System Control I/O modules
are used in modular systems like the CommSync II, CommSync
II-D, GSync and GSync II to provide remote control and
monitoring. In addition, they accept external
synchronization input for DTF (Distribution Time and Frequency)
systems. Communication with the System Control modules is
via an RS-232 or Ethernet interface. Ethernet versions also
provide control and monitoring via the Zyfer Monitor GUI as
well additional functionality such as NTP, SNTP and PTP.

No.
RS-232 I/O Module with 1PPS BNC
Output -
Bi-directional RS-232 interface for remote control and monitoring. One 9 pin
DE-9 and two BNC connectors.
The DE-9 connector contains one RS-232 bi-directional
serial port and two hardware status output signals, (Alarm and
Ready). BNC connectors provide a TTL 1 PPS output. Two status LED's.
385-4005-01
RS-232 Module with 1 PPS & 1, 5 &
10MHz BNC External Inputs - External
synchronization input for DTF systems, one 9 pin
DE-9 and two BNC connectors. The DE-9
connector contains one RS-232 bi-directional serial port and two
hardware status output signals, (Alarm and Ready). BNC connectors
receive 0.7 Vpp to 10 Vpp sine or square wave reference inputs
from the user for DTF-based systems. Two status LED's.
385-4037-02
RS-232 Module with 1, 5 & 10MHz
Fiber Optic External Inputs - Provides a bi-directional RS-232
interface for remote control and monitoring and connections for
external synchronization input with a 9-pin DE-9
connector and two fiber optic connectors. The DE-9
connector contains one RS-232 bidirectional serial port and two
hardware status output signals, (Alarm and Ready), and Lock
inputs. Four status LED’s.
