LED OperationDeviceNet LEDsThe DNET1CHCONV has two LEDs that provide visual status information to the user about the product and the DeviceNet network. See Table 4 -4 and Table 4 -5 that follow below for how to interpret LED status indications. Table 4‑4 Module Status LED (labeled MS)
Table 4‑5 Network Status LED (labeled NS)
The DNET1CHCONV also has two (2) RS-232 activity LEDs: one for transmit (TX) and one for receive (RX). These LEDs are electrically tied to the serial data lines. The LEDs will flash when there are data signals active on the respective data lines and the DNET1CHCONV is powered. Serial Port ConnectorThe RS232 devices are connected to the DNET1CHCONV via a 3-wire communications cable to a DB9 male connector, or 5 wires if you use RTS/CTS hardware handshaking. See your RS232 device’s User Manual for details on the proper connections. The RX and TX designators below are referenced with respect to the DNET1CHCONV. Table 4‑6 RS232 Connector Signals
Figure 4‑3 RS232 DB9 Connector Pin-out Note: The maximum distance of a RS232 link is 50 feet (15m). Rotary SwitchesThere are (2) 10-position rotary switches for device address (MacID) and (1) 10-position rotary switch for DeviceNet baud rate. Table 4‑7 Baud Rate Switch (BAUD)
Table 4‑8 DeviceNet Address Switches
The Software Selectable option of the MacID allows a configuration tool or scanner to change the MacID of the DNET1CHCONV over the DeviceNet network. The Out-Of-box default for the software selectable option is 63. In order to use AAR (The address change component of Automatic Device Recovery) out of the box, you must change the switches to the software selectable range. If the device was powered previously at a different MacID, you may follow these steps to use AAR: Set the switches to MacID 63 Power the unit so that it completes the Self Test Sequence Remove the unit’s power after the Self Test Sequence is complete Change the switches to the Software Selectable Range. Re-Apply power. The unit will now come online as software selectable with an address of 63. This will allow the system to execute the AAR protocol. Remember that switch selectable devices can still take advantage of ADR. In order to take advantage of ADR in a switch selectable mode, follow these steps: Remove the faulty device Set the switches of the replacement device to the same settings as the switches on the old device. Connect the new device to the network and IO. The device will come online at the same MacID and baud rate as the old device. A scanner supporting ADR will then download the stored configuration to the device and resume normal operation.
