REPLACING AN ETX 2000 PRINTER WITH AN ITX 2000 PRINTER
The ITX 2000 printers can easily drop in and take the place of ETX 2000 printers in the field. The ITX 2000 printer is a
newer more advanced printer. It brings with it higher print speeds, smaller packaging, improved interfaces as well as all of the
legacy ETX features to permit it to replace ETX’s that have been deployed, while bringing advanced features required by the
changing marketplace.
This document breaks down the areas, which need to be understood in order to make the transition, from one product to
the other.
18.1
Interface:
18.1.1
Selection:
ETX:
The ETX has a 25 pin interface connector mounted to the printer’s rear chassis. An internal ribbon cable is
attached to this external connector. The other end of the ribbon cable plugs into a Parallel or Serial interface
connector on the printer controller PCB. The selection of interface is made by: -1- the placement of this internal
ribbon cable and -2- the selection of DIP-switches mounted on the printer controller PCB. The interface being
used can be easily determined by printing the system status report (power on holding in the F0 switch). To
change interface from Serial to Parallel or, vise versa, the printer chassis is opened, the DIP switches selections
are made and the ribbon cable is moved to target interface connector on the printer controller PCB.
ITX
:
The ITX has plug-in interface modules. The interface module is plugged in from outside of the printer chassis. At
power up, it is automatically recognized by the printer controller. If it is a Parallel or USB interface nothing else
needs to be done. If it is a Serial Interface the DIP switches, on the modular interface PCB, need to be set to the
correct serial communications settings.
18.1.2
Cables:
Parallel:
ETX:
The ETX uses a 25 pin to 25 pin Parallel cable.
ITX:
The ITX uses a standard 36 pin to 25 pin IEEE1284 A/B cable.
Serial:
ETX:
The ETX could have several different cable configurations depending on the interface flow
control method and if it is connected to a PC that has a 25 or 9 pin Serial port.
ITX:
The ITX typically connects to a standard (newer) PC’s 9 pin Serial port with a straight through
wired 9 pin-to-9 pin serial cable
.
USB:
ETX:
The ETX does not have a USB interface option.
ITX:
The ITX uses a standard 4 pin USB 2.0 A/B cable.
18.2
Power Supply:
ETX
:
The ETX has a self-contained power supply. The selection for 230/115 VAC operation is made with a jumper
internal to the power supply chassis. Additionally, the line fuse is changed to match the input current based on the
operating voltage. The A.C. power connector is a IEC 320 receptacle.
ITX:
The ITX has a small external power supply module with a universal input voltage range. Voltage selection is
automatic. It has an IEC 320 receptacle to connect a power cord. Keeping the power supply external reduces the
size of the ITX printer chassis, compared to the ETX. The power supply module is small and completely self-
contained and can be mounted to any flat surface using an optional mounting bracket. With its attached 4-foot
output cable, it can easily be located in the target application somewhere along the input line cord’s path.
