Installing the Epson printer interface
Installing the Epson printer interface
1. Check advice note.
Check engineering advice note in case the system is to be installed without prior knowledge of store personnel. Only
contact the nominated manager / supervisor in such a situation.
Ensure that the store (check-out supervisor or nominated person) have taken readings from the register before it is
powered down.
2. Identify the EPSON TM-T88 printer.
The EPSON TM-T88 is a modular printer and as such has no fixed position. It is therefore important to identify both the
printer and a suitable location for mounting the printer interface.
3. Install the Interposer Cable.
WARNING! - RISK OF ELECTRIC SHOCK.
Ensure power to the printer and terminal is off and the power cord(s) disconnected before connecting the interface.
Remove the printer-to-CPU cable from the RS-232C port at the rear of the printer. Connect the interposer cable supplied
with the interface to this port. Re-connect the printer-to-CPU cable into interposer cable.
Ensure that the locking hardware is secure.
4. Installing the printer interface data cable.
The interface data cable runs from the interposer cable and should be routed along the most direct route available to the
printer interface.
5. Check printer operation.
Before supplying power to the interface connect the power cord(s) back to the printer and terminal and ensure that power
is restored. Check the printer and terminal for normal operation (It may be necessary to contact nominated store
personnel to do this).
6. Power the interface.
As the interface only passively monitors the data line and the units are opto-isolated there should be no degradation in
printer operation once the interface is powered.
If possible, check that valid text is appearing on Laptop/PC and/or Vi-POSCON screen(s).
If the printer displays abnormal operation, check that all connectors are seated properly. If this does not resolve the
problem, return the register to its initial state by removing the interface and contact your FTSS.
