Appendix 6: External system connections
If the hub’s external system interface is to be used, a link is connected to the serial
port. The data rate should be set to the link speed (options are 300, 600, 1200,
2400, 4800 and 9600 bits per second). The data format and flow control should be
set to match that of the receiving device (options are 7 bit even parity or 8 bit no
parity with 1 or 2 stop bits). Messages will be truncated to 138 characters for TAP
messages and 128 characters for ESPA messages.
Only a single selection from those below can be made on the hub; bidirectional
paging operation has limited support by using Port A for Output and Port B as an
Input.
Options are: port A
 ESPA input (maximum 138 characters). Note that 128 characters are defined by
the standard
 ESPA output (maximum 101 characters, because only alarms are sent via this
interface). Note that 128 characters are defined by the standard
 TAP input (maximum 138 characters)
 TAP output (maximum 101 characters, because only alarms are sent via this
interface)
Options are: Port B
 ESPA input (maximum 138 characters). Note that 128 characters are defined by
the standard
 TAP input (maximum 138 characters)
Incoming pager messages are addressed as follows:
0 = all pagers
1-32 = pager group
HHHNNNNNNN for individual pagers where HHH = hardware type and NNNNNNN =
serial number.
Note: ESPA and TAP protocols do not have standardised third party implementations
– a test with third party equipment is necessary.
