4 Interface Specifications

4.1 Serial Interface

The interface connector is located on the rear of the SP-401 printers.

Connector P1 is the serial port. Pin assignments are shown below. See Appendix
B for details.

Note: A valid baud rate must be set at all times for proper printer operation.

See section 4.1.1 for switch settings.

The SP-401 has two types of serial interfaces, RS-232 and 20 mA current

loop RS-485 & 20mA current loop. In general, the RS-232 interface is preferable if
the printer is located close to the host computer and can be connected with a
cable run of 50 feet or less.
