Network Receiver Command Responses
The response to a command will be either a two-digit response code or the specific
information requested by a query command. Due to the limited processing capability of the
Receiver, the application software (ActiveTrac) manages the process as follows:
(a) buffers all outgoing commands;
(b) sends commands one at a time (minimum 100 ms delay between commands);
(c) confirms responses; and
(d) resends commands if no response is received within a specified time-out period.
The following set of response codes is output by the Network Receiver to acknowledge
receipt and processing of configuration and control commands:
00 Command completed successfully (ACK)
01 Duplicate Device ID (response for command <number>+)
02 Valid ID list full (response for command <number>+)
03 Valid ID list must contain at least one entry (response for command
<number>-)
04 Device ID not found (response for command <number>-)
05 Invalid entry (response for <number> commands when value entered is not
allowed)
06 Invalid command (response for an invalid or unknown command entry)
The following data is output in response to query and supervisory commands:
38c [Content: Device ID, Valid ID list, configuration settings/values; Format: Refer to
installation manual]
40c [Content: Device ID, firmware version; Format: Refer to installation manual]
