RJ45 Fully-Wired Terminal/Printer Cable

Using a 10-pin RJ45 plug, the cable wiring shown in
printers with either software of hardware handshaking. This cable is valid with any RJ-45 serial
port.
Most terminals and printers use Request to Send/Clear to send (RTS/CTS) for hardware
handshaking. The cable shown supports this method.
Table B-9 lists the pin-out connection between the RJ45 adapter and the DB25 terminal/printer
with RTS/CTS handshaking.
