SSI-RS232 master device
The SSI to RS232 converter is able to read data values from SSI encoder by using variable clock rates of up to 1MHz. It was especially developed to supply singleturn or multiturn SSI encoder. For this case there are three blocks of DIL switches in order to set the datalength of the encoder (up to 32bit), set the data format of the encoder (gray / binary), configure the clock rate (100kHz to 1MHz), set the timeout between two consecutive readings and set some other options.
The SSI-RS232 converter generates the clock signal for the encoder and reads back the datavalues. By setting a specific DIL switch the SSI master converts a gray code data format directly into a binary data format. The duty-cycle of the clock signal can vary from 50% down to 30%. This is useful if problems exists with high clockrates and long encoder connections. The encoder data values are internally stored and then transmitted to an end-device. This happens automatically (opt.) or after request (default). The SSI-RS232 converter is ready for implementation into a test equipment.

All signals and supply voltage are pluged via one 15pin SUB-D header. For quick connection there is optionally a SUB-D / skrew header adaptor available. The RS232 uses a RJ10 header. There is a USB Adaptor for a connection to a PC.
