Original PSU is Epson PS-1?0 (PS-170, PS-180).
Male plug for DC socket is producted by MULTICOMP, part number PM3490002-A05, available at farnell.com for a few bucks.
Equivalent is NINIGI PC-MDP-401-3P available at TME. Connector is also known as “DIN 422”.
Looking at the female connector on the printer the square index is bottom, small pin is bottom left.
Right pin is +24V, Top Left pin is Ground, Shield is also Ground, small pin at bottom left is N.C.
6P6C (“rj11/rj25”) connector is used. Looking at the connector on the printer, with the clip at top, contacts at bottom, pin 1 is at the right and pin 6 is at the left.
Pin 1&6 are Ground.
Pin 3 comes from a big diode's katode, i suppose it's positive voltage output for drawer's coil. The guide says to use with pin 2 or 5 (unfortunately I didn't check them).
Standard Drawer Kick-Out connector pinout:
From the reference guide:
Conditions * A load must be provided across drawer kick-out connector pins 4 and 2 or across pins 4 and 5. (*1) * When the drawer open/close signal is used, a switch must be provided across drawer kick-out connector pins 3 and 6. (*2) * The solenoid used for the cash drawer must have a resistance of 24 Ω or higher. (*3) NOTES (*1) Operating the printer with incorrectly installed devices voids the warranty. (*2) Connecting devices other than the drawer open/close switch voids the warranty. (*3) Using a drawer or a drawer kick-out connector with an input current of 1 A or more may cause an overcurrent, which will cause the device to malfunction.
Using minicom a simple test has been made, Handshake disabled, 19200 baud 8N1 (as set on the dips and stated on the test print).
When the max number of characters in a line is sent over the serial port to the printer, the line is printed and a new line is set.
From the internet, not experimented:
The 'Open Drawer' code for Epson TM-T88II printers is “27,112,0,64,240”
From the internet, not experimented:
27,112,0,25,250
From official manual:
27 112 m: 0 if connected to pin 2, 1 if connected to pin 5 tON: on time (value x 2ms) tOFF: off time (value x 2ms)
