Limit bending of cables
No installation cables should be bent beyond their rated bend radius. Cables should gradually bend around corners
where possible. Bending cables beyond their rated bend radius can alter their impedance and permanently damage
the cable.
Run cables far away from interference sources
Cables should be run far away from potential interference sources such as radio frequency (RF) emitters. The
distance required is dependent on the strength of the interference source.
Removing a cable from a BNC port:
• align the slots on the cable’s connector with the bumps on either side of the BNC port
• if not rack mounted, use one hand to hold the GridTime 3000 in place
• gently slide the cable’s connector over the port
• gently twist the cable’s connector clockwise to fasten it in place, ensure the bumps on the BNC port are fully
pushed down into the cable’s connector slots.
Removing a cable from a BNC port:
• If not rack mounted, use one hand to hold the GridTime 3000 in place
• gently twist the cable’s BNC connector counterclockwise to release it
• gently slide the cable’s out of the port

RJ-12 Serial String Ports
This section describes how to form a connection to the GridTime 3000's RJ-12 ports.
The GridTime 3000 features two RJ-12 serial string output ports:
• the RS-422 port — uses RS-422 transmission (Port 11)
• the RS-232 port — uses RS-232 transmission (Port 12)
Each port can be configured to output its own ASCII time code string from a list of supported strings. See
for a complete list of these strings.
The ports are standard RJ-12 receptacles.
The pinout of the RS-232 port is given in
