TM 1184 Issue 1 AL1 (May 1997)Page A1 - 10
Serial Protocol a) MEP: The only serial option for MEP protocol is the Timeout setting:
Options
Setting Timeout Setting Timeout
0 100 ms 4 4 seconds
1 1 second 5 5 seconds
2 2 seconds 6 6 seconds
3 3 seconds 7 7 seconds
NOTE: The Timeout settings are designed to allow flexibility in
the response times from different external devices.
b) ESPA: There are two options: <Turn-Round / Response Time’ and <Suppress
Response Option’.
i) Turn-Round / Response Time:
Setting Turn-Round Time Response Time
0 approx 10ms 150ms
1 30 - 40 ms 300ms
2 100ms 3s
3 1s 10s
NOTE: Turn Round time is a delay introduced before
transmission allowing intervening hardware, such as
convertors or modems, to change configuration or
direction.
Missed Response time is the period after transmission
that the RPE 673 waits for an acknowledgement.
ii) Suppress Response - Valid input is <0’ (disabled) or <1’
(enabled). When enabled, the automatic responses back to
the External Device from the RPE 673 will be suppressed (not
sent).
NOTE: Suppression is beneficial if the operation of the
RPE 673 is slow.
Code Format Determines the digital data format (Mk6 or Mk7) to be sent by the Serial Encoder.
Valid input is ‘6’ or ‘7’.
System Address A single numeric digit which must match the most significant digit of the Receiver
Identification Code (RIC) for the corresponding paging receiver. Valid input is 0 - 9
for Mk6 and 0 - 3 for Mk7.
Time-of-Day If set to ‘1’ (on) then Time-of-Day paging calls will be sent at one-minute intervals
Option and, Mk7 paging calls will contain an updated time-stamp.
If set to ‘0’ (off) then Time-of-Day calls will not be sent and, Mk7 calls will contain
a fixed time-stamp.
