ALTERNATIVE POWER SUPPLY ARRANGEMENTS
The DP-520 Wired printer is designed to be operated from a 9V to 36V voltage source that is capable of supplying
the primary power for the printer.
The electrical specification for the power supply input is:
Input Voltage Range: +9V to +36V (internal over voltage at 37V and reversal protection)
Supply Current Requirement: 100mA ( Printer in Idle Mode )
( typical @12V in ) 2A average ( Printer Printing )
7A peak ( Printer Printing )
Note: The average and peak current requirements can be adjusted by firmware control codes.
See the Programmer Guide or contact Able Systems for details.
The recommended power supply input is either a 12V or 24V vehicle battery, this allows the printer to perform at its
best. However, the printer will automatically accommodate any DC input voltage in the range 9V to 36V. In
addition, power supplies with lower current capacities may be accommodated by varying the internal PowerSave
parameter. See the Programmer’s Manual for more details.
DATA CABLE
An optional serial data cable suitable for connecting the printer to a standard PC is available. (Note: This cable
features an integrated charger connector in the housing of the DB-9 connector which is not required for this printer.
Please make no connection to this integrated connector.)
The connections to a standard PC COM port are as follows:
DB-9 Pin Name Description (refers to PC) RJ12 Pin
3 TxD Serial Data Output 3
2 RxD Serial Data Input 4
6 & 8 CTS & DSR Busy Input 5
5 SGND Signal Common 0V 6
EMC STATEMENT
The DP-520 printers are fully EMC (Electro-Magnetic Compatibility) compliant and are CE marked accordingly. A
Declaration of Conformity, in accordance with the EMC Directive 89/336/EEC (and as amended) is available on
request.
EMC Caution
System EMC compliance remains the responsibility of the system designer. It is recommended that shielded cables
are used; grounding arrangements will depend on the application.
