Scanner Interface
The 241X has two scanner interface options:
• Standard non-decoded scanner port. The ASIC (U501), in conjunction with PAL
(U101), handles non-decoded scanner communication. Signals include SOS, Video,
ScanEn, LasEn, and Gen-Cntl/AIM.
• Serial communications port for decoded scanners. The Vadem VG-230 UART
COM1 port interface controls serial communication to and from decoded scanners.
Signals include TX, RX, CTS, and RTS.
The tethered scanner (TETH-SCAN) signal differentiates between internal and external
scanners, and 5 volt VCC power is supplied to either type of scanner.
Lithium-Ion Battery Charger
The external charger in the communications dock provides the charger electronics for
the internal lithium-ion main battery. Electronics are provided to monitor the charge
status and notify the user of battery status. The battery is charged to 3.6 volts.
Lithium-Ion Main Battery
The terminal uses a lithium-ion battery pack. The maximum voltage on the battery pack
is between 3.8 volts and 4.2 volts. The standard usage terminal model, with the
backlight off at 21°C (70°F), will run for more than 7 hours from the 1350 mAh
Intermec battery pack (P/N 069429) and more than 14 hours from the 2700 mAh
Intermec battery pack (P/N 069428).
Backup Power Source
The backup power source can only be replaced by Intermec service technicians. The
backup power source consists of two capacitors connected in parallel. These capacitors
are recharged from the main battery or external DC charger. Specifications on the
capacitors are: 2.5V nominal voltage, 4.7F nominal capacitance. The capacitors are
charged to 2.4V with a maximum charge rate of 10 mA. The capacitors reach full
charge in about 15 minutes.
Light Emitting Diodes (LEDs)
The 241X has five status LEDs located just below the display in a single row. The
Battery LED is amber, and the other LEDs are green.
Microprocessor
The Vadem VG-230 is based on the NEC V30HL 8086 CPU core, which provides
PC/XT compatible core logic. The VG-230 uses a single bus architecture requiring only
one address and one data bus.
