DTE/DCE Settings |
RS232 DB25 Connector pin outs |
Setting 1 |
RS232 data is received on pin 2
RS232 data is transmitted on pin 3
Network direction control is provided by pin 4 |
Setting 2 |
RS232 data is received on pin 3
RS232 data is transmitted on pin 2
Network direction control is provided by pin 5 |
| Power Source: |
External power supply (9VDC, 200mA) or interface powered from the RS485 network |
| Primary Power: |
The primary power LED should be illuminated solid green. 9VDC can be supplied from the RS485 connector PIN 4+, PIN 5- or through the RS232 connector PIN 9+, PIN 10-. |
| Isolated Power: |
The isolated power LED should be illuminated solid green. This lamp indicates the isolated power supply that powers the RS485 portion of the converter circuit is operational. |
| Operating conditions: |
-20 to +85°C (-4 to 185°F)
0 to 93% relative humidity |
| Network Transmit: |
This LED will be illuminated when the RS485 driver is active and driving the network. |
| Direction, Receive Data, Transmit Data: |
Under conventional quiescent conditions, all three of these lamps will be illuminated green. |
Operating voltage:
(power supply requirement) |
External power supply: 9-12VDC, 200mA (AC adapter supplied as an option)
or interface powered from the network |
| Electrical connections: |
RS232 side: DB25 male or DB25 female (specify upon ordering)
RS485 side: 2 Data, 2 power and 1 shield screw terminations (22-12 AWG wire)
External power supply: Connect 9VDC to pins 4+, 5- on the RS485 side screw terminal or the network interface power to pins 9+, 10- on the RS232 DB-25 connector |
| Dimensions: |
