* Arrows indicate which direction the signal is flowing

NOTES:

●

Altpin should be turned on when using this cable so that DTR will drive DCD (standard usage).

●

If altpin is turned off, the hardware signal on RJ45 pin 1 becomes DSR instead of DCD. This

alternative can be used if DCD is not required, and DSR is needed instead.

●

This cable utilizes the DTR signal of the terminal/printer for hardware flow control (RTS/CTS).

●

Okidata printers may use SSD (pin 11) instead of DTR (pin 20) on DB25 side of above diagram. If

this is the case, the printer should be set to SSD+.
