configure & control the wall clock itself. This section provides describes the connection options to the

device. The key sections are the following:

Time Code connections

Allows input and output connect connectivity to time codes.

Ethernet Connection

Allows operation and configuration of the device through a NMS (VL-PRO).

Serial Port connection

Allows configuration of the device through the RS-232 or Serial Port.

2.2.1. Time Code Connectors

There are two LTC IN and LTC OUT connections available in the rear of the device.

IN+, IN-

These two input pins are for connecting SMPTE/EBU longitudinal timecode

(LTC) to the clock.

OUT+, OUT-

These two input pins are for connecting SMPTE/EBU longitudinal timecode

(LTC) to the clock. They are a loop thru from the IN+ and IN- pins.

2.2.2. Ethernet Connections

The 1275T/1285T is designed to be used with either 10Base-T (10 Mbps) or 100Base-TX (100 Mbps)

also known as Fast Ethernet, twisted pair Ethernet cabling systems. When connecting for 10Base-T

systems, category 3, 4, or 5 UTP cable as well as EIA/TIA – 568 100  STP cab

connecting for 100Base-TX systems, category 5 UTP cable is required. The cable must be “straight

through” with a RJ-45 connector.

The straight-through RJ-45 cable can be purchased or can be constructed using the pinout information

in Figure 2-2. A colour code wiring table is provided in Figure 2-2 for the current RJ 45 standards

(AT&T 258A or EIA/TIA 258B colour coding shown). Also refer to the notes following the table for

INSTALLATION Revision 1.0 Page - 5

Note the following cabling information for this wiring guide:

• Only two pairs of wires are used in the 8-pin RJ 45 connector to carry Ethernet signals.

• Even though pins 4, 5, 7 and 8 are not used, it is mandatory that they be present in the cable.

• 10BaseT and 100BaseT use the same pins, a crossover cable made for one will also work with the

other.

• Pairs may be solid colours and not have a stripe.

• Category 5 cable must use Category 5 rated connectors.

The maximum cable run between the 1275T/1285T and the supporting hub is 300 ft (90 m). The

maximum combined cable run between any two end points (i.e. 1275T/1285T and PC/laptop via

network hub) is 675 feet (205 m).

Devices on the Ethernet network continually monitor the receive data path for activity as a means of

checking that the link is working correctly. When the network is idle, the devices also send a link test

signal to one another to verify link integrity. The 1275T/1285T rear panel is fitted with two LEDs to

monitor the Ethernet connection.

10/100

This Amber LED is ON when a 100Base-TX link is last detected. The LED is OFF when a 10Base-T

link is last detected (the LINK LED is ON). Upon power-up the LED is OFF as the last detected rate is

not known and therefore defaults to the 10Base-T state until rate detection is completed.

LN/AC

This dual purpose Green LED indicates that the 1275T/1285T has established a valid link to its hub,

and whether the 1275T/1285T is sending or receiving data. This LED will be ON when the

1275T/1285T has established a good link to its supporting hub. This gives you a good indication that

the segment is wired correctly. The LED will BLINK when the 1275T/1285T is sending or receiving

data. The LED will be OFF if there is no valid connection.

2.2.3. Serial Port Connections

COM This female 9 pin D connector is used for connecting a computer to upload firmware to the

1275T/1285T. It is also used as a diagnostic port for troubleshooting. See section 6 for

information on upgrading the firmware.
