RS-232 And RS-422 Serial Interfaces
NOTE: The RS-232 and RS-422 serial interface circuit characteristics
The RS-232 and RS-422 serial interfaces enable the printer to operate
with bit serial devices that are compatible with an RS-232 controller.
The input serial data transfer rate (in baud) is selectable from the
printer's control panel. Baud rates of 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, and 115200 baud rates are available.
NOTE: If you select a baud rate that is greater than 19200, you may
The length of the data cable from the host computer to the printer must
not exceed 50 feet (15 meters) for RS-232 or 4000 feet (1220 meters)
for RS-422. (A copper conductor, twisted-pair telephone cable with a
shunt capacitance of 16 pF/foot [52.5 pF/meter] terminated in a 100
ohm resistive load must be used for the RS-422.)
