internal radio, a separate flash EPROM holds the
program that controls the radio.
The documentation provided with
the Telxon Pen-based 11x4 Series
Software Development Kit contains
details on reprogramming flash
EPROMs.
All of the flash EPROMs can be erased and
reprogrammed while they are inside the PTC. First,
the PTC must be connected to a host computer via
cable. (See
for cable part numbers.) Then,
using the FLASHPC.EXE utility program on the host
and the FLASH386.EXE utility program on the PTC,
any or all of the flash EPROMs can be reprogrammed.
Mounting bracket
The mounting bracket, which is secured to the PTC
by mounting handles, is used to attach the unit to the
frame or housing of a warehouse vehicle such as a
forklift.
Non-vehicle mounting holes
For freezer units, make sure you
leave enough clearance to replace
the desiccant cartridge when
necessary.
Four M6x1 metric threaded holes on the back of the
PTC allow the unit to be mounted to a wall or a
horizontal surface (instead of to a warehouse vehicle).
See
for mounting instructions.
Processor
The PTC’s 50-MHz 486SLC microprocessor is fully
IBM PC compatible and provides exceptional
processing speed.
Radio
The PTC-870IM can be equipped with a single ARDIS
radio, spread spectrum radio, or MicroRadio or with
two radios in the following combinations: a 2.4-GHz
spread spectrum radio and an ARDIS radio or a
900-MHz or 2.4-GHz spread spectrum radio and a
MicroRadio. A description of each radio follows.
