GROUND Not used Not used When the DLA200 has the Ethernet option (option 9), the 15 way D type connector is replaced by a RJ45 ethernet connector. POWER CONNECTIONS The unit contains 2 redundant switch mode power supplies. The voltage input can be in the range of 100-240VAC. - Page 6 When the Ethernet option is fitted to the unit the user cannot change between RS232 or RS485, however the baudrate and address can still be changed. If the baudrate is changed the internal settings for the Moxa Ethernet board needs changing accordingly to match. Issue 1.00 DLA200 Dual Line Amplifier Units Page 6...

- Page 10 In order to use the Ethernet, the microprocessor in the Peak unit talks to the NE-4001T via its serial port, this means a baud rate must be set up for talking between the NE-4001T and microprocessor. This baud rate can be set to any desirable setting, as long as the NE-4001T board is setup similarly.
