EN537 Smart Encoder
DB-9 Female connector pinout on rear of EN537 encoder:
These ports can be connected directly to a standard PC serial port with a 9-pin, three wire straight serial
cable. A "null modem" cable MAY NOT be used for this purpose since it will reverse the connections of pins
2 and 3. Null Modem cable may be used only when the intent is to connect two encoders together via the
serial port (see Cloning on page 17).
