5.2 Parallel Data Mode
D7 to D0 are the data connections for parallel mode 8 bit data. If using one of the backwards
compatible 7 bit character sets (A160C family) D6 to D0 are the data connections. Positive true ASCII
codes are accepted at TTL or 5V CMOS levels. The data inputs are not latched and must be static
during the handshake sequence. The Data Strobe input times the incoming data transfer. When the
printer is not busy (the busy signal is low) the data must be held static on the data pins and the strobe
signal taken low until the busy signal goes high to acknowledge the data transfer. The data strobe must
then be taken high ready to transmit the next byte. Figure 5.1 shows typical connections to a PC
parallel port.

5.3 Serial Data Mode
The serial data input accepts a TTL or 5V CMOS positive true signal. The busy signal will be low when
the printer is ready to accept data. The A104B is not suitable for direct connection to a PC RS232
COM: port. (Please refer to ASL for a converter board, or alternatively Able Systems produce an Ap25S
which is the serial RS232 version of the Ap25 and is suitable for direct connection to a PC.) Figure 5.2
shows typical connections to a PC serial COM: port for the Ap25.
