Display
This is a custom display module. The display is a full graphics type, with a matrix of
160 pixels horizontally by 128 pixels vertically, allowing 16 lines of 20 characters per

driver IC, DC/DC bias power supply, EL backlight, and EL DC/AC power supply are
provided on the LCD module.
Keyboard
The keyboard scanning electronics provide for an 8x12 matrix of up to 64 regular keys.
The number of keys implemented depends on the keyboard layout and configuration.
The elastomeric keypad provides the operator indication of key travel and tactical
feedback. Pushing a key activates the membrane keypad matrix. The membrane keypad
switch resistance must be less than 300 ohms for a valid key press and greater than 10 k
ohms for a valid open.
PC Card/Radio
The terminals use a PC card interface for additional user memory. User memory
extension is available with Intermec-supplied SRAM PCMCIA cards.
The 2415 can also use the PC card as a radio interface. The radio is connected to the
main circuit board through the PCMCIA connector. There are two types of radios:
• Proxim RangeLAN2, 2.4 GHz frequency hopping, spread spectrum radio with a 1.6
Mbps data rate
• IEEE 802.11b Direct Sequence, Spread Spectrum radio with an 11Mbps data rate,
which is Wi-Fi compliant.
