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.
