Expansion Module - Motorola V186 - Cell Phone - GSM System Planner Manual

Expansion Module

The expansion module provides an interface from the CPU module (either directly or via
the expansion LAN switch) on the ACE3600 main frame to the I/O modules on the
expansion frame. This enables the CPU on the main frame to control the I/O modules on
the expansion frame and process the gathered data.
This module is installed in the I/O expansion frame in the CPU slot,
second slot from the left and is connected via dedicated LAN to the
RTU's main frame.
The expansion module includes two on board communication ports:
Exp Eth1 (E1) - 10/100BaseT Ethernet port, used to connect to
the expansion Ethernet switch or to the main CPU
STS 1 (STS1) – RS232 port, used to connect a PC running the
ACE3600 STS to perform diagnostics and other STS operations
(for distributed I/O), as if it is connected directly to the main
CPU.
The expansion module includes a (rotary) selector switch which
enables the user to determine the frame number in the expanded RTU.
The frame number is used during communication with the main CPU,
with the STS, etc. The expansion frame number range is 1 to 13. On
the selector switch, A, B, C and D refer to 10,11,12 and13.
hanging the selector position when the expansion frame is running, takes effect
Note: C
only after the next restart.
The expansion module shipped from the factory is set by default to 1. In a multi-
expansion frame configuration, the settings of additional I/O expansion frames must be
changed accordingly to provide each frame with a unique number.
The expansion module can be connected to the main frame in two ways:
Single expansion frame - Direct connection:
In a system with a single expansion frame, connect the Eth1 port on the expansion
module directly to the Eth1 port on the main CPU, using a crossed LAN cable
(V665/FKN8525A).
Switch connection:
In an RTU with more than one expansion frame, the Eth1 port on the expansion
module is connected to one of the Ethernet ports Eth2-Eth8 on the expansion
Ethernet switch (situated on the main frame). Note: The Eth1 port in the expansion
Ethernet switch is reserved for connection to the main CPU.
If two switches are used, the Eth1 port on the expansion module is connected to one
of the Ethernet ports (Eth3-Eth8) on the first expansion Ethernet switch or to one of
