2.8 Terminal Indicators
Teklogix terminals use LEDs (Light Emitting Diode), onscreen messages and
beepers as indicators.
2.8.1 LEDs
Transmit And Receive
Two LEDs indicate the transmit and receive status of data. On the 7035, they are
located on the left and right of the <SCAN> key. On the vehicle-mounts, the LEDs
are located to the left on the keyboard and are labelled TX and RX
• The amber TX (transmit) LED flashes when the terminal transmits data.
• The green RX (receive) LED flashes momentarily during the boot process.
After boot up, it flashes when the terminal receives data.
Key Shift LEDs – 8255 And 8260 Only
The 8255 and 8260 vehicle-mount terminals are equipped with additional LEDs that
indicate whether or not a mode key is locked “on”. Mode keys include – <CTRL>,
<ALT>, <SHIFT>, <ORANGE> and <BLUE>. For example, when the <CTRL>
key is locked “on”, the “CTRL” LED stays on solidly. If a key has been activated
but is not locked “on”, the “CTRL” LED blinks.
2.8.2 The Status Area – 7035 Only
The 7035 terminal has a status area at the bottom of the terminal screen that
indicates which modifier keys are currently active. The key or keys pressed are
displayed in lowercase letters at the bottom of the screen. For example, if you press
the <CTRL> key, it is displayed as ctrl in the status area.
The status area also indicates whether or not the function of a modifier key has been
locked “on”. Keys that have been locked “on” are displayed in the status area in
uppercase letters. Refer to “One-Shot Mode” on page 121 for details about locking
modifier keys.
“Onscreen Indicators – 7035 Only” beginning on page 29 lists all possible status
area messages.
