschs (DCE) wird

direkt auf den RS-232 Port Ihres PC‘s eingesteckt. Der benötigte Strom wird vom Standard RS-

232 Signal bezogen. Sollte aber das RS-232 Kabel zu lang sein oder es steht keine Handshake

Leitung zur Verfügung, besteht die Möglichkeit extern 12V DC an dem Terminal Block (RS-

485seitig) anzuschließen.

TERMINATOR CONFIGURATION:

ANSCHLÜSSE:

There 2 internal built-in terminators configured as the following diagram:

Since this converter supports RS-232 port-powered feature, most of the cases you don’t need

to connect any external AC power adapter on it. The internal circuits of the converter will con-

vert the power from the RS-232 signals. However, in the following cases you may need a +12V

DC power on its 5-pin Terminal Blocks.

• If the RS-232 cable is too long and unable to provide enough power

• Your RS-232 only provides 3 wires (TXD, RXD, GND) RS-232 signals, then the power of its

RS-232 port is not enough

1. Use static electricity discharge precautions.

Remove possible static discharge potential from any objects that the converter may come in

contact with before installation. This can be accomplished by touching a bare metal chassis

rail after you have turned off the power.

2. Locate an unused RS-232 port (with DB9 male connector, configured as DTE), insert the

DB9 female connector of the converter on it

3. Connect the RS-485 cable from the converter’s Terminal Block connector to the RS-485

devices. The converter only supports RS-485 2-wire half duplex operation, please connect

the wires according to the silk printing next to the Terminal Block connector pins.
