Symbol | Color | Indicates | Explanation |
| Green | Run | Startup: On solid during initial stage of boot-up, followed by a fast blink until beginning normal operation. Slow blink: Software is in normal operational mode (one blink every 2 seconds). Fast blink: Unit is in process of being reconfigured (2 blinks/second). |
|
Amber
|
Unused | Startup: Turn on after the Run light, then go off when operating system begins to load. Otherwise, these LEDs are unused by the RediGate application. However, they may be controlled by a user application using Linux commands such as: echo 255 > /sys/class/leds/led:1/brightness #turn LED1 on echo 0 > /sys/class/leds/led:2/brightness #turn LED2 off
echo timer > /sys/class/leds/led:3/trigger #set LED3 to blink regularly on interval echo 500 > /sys/class/leds/led:3/delay_on #LED3 on-time (ms) echo 500 > /sys/class/leds/led:3/delay_off #LED3 off-time (ms)
echo none > /sys/class/leds/led:3/trigger #LED3 non-blinking |
| Red | Unused | (see "Amber" LED description above) |
| Blue | Cellular (110C and 120C only) | Startup: Turns on after LED2, then goes off when operating system begins to load. Solid: Successfully connected to cellular IP network. Solid/Fast blink: Every 3 seconds, fast blink off/on to indicate number of bars of cellular signal strength: 1 bar: -111 to -96 dBm 2 bars: -95 to -81 dBm 3 bars: -80 to -64 dBm 4 bars: -63 dBm or better Off: Not connected to cellular IP network. |
...
The RediGate provides a Micro-USB port on the front for configuration with the ACE program or for local diagnostics using a serial terminal program (such as HyperTerminal, PuTTY, or Tera Term). A USB to Micro-USB cable should be connected from a computer to the USB port on the RediGate, which is marked on the label with the icon:
| Note | ||
|---|---|---|
| ||
You must configure the Micro-USB port as COM0 in the ACE program, using port settings of 115,200 baud, no parity, 8 bits, 1 stop bit. These are the default settings for Linux startup messages. There must also be a SerialMMI object using COM0 under Servers. |
Device Serial Port
The RediGate 110E and 110C provide one DB-9 serial port for the local device communication. The port is software-configurable using the ACE program as either RS-232, RS-485, or RS-422 (in the ACE AsyncPort object, set the “Rx Buffer Size” option to ‘232’, ‘485’ for 2-wire RS-485 operation, or ‘422’ for 4-wire RS-485/422 operation). The location of the serial port is indicated on the RediGate label with the serial icon:
| Note | ||
|---|---|---|
| ||
You must configure the DB-9 (RS-232 or RS-4850 port as COM2 in the ACE program, using port settings appropriate for your application. |
WARNING: DO NOT CONNECT OR DISCONNECT CABLES WHEN ENERGIZED, UNLESS POWER HAS BEEN REMOVED FROM THE EQUIPMENT OR THE AREA IS KNOWN TO BE FREE OF IGNITABLE CONCENTRATIONS OF FLAMMABLE SUBSTANCES.

The direction of data with respect to the RediGate serial interface (COM2) is such that the RediGate acts as a DTE (Data Terminal Equipment) device. The pin-out of the DB-9 serial interface in RS-232 mode is as follows:
