Overview
The ESCG is intended to connect devices with ethernet or serial interfaces to a Wireless Local Area Network
(WLAN) corresponding to the 802.11 a/b/g standard. The ESCG connects over the ethernet interface all
devices in its LAN segment with a LAN that is accessible over WLAN.
The ESCG can receive and transmit data over its serial port which are exchanged over LAN or WLAN with
other devices, i.e. annother ESCG or a computer with a suitable software.
Functional blocks:
Illustration 1 Block schematic
The core of the ESCG is a 32bit network processor that controls all functions.
The interfaces:
1) Mini-PCI-Socket
2) Ethernet-Interface 10/100 MBit + auto MDI (auto crossover function)
3) 1 or 2 serial interfaces with 6 status lines each
4) optional: Relay contact and AUX input with optocouple
ESCG Manual Version 2.15

The ethernet port has a RJ45 input. Because of the auto MDI functionality the ESCG can be attached to a
HUB or the LAN port of a computer with standard patch cables. The ESCG recognizes the cable polarity and
automatically connects the right signal lines.
The serial port is a 9 pin female D-SUB connector. The pinout makes it possible to connect to a computer
COM port with a 1 to 1 serial cable, the exact pinout is shown in Illustration 1 above.
The power supply should be 8 – 30VDC / 3W. At 12VDC the input current is 250mA.

First Time Setup
To set up the ESCG it has to be connected with a patchcable to the ethernet interface of a computer.
Because of the auto MDI/MDIX capability, you can use a straight or crossover patchcable.
After applying power, the green “Link LED“ on the RJ45 connector shines when a link is detected. The yellow
“100 MBit LED“ indicates whether the connection is capable of 100 MBit.
The “LAN” LED on the front panel shines green when a connection has been established over the ethernet.
The “WLAN” LED on the front panel will be blinking red because usually no suitable WLAN is recognized.
The ESCG-Config Program
To do the „first time setup“ the ESCG has to be connected via the LAN-Interface to the computer (PC) that
runs the ESCG-Config-Program.
Illustration 3 arrangement to configure the ESCG
You have to observe:
- The connected PC should have an fixed IP address. (no DHCP)
- The LAN-Interface at the PC must be detected as connected. Check the parameter of the LANInterface with the „ipconfig“-command.
- If the LAN-Interface of the PC is correctly recognized then press the „refesh“-button of the ESCGconfig-program.
- An active firewall could prevent the communication the ESCG.
After the start the ESCG-Config-Program ascertained all network interfaces that are active at the PC. After
that the ESCG-Config-Program sends broadcast UDP requests to all these Interfaces. The registered
answers of the ESCG devices are shown in a list.
