V.24 - RS232 connections (eCAP, eESPA) 155
eCAP
There are four different types of devices that can be connected to the
eCAP module using V.24/RS232, as follows:
• Nurse Call systems
There are many types of Nurse Call systems offering data using
V.24/RS232. However, there is no standard protocol.
• Building Management systems
There are many types of Building Management systems offering data
using V.24/RS232. However, there is no standard protocol.
• Paging systems
There are many types of Paging systems. Almost all offer a
V.24/RS232 interface carrying the ESPA protocol. If the paging System
supports ESPA 444 protocol, use the eESPA module instead of the
eCAP.
•
Line Printer Protocols
Some older Building Management systems offer a line printer
protocol over V.24/RS232. This is a simple type of protocol, offering
only incoming data. There is no guarding on the protocol, such as
ACK/NAK, or timers.
Before using the eCAP module, check which protocol is offered, and check
with Nortel, to see if the protocol is supported by DECT Messenger.
If the protocol is supported, install the correct eCAP module. If a Line
Printer protocol is required, you can build the protocol yourself.
Remember that the DECT Messenger structure is based on five
parameters; see “Parameters required to set an alarm” (page 106). You
must know which parameters are coming in from the external system,
and you must specify these parameters in DECT Messenger. For
more information, see the chapter Module - eCAP in
DECT Messenger
Installation and Commissioning (NN43120-301), which describes the
supported protocols in detail.
eESPA
The eESPA module supports the ESPA 444 protocol. This is a complex
protocol; see the chapter Module - eESPA in DECT Messenger Installation
and Commissioning (NN43120-301) for more detailed information about
the protocol. Read the information provided for the protocol before
attempting to set up the eESPA Module.
