RediGate 100 Hardware
The RediGate is supplied with a rugged metal housing, with hardware options that vary depending on the model and are indicated by symbols located on the product overlay. The front panel of the RediGate contains (in order from left to right):
Power input connector and status LEDs
Two Communication Ports (serial, Ethernet, and/or cellular antenna)
Micro-USB port for administrative console
The following sections describe the operation of the status LEDs and each of the hardware options and connector pinouts.
Status LEDs and Device Ports
There are four status lights that indicate the operational state and communication of the RediGate. The LEDs are located above the power input connector and are indicated with symbols on the product overlay. The normal operation of the Cellular LED is only valid for a RediGate with cellular modem and depends on a correct configuration and an active cellular account and/or SIM card associated with this RediGate.
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. Off: Not connected to cellular IP network. Solid or Off, with Fast blink: Every 3 seconds, fast blink off/on to indicate number of bars of cellular signal strength: 1 blink: -111 to -94 dBm 2 blinks: -93 to -80 dBm 3 blinks: -79 to -64 dBm 4 blinks: -63 dBm or better |
Ethernet Ports
The RediGate 110E and 120C provide one Ethernet port for network communication, and the RediGate 120E provide two Ethernet ports.
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.
Ethernet ports do not provide Power over Ethernet (PoE) and should not be connected to an unregulated PoE device.
Ethernet ports not suitable for direct connection to WAN unless an appropriate interface is provided, to ensure lightning surge protection.
Ethernet ports are 10/100 Mbps and are configured via the ACE program for either a fixed IP address or dynamically assigned DHCP addressing. The ports should be configured to operate on different, non-overlapping IP addresses/subnets. Ethernet ports are identified with the icon:
On all RediGate models, the Ethernet port located toward the right of the faceplate (on the 110E, or the rightmost port of the 120E) is identified as ‘eth0’. The port located next to the power connector (on the 120C, or the leftmost port of the 120E) is identified as ‘eth1’. This is important to note when configuring the RediGate in the ACE program, as the Instance Number of the Ethernet objects in ACE must match the numeric value of the actual Ethernet port. The identifications of the ports are shown in the pictures below.
Installing Ferrite Core
To ensure compliance with Electromagnetic Emissions Interference (EMI) standards, the user must install the ferrite on the Ethernet cable during installation (see picture).
The ferrite is supplied with all models of the RediGate with Ethernet ports. It is a 250 ohm, 100 MHz ferrite, Laird model 28A2029-0A2 or similar. | |
USB Configuration Port
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:
USB port COM0
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:
Serial port COM2
You must configure the DB-9 (RS-232 or RS-485) 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.
RS-232 Serial Interface
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:
Pin | RS-232 Name | Type | Description |
|---|---|---|---|
1 | DCD | Input | Data Carrier Detect |
2 | RXD | Input | Receive data |
3 | TXD | Output | Transmit data |
4 | DTR | Output | Data Terminal Ready |
5 | GND | Common | Ground |
6 | DSR | Input | Data Set Ready |
7 | RTS | Output | Request To Send |
8 | CTS | Input | Clear To Send |
9 | RI | Input | Ring Indicate |
When configuring the RS-232 ports using the ACE program, the Flow Control setting allows for hardware flow control (“RTS/CTS” setting), which may be required to control sending and/or receiving data through certain external devices, such as modems. If hardware flow control is not required, set the Flow Control to None (use ‘-1’ for both Warm-up Time and Warm-down Time).
RS-485/RS-422 Serial Interface
RS-485/422 uses an optically isolated, balanced differential system, in which the voltage produced by the driver appears across a pair of signal lines that transmit a single signal. A balanced line driver produces a voltage from 2 to 6 volts across its positive and negative output terminals. A balanced differential line receiver senses the voltage state of the transmission line across the two signal input lines. Up to 32 RS-485 devices or 10 RS-422 devices can be connected together in a multi-drop configuration.
The pin-out of the DB-9 serial interface (COM2) in RS-485 and RS-422 modes is identified as follows (all pins not listed are unused):
4-wire Pinout:
