336 Module - eESPA
Figure 81
eESPA Connection tab showing a valid configuration
Because the eESPA is designed to handle serial data communications
with a number of paging systems, the eESPA must be configured before
use. These values are returned through the <cfgrpy> reply that is sent on
return of the <cfgrqs> request.
Note: The values shown in Figure 81 "eESPA Connection tab
showing a valid configuration" (page 336) are retrieved from the DECT
Messenger database; from the KERNEL_INPGM table, and from the
eESPA, eESPA_OUTBOUND_CFG, and the eKERNEL_SITE tables.
At start up, the eESPA.exe appears the specified COM port with the
specified settings.
Note: The COM port you identify must be available, and you must
specify a valid baud rate, and so on.
As well, a physical connection between the specified COM port and the
external paging system must be available, which requires a serial cable.
In most cases, you can use a standard null-modem cable. However, in
some cases, alarm systems support a limited number of control signals
(for example, ground, send and receive), so consult the alarm system
vendor for cable specifications.
