5.5 Interface Details

5.5.1 RS-232 Serial Interface

The ZG310 printer has an industry standard RS-232 interface. The default parameters

are 9600 baud, 8 data bits, 1 stop bit and no parity. Other baud rates can be

programmed by control codes, or by using a setup utility available from the factory.

Serial data is expected in standard RS-232 format with -12V meaning mark or 1 and

+12V a logical 0, with reference to the common ground. The serial data output line,

TxD, transmits XON/XOFF and status information to the host at the same baud rate

and in the same format as the serial data input.

The hardware busy line is true (nominal -12V) when busy. Both serial output lines will

relax to approximately 0V when the ZG310 is off, and the user must allow a short period

after switching on before relying on the values of these signals.

Some host equipment uses a constant space condition (+12V) to indicate a reset

condition or wait state. Some battery powered host equipment present the same output

signal when they go to sleep. The ZG310 can be set to ignore this condition as detailed

in the Service Manual, but even then this type of host behavior may result in one or

more spurious characters being received and printed.
