1 INTRODUCTION
This document describes the basic hardware components of the Remote Maintenance
Gateway RMG/941(L,N .
1.1 Safety Guidelines
Please read the following safety guidelines carefully! In case of property or personal
damage by not paying attention to this manual and/or by incorrect handling, we do not
assume liability. In such cases any warranty claim expires.
• The power supply should be in immediate proximity to the device.
• The power supply must provide a stable output voltage at 11..28 VDC ±10%. The
output power should be at least 10 W.
• Please pay attention that the power cord or other cables are not squeezed or dam-
aged in any way when you set up the device.
• Do NOT turn on the power supply while connecting any cables, especially the pow-
er cables. This could cause damaged device components! First connect the cables
and THEN turn the power supply on.
• The installation of the device should be done only by qualified personnel.
• Discharge yourself electrostatic before you work with the device, e.g. by touching a
heater of metal, to avoid damages.
• Stay grounded while working with the device to avoid damage through electrostat-
ic discharge.
• The case of the device should be opened only by qualified personnel.

Table 8: Pinout service port
= Cable bridge
To create a serial connection between the RMG/941 and a PC an adapter cable and a null
modem cable are necessary.
The adapter cable is connected with the PC via the null modem cable like shown in fig. 2.
Table 9 shows which service port pins must be connected with the pins of a Sub-D male
connector (DTE, data terminal equipment to build an adapter cable.

4 SIM CARD
The internal SIM card of the RMG/941L and RMG/941N can be changed through the slot on
the backside.
To remove the SIM card just push it gently with a screw driver until you hear a soft "click".
The SIM card is ejected a few millimeters and can be pulled out easily.
Figure 3: Removing the SIM card
To insert the SIM card just push it by hand as deep as possible into the slot.
Please note:
Pay attention to the correct orientation of the SIM card like shown in fig. 4!
Then use a screw driver to push it gently further into the slot until you here a soft "click".
