Operator`s manual

There are two parameters and two sets of adjustments that can be made
in the function mode. In the function mode, you can perform operations
in one of the categories, and then you must exit to off-line. You can then
begin the process again to perform operations in another category.
The process for listing the parameters in these categories and making
changes to them is given in the following sections.
4.2 Interface Control—Host to Printer Interface
The LG31 printer contains an EIA RS-232-C 25-pin connector as a serial
interface to the host. The connector is located on the lower back of the
printer (see Figure 4–2). A BC22D-25 cable is supplied to connect the
host to the LG31 printer.
The RS-232-C signals and the associated pins on the interface connector
are given in Table 4–1. The DIGITAL serial protocol is XON/XOFF (for
a description of the XON/XOFF protocol, see the LG31 Printer User’s
Guide EK-LG31E-UG).
