Step 1: Configuring the Hardware

Configure the card to meet your interfacing requirements by arranging hardware jumpers, as described in the following procedure:

CAUTION
Always wear a wrist strap and follow standard ESD prevention measures when handling the card.

A) Remove the card from the packaging and then place the card onto a static- free work area.
B) Set the jumpers on the card (detailed below) to meet the requirements of your application:

► GPI/O A (J1)

Four dedicated inputs control printer functions. Designed to interface to open-collector outputs, these inputs require no external pull-ups while blocking diodes allow the use of totem pole outputs from +4.5 VDC to + 26 VDC. Optical isolators provide galvanic isolation. Two print control interface circuit examples are given below.

For direct inputs –

Honeywell H-Class GPIO Option - direct inputs

Use the printer’s +5VDC and Ground to supply the devices interfacing to the GPI/O A inputs (as shown in the sample circuit, right).

For isolated inputs –

Honeywell H-Class GPIO Option - isolated inputs

To provide galvanic isolation for the GPI/O A inputs, remove Jumper JMP 9 then supply an external +5VDC source voltage to Pin 2, and remove Jumper JMP 8 then supply an external Ground to Pin 1 (as shown in this sample circuit, right).

Seven dedicated outputs are available for control, warning, and error functions.
These open-collector outputs have slew-limited signal-edge rise and fall times to prevent cross-talk in the cabling. Optional 10K ohm pull-up resistors, tied to a common point for use at either +5 or +24 VDC, are available via Jumper JMP 1.

Note: If external pull-ups are used (that is, without Jumper JMP1 installed), ensure that the applied external voltage does not exceed +30VDC.

The table below details the GPI/O A pin assignments, settings, and functions.

**WARNING**
Failure to properly configure the GPIO Port can result in damage to the printer and/or connected devices.

GPI/O Port A Jumper Overview

Pin

Function / Description

§ Pins 1 – 2 = +5VDC;
§ Pins 2 – 3 = +24VDC; or,
§ None = an external voltage (not to exceed +30VDC) via external pull-ups providing a 20K ohm feedback path through any two outputs.

| Programmable [1]. Signifies a RIBBON LOW DIAMETER warning condition.
10| Service Required| Evoked by occurrences listed under ‘Fault Messages.’[1] Active LOW.
11| End Of Print| Programmable [1]. Signifies the End of Print (EOP) process.
12| Media Out| Evoked during an Out of Stock condition. Active LOW.
13| Ribbon Out| Evoked during an Out of Ribbon condition. Active LOW.
14| Data Ready| Evoked when a label is waiting to print. After the Start of Print is received, printing will begin. For synchronization with the print cycle, End Of Print indicates the completion of the process. Active LOW.
15| Option Fault| Evoked during a Linear Scanner or RFID fault condition. Active LOW.
[1] Signal directions are given relative to the printer.
[2] If active with no current print job, “WAITING FOR DATA” will be displayed. Specifying a quantity of 9999 while keeping this signal ON will cause non-stop label printing, except in single label “Imaging Mode”, which will cause the printer to stop between labels. See the Operator’s Manual for details.
[3] For details see PRINTER OPTIONS / GPIO PORT in the Operator’s Manual.

► GPI/O B (J2)

Six unassigned inputs are designed to interface to open-collector outputs. These inputs require no external pull-ups while blocking diodes allow the use of totem pole outputs from +4.5 VDC to + 26 VDC. Optical isolators provide galvanic isolation. Two print control interface circuit examples are given below.

For direct inputs:

Honeywell H-Class GPIO Option - direct inputs 1

Use the printer’s +5VDC to supply the devices interfacing to the GPI/O B inputs (as shown in the sample circuit, right).

For isolated inputs:

Honeywell H-Class GPIO Option - isolated inputs 1 To provide galvanic isolation for the GPI/O B inputs, remove Jumper JMP 11 then supply an external +5VDC source voltage to Pin 1, and remove Jumper JMP 10 then supply an external Ground to Pin 6 (as shown in the sample circuit, right).

Six unassigned outputs have slew-limited signal-edge rise and fall times to prevent cross-talk in the cabling. Optional 10K ohm pull-up resistors, one for each of the output lines, can be used at either +5 or +24 VDC via Jumpers JMP 2 – 7.

Note: If external pull-ups are employed (that is, when Jumpers JMP 2 – 7 are not installed), ensure that the applied external voltage does not exceed +30VDC.

The table below details the GPI/O B pin assignments, settings, and functions.

**WARNING**

Failure to properly configure the GPIO Port can result in damage to the printer and/or connected devices.

GPI/O Port B Overview

JMP 4

► COM C (J4)
Recognized by the printer as Serial Port C, COM C functions as an auxiliary RS-232 interface or dedicated device port for the RFID and Linear Scanner options. Pin
assignments for the port are as follows:

Pin Number

|

COM C (J4)

---|---
1| +5V (@ .5 amps)
2| RX
3| TX
4| DTR
5| Ground
6| Ground
7| RTS
8| CTS
9| N/C

At default settings, the COM C port automatically selects its function. To force a selection, however, change the jumper settings as denoted in the table below:

COM C Jumper Setting Functions

Selected Function| Jumper and Setting
JMP 12| JMP 13| JMP 14| JMP 15
RS-232 Communications (default)| On| On| On| On
RFID| Off| On| On| On
Linear Scanner| On| Off| On| On

Note: Jumper settings override menu settings: If set for RS-232 (default) with the RFID and Linear Scanner menu-enabled, the printer will assign RFID to Serial Port B (backplane port J13) and the Linear Scanner to the COM C port.

► COM D (J3)

Recognized by the printer as Serial Port D, COM D is an auxiliary RS-232 interface.
Pin assignments for the port are as follows:

Pin Number

|

COM D (J3)

---|---
1| +5V (@ .5 amps)
2| RTS
3| Ground
4| TX
5| RX
6| Ground
7| CTS
8| DTR

Step 3: Interfacing

Interface the card according to your application requirements (see the drawing below for connector pin-outs, refer to Step 1 for signal details) as follows:

Honeywell H-Class GPIO Option - Interfacing

A) For GPIO functions connect a GPI/O interface cable to the GPI/O A (J1) and/or GPI/O B (J2) ports.
B) For RS232 communications connect a serial interface cable to COM C (J4) and/or COM
D (J3); for dedicated devices, connect the cabling from that device to COM C (J4).
Note: If using both the RFID and Linear Scanner, see Configuring Hardware Settings, above.
C) Connect the AC power cord to the printer and then turn the power switch ON.

Step 4: Configuring the Software Settings
Configure the printer’s menu settings for the option’s operation.
A) Using the Control Panel, enter the ADVANCED MENU (see the Operator’s Manual for menu navigation details):

If using the GPIO A (J1) port, configure the settings to meet the requirements of your system using the PRINTER OPTIONS → GPIO PORT → APPLICATOR menu selection;
If using the GPIO B (J2) port, refer to your MCL documentation;
If using the COM C (J4) port for serial communications, configure it to meet the requirements of your host system’s serial port settings using the COMMUNICATIONS → SERIAL PORT C menu selection; or, If using the COM C (J4) port for a dedicated device, enable that device using the PRINTER OPTIONS menu selection; and,
If using the COM D (J3) port for serial communications, configure the port to meet the requirements of your host system’s serial port settings using the COMMUNICATIONS → SERIAL PORT D menu selection.

B) After entering the desired settings exit the menu system and save your changes. The printer is now ready to operate using the GPIO option.
