Page 4: Firmware Revision History
Important notice for upgrading to firmware version v2.3: An upgrade to firmware version 2.3 is only possible if the firmware version of your DTM-3200 is v2.0 or higher. If the current firmware version is older than v2.0, please first upgrade the unit to v2.0. Changes: ... - Page 5 Writing 0.0.0.0 will result in an error-response, since it is an incorrect fixed IP address. The user should use the DHCP-enable setting instead Every message sent by the DTM-3200 on the RS-XXX port now uses uppercase ASCII characters. Users checking for lowercase characters should change this to uppercase.

Page 6: Introduction
1. Introduction 1.1 General description The DTM-3200 is a compact OEM module to convert ASI to or from a Transport Stream over IP (TS-over-IP or TSoIP). Next to the serial ASI interface, the unit supports a parallel interfac direction of the conversion (TSoIP to ASI or ASI to TSoIP) can be configured programmatic through the control interface. -

1. From a development PC using the serial RS-232 control interface. This way of controlling can be used for pre-configuring the DTM-3200, or for experimenting with the DTM-3200. 2. Using a controller on-board of the equipment that uses the DTM-3200 for I/O conversion. In this case I C is a plausible choice, but the other serial interfaces may also be used. -

DVB-ASI input, otherwise the Input Selector selects the parallel input. The TS Receive Cha synchronizes to the stream and determines the packet size (188 or 204 bytes). If the DTM-3200 is configured to generate FEC packets, the FEC Generator will create row and column FEC data. The IP Embedder embeds the TS packets in IP packets. -

B.2.1 DIP switch setting Before using the DTM-3200 it is essential to set the DIP switches on the DTM-3200 PCB into the ri position. The required settings of the DIP switches are shown in the table below. For a description the purpose of the individual DIP switches, refer to §3.4.4. - Page 38 Connect the DTM-3301 to a USB port on the PC with the USB cable included in the development k For this step, it is not strictly necessary to power the DTM-3200 board, because the DTM-3301 is b powered. After a while the USB connection to the interface board will become visible on the PC as COM port in the Device Manager, section Ports (COM&LPT).
