Pin-out for RS232 on Epson U220B

Need help ASAP! Various sources on the net have yielded incorrect info....

I have a generic "kit" to connect a male RJ45 to an RS232 25-pin connection, and want to connect the adapter to the back of an Epson TM-U220B receipt printer (succession to the 200 series). The printer will be on a network to serve as a kitchen receipt printer for a POS system.

I only have ONE left and have run out of time. Can anyone tell me if the following is correct? If it's not, please supply me with the correct pinout:

DB25-RJ45 end-color DB25 Pin

2 OR 8
6 YL 20
5 GRN 6
3 BLK 7
4 RD 2
1 BLU 3
7 BRN 4
8 WH 5

I would also like to know how to access the built-in web page stored on the printer. Thanks!

another prob you need to consider is if port on u220 requires nul modem. tm printers have various options for port types (see

The U375's I have are configured for straight thru

Here is how I connect a serial TM-U200:

PC = straight DB9 (DE9 actually)
3 Rd TD
2 Gr RD
7 Or RTS
8 Br CTS
5 Bk GND
1 Yl DCD
4 Bu DTR
6 Wh DSR

Printer = special DB25
2 Gr
3 Rd
7 Bl
20 Yl,Wh,Br

The TM-U200 will print with a regular null modem cable but hardware handshaking will not work. Tying DCD, DSR and CTS to pin 20 fixes the handshake problem.

I would assume that to connect to a "web page" you would need the optional 10BaseT module installed.

Thanks to everyone for the RJ45 pinout help.
