Cabling Requirements

Data cables must be fully shielded and fitted with metal or metallized connector shells.

Shielded cables and connectors are required to prevent radiation and reception of elec-

trical noise. To minimize electrical noise pickup in the cable:

• Keep data cables as short as possible.

• Do not bundle the data cables tightly with the power cords.

• Do not tie the data cables to power wire conduits.

NOTE: Print engines comply with FCC “Rules and Regulations,” Part 15, Subpart

“J,” for Class “A” equipment, using fully-shielded 6-foot data cables. Use of longer

cables or unshielded cables may increase radiated emissions above the Class “A”

limits.

NOTE: RS-422 and RS-485 applications should use shielded twisted pairs with

120 ohm controlled impedance as recommended in the Appendix of the ITA/EIA-485

specification.

Applicator Interface Connector

Refer to Table 10. An external DB-15 connector is present on the rear panel of the print

engine for communication with the applicator. An optional DB-15 to DB-9 adapter

cable (part number 49609) is available to accommodate existing DB-9 interfaces.

1 SIGNAL

GROUND

(+5V Return)

Ground JP1 IN – Ground return for Internal +5v power source and is available here for remote

opto-isolators, if required. (JP2 IN)

JP1 OUT – Ground return for External +5v power source. (JP2 OUT)

2+5V (Fused

at 750mA)

Power JP2 IN – Internal +5v power source supplies power to internal opto-isolators and is

available here for remote opto-isolators, if required. (JP1 IN)

JP2 OUT – External +5v power source must be connected here to supply power to

internal opto-isolators. (JP1 OUT)

3START

Input PULSE MODE – The label printing process begins on the HIGH to LOW transition of

this signal, if a format is ready. De-assert this signal HIGH to inhibit printing of a new

label.

LEVEL MODE – Assert LOW to enable the print engine to begin printing, if a format

is ready. The print engine will print new labels as long as the signal is asserted. When

de-asserted, the currently printing label will be completed and the print engine will stop

and wait for this input to be reasserted LOW.

4 FEED Input When the print engine is in an Idle state or has been PAUSED, assert this input LOW to

trigger repeated feeding of blank labels. De-assert HIGH to stop feeding blank labels

and register to the top of the next label.
