LEDs Description
Signals the on status and correct communication with Ekip Touch:
• off: module off
• on steady or flashing synchronized with the Power led of Ekip Touch: module on and
Power
communication with Trip unit present.
• flashing not synchronized with the Power led of Ekip Touch (2 fast flashes per second):
module on and communication with Trip unit absent.
Indicates the status of the communication between network master and module (slave):
Rx • off: communication between master and module not activated
• on steady: communication between master and module activated
Indicates the status of the communication between network master and module (slave):
Tx • off: communication between master and module not activated
• on flashing: communication between master and module activated

Configurations Resistors can be connected to the RS-485 bus by configuring the dip-switches at the side of the module:

ON

1 2 3 4

Figure 126

Resistor Dip Description Default
220 Ω termination resistor
Rterm 1 and 2 Off
Move dip-switches 1 and 2 to the ON position to connect Rterm
390 Ω pull-up or pull-down resistor
Rpol 3 and 4 Off
Move dip-switches 3 and 4 to the ON position to connect Rpol

IMPORTANT: move the dip-switches before connecting the module to Ekip Supply
and the communication network

Menu Local bus activation, which is essential for starting the communication between module and Ekip Touch, is
available in the Settings menu (page 46).
Two areas are activated if Ekip Touch detects the module correctly:
• information area in the About - Modules menu, containing the software version and serial number of the
module
• specific configuration area in the Settings - Modules menu, where the following communication parameters
can be configured:
Parameter Description Default
Module address; 1 to 126 range available
Serial address IMPORTANT: devices connected to the same network must 125 / 124 (1)
have different addresses

(1) 125 default of the Ekip Com Profibus DP module; 124 default of the Ekip Com Profibus DP
Redundant module

Remote information Certain additional information concerning the version and status of the module is available via the service
connector (via Ekip Connect) or by communication via system bus; the information includes: HW and Boot
version, CRC status (correctness of the SW in the module).
