2.1 About the LA310 MultiPrinter Control Panel
Port Indicators
There are two port indicators:
1. Serial indicator
The Serial indicator lights up when the serial port is active or selected.
It may be active automatically because data is flowing through the serial
port, or the serial port may have been selected in Set-up Mode.
2. Parallel indicator
The Parallel indicator lights up when the parallel port is active or selected.
It may be active automatically because data is flowing through the parallel
port, or the parallel port may have been selected in Set-up Mode.
The Serial and Parallel indicators blink when the communication port is
automatic (the default setting), and when they are not currently receiving or
processing data.
Protocol Indicators
There are three protocol indicators:
1. DEC
The DEC indicator is on when the DEC PPL2 protocol is selected or active.
2. PP III
The PP III indicator is on when the IBM Proprinter III protocol is selected
or active.
3. FX/Option
The behavior of the indicator depends on the type of emulation:
• When the resident Epson FX-1050 emulation is enabled, the FX/Option
indicator is on when the Epson FX-1050 is selected or active.
• When the optional emulation through a cartridge is enabled, the
FX/Option indicator is on when the optional emulation is selected or
active.
When the protocol is driven by the active port, provided no communications
port is active at that time, the protocol indicators blink in phase with the port
indicators, to reflect which protocol is assigned to which port. For example, the
default setting is:
1. Serial indicator blinks in phase with the DEC indicator.
2. Parallel indicator blinks in phase with the IBM indicator.
NOTE: This is the default setting and can be reconfigured to suit your needs.
