Figure 4-10 Replacing 10BASE5 Modules (EN611, EN621,EB621)
• When replacing a 10BASE2 module (EN631 or EN641), do not disconnect the 10BASE2
cable (3D-2V) from the T-adapter. If it is disconnected, the trunk line of the surveillance and
control network will be disconnected, causing an transmission error.
(1) Switch off the base unit. Check the LED indications to make sure that the power is
off.
Turn the T-adapter on the EN6 module counterclockwise to unlock it, then remove it.
Never disconnect the 10BASE2 cable (3D-2V) cable from the T-adapter.
If a dual Ethernet module (EN621) is used, disconnect the T-adapters for both buses
A and B.
(2) If an Ethernet module (EN641/EB641) for dual line configuration is used, disconnect
the modular connector CN1 on the module to be replaced.
(3) Loosen the M4 screws on top and bottom of the module, using a Phillips screwdriver,
and remove the module along the module guide of the base unit.
(4) Set the switches on the new EN6 in the same way as those on the removed EN6.
(No switch setting is necessary on the EB6.)
(5) After installing the new EN6 or EB6 in the base unit, connect the 10BASE2 cable to it.
For how to install new EN6 and EB6 modules, refer to [4.2 Ethernet Cable
Connection] in the preceding section on installation.
(6) It is necessary that network parameters are downloaded, when [Setting from Tool] is
used or multicast address setting is done. Download the parameters with connecting
Engineering Tool to serial communication port (Tool) of EN6 module. (Download form
Ethernet is not possible before downloading the parameters.)
Remove it after checking
that unit power is off.
Disconnect +12 V power
cable after switching
power off.
