7.0 External Devices: Printers, PCs and Scales
The DC-788 Counting Scale is equipped with an RS-232C port that allows the scale to communicate with either
an external printer or a PC. SPC 05, Bit 3 and Bit 2-Function of RS-232C Interface must be set to 00: PC or 01:
Printer for communication to take place (For instructions on how to program Customer specifications, see
Section 3.1.1.). It also comes standard with a remote scale channel that enables you to add a second channel (See
Section 7.4 for instructions on how to program the remote scale channel.)
7.1 Printer Connection
Because the DC-788 downloads label formats to external printers in some circumstances (see Section 7.2 below)
external printers should be connected to the DC-788 and powered on before powering up the DC-788. The type
and configuration of the printer cable needed will vary by printer. Below are the pin assignments for the
connectors to the external printers that can be specified in SPC 09 - External Printer Type.
