CHAPTER 8: SPECIFICATIONS
iec61162-2

coMMunicaTion
This standard requires a common signal ground between system requiring extra circuitry for isolation
on the receiver side. This unit does not have this circuitry, and cannot fullfill the receiver part of
the standard, however by connecting the common signal ground to pin 10 marked Common, the
transmitting part of the standard is fullfilled.
iec61162-450
eTherneT
coMMunicaTion
The system is defined as ONF2 and SF,NF as per the standard (§4.1). This means it will send and
receive encapsulated messages as defined in these standards, but has in addition web pages with
a seperate IP address. The -450 standard requires the UdP multicast messages to have a unique
identifier, and transmission group. See “” on page 39
The system can be connected to a standard network using CAT 5 or better cables, the system will
load the network with a maximum datarate of 20Kb/s (typical 3Kb/s). and will operate a network loads
of up to 20 Mb/s or 10000 datagrams per second. The maximum number of datagrams directed to
the unit must not exceed 2500/second (normal usage is 3-5).
Error codes are logged if the formats are not accoring to specification. These messages can be
retrieved and viewed using the “Upgrading and external diagnostics of the system” on page 35.
The CD401CU must be paired to the JB70D1 unit, this to make sure the CD401CU talks only to one
electronic unit on the network. To do this the user must enter the SFI ID of the JB70 unit into the
web page of the CD401CU. For example VD0133, if the unit is only to have 1 control unit, then the
control unit SFI ID can be entered into the JB70 unit. if no SFI is entered into the JB70D1, then any
CD401CU with the correct destination SFI will work, allowing multiple control units.
