4 Installation
4.1 Power Supply
A clean DC power supply of 5V
± 5% 3A is required to power the A104B. The rise time of the supply
must be short enough to give a valid reset signal to the controller chip. It is recommended that the
power supply for the controller circuits is separate from the supply to the mechanism motor and solenoid
circuits, to minimise interference. In the event that the power supply is not adequate to power the
A104B, on board circuitry will hold the printer in reset and avoid any damage which may occur to the
printer mechanism.
4.2 Parallel and Serial Interface Selection
Serial and parallel data modes are selected using D7 (pin 1 on J3):
Parallel mode is selected if D7 is held low (connected to 0V) for a period of 100
s after the
printer is reset.
Serial mode is selected if D7 is held high or left unconnected (internal pull-up to +5V) for a
period of 100
s after the printer is reset.
In “classic” mode, the parallel interface is selected by having D7 low (logic “0”) at power up. In some
parallel applications the port driving this pin may be indeterminate at power up and so an alternative
parallel select is provided (jumpers S5 / S6). If either of the two serial/parallel select pins are held to
ground on start up, then parallel mode is selected. Both pins must be left high to select serial data. In
order to change from serial to parallel, or from parallel to serial, the printer must be reset. Serial data
Baud rates are selected on D5 and D6 when the printer is in serial mode.

Baud
Note that the combination for 9600 Baud was used to select 110 Baud in the A160B family of controller
boards.
In order to implement the baud rate the printer must be reset.
4.3 Jumpers
There are three jumpers on the A104B (refer to layout for position). Closing these jumpers will select the
following:
S1 / S2
Self test
S3 / S4
Inverted printing
S5 / S6
Alternative parallel (Classic/New Mode) select.
4.4 EMC Compliance
As a component, the A104B is outside the scope of the EMC Directive and the user must take
responsibility for the compliance of the complete equipment or installation. Please refer to the EMC
disclaimer in the Appendix.
5 Operation and Programming
5.1 Mechanism selection
All the four-needle EPSON mini-printer mechanisms (M150, M160, M163, M164 and M170) are now
supported by a single A104B device. The A104B exercises the mechanism on the first power-up, and its
type is sensed by counting tacho pulses per head cycle. The result is stored in the EEPROM, and on
