RUBIDIUM VL Module:
Features
|
LTCdecoder for MTD
Four built-in amplifiers
Distribution amplifier for serial telegrams
Four RS232 and RS422 interfaces
|
The VL module is an LTC distribution amplifier and converter with two LTC inputs and four LTC outputs,
four RS232 and RS422 outputs, and four output stages for impulse telegrams.
|
All outputs have their own drivers and are individually configurable. Each output signal is phase locked
and synchronised to the LTC reference input. LTC time and user data are decoded. MTD timers can be converted into independent
LTC signals, or various serial protocols. Impulse time signal outputs are also available for the accurate control of analog
clocks.
|
| LEDs located on the front of the module indicate the operating status. Built-in GPI's can be pre-programmed
to signal errors or other pre-programmed warnings.
|
| The standard functions of the module are:
|
Reading and decoding LTC
Generating LTC: as „Refresh“of the read LTC, or as read LTC time + Offset, or as decoded MTD time.
Sending RS232 and RS422 time and date information
|
Two different time offsets (± HH:MM:SS:FF) can be programmed. These can be added and/or subtracted from the time information
of the read LTCs (LTC_REF and LTC_VTR):
|
LTC_REF ± Offset1, LTC_REF ±Offset2,
LTC_VTR ± Offset1, LTC_VTR ±Offset2.
|
Thus the module VL makes four internal times available, which are synchronized by an external LTC. With
an offset = 00:00:00:00 the read time information is regenerated frame accurately.
|
| Two other independent free running counters are available as separate time information. These counters
can be configured as initial starting values, and be controlled by external Start / Stop / Reset / Set signal(s).
|
Not only can MTD timers be decoded; any date information can be identified and converted. Thus, different
times are available internally and can be configured to be outputted as LTC time information, LTC userbits or as serial data
strings in a selectable protocol format.
|
The configuration menus can be accessed with a PC. Selectable interfaces are a standardized USB port, or an
ethernet port (available in combination with an IE module).
SNMP and status monitoring is accessible at any time.
