2. I/O’s Description and Cable Requirements
2.1 AC POWER
Universal power input, accepts 100 to 240 VAC.
Connector: IEC inlet - Fuse: 5A 125VAC 5X20MM
☛ Use an IEC power cable and connect to an 100/240 AC wall outplet.
2.2 ANTENNA (OPTION)
This port is used to connect an external GPS antenna (GPS option).
Connector: SMA jack
☛ Use 50Ω coaxial cable with an antenna as specified in the instructions
manual provided with the GPS option.
2.3 RS-232 / GPIO / TC OUT / 1PPS I/O
This mutifunction connector is used for connecting an external GPS receiver
(RS-232 & 1PPS), GPIO and balanced TC outputs.
Connector: DB-25 female receptacle
☛ Use a custom DB-25 cable per the pin out described in appendix G
2.4 HD/SDI (OPTION)
Connectors: BNC IN + BNC Loop Through
☛ Use standard 75Ω BNC coaxial cables (see DXD/SDI manual).
2.5 ETHERNET PORTS
4 independant Gb Ethernet ports used to connect the DXD-16 to a network for PTP
sync or to control the unit remotely and upload firmware from any computer on
the network. Remote control and firmware update is from port 4 only.
Connectors: RJ45 jack
☛ Use a standard cat5 or cat6 Ethernet cable with RJ45 plugs.
2.6 REFERENCE INPUTS & TERMINATION SWITCHES
The 2 BNC inputs accept WC, AES, Video Sync and 10MHz based on
the user selection (see Appendix A for a list of supported HD & SD video
formats). 10MHz is a sine wave typically 1/2 v, coming from a GPS receiver,
a rubidium clock or other types of generators.
Connectors: BNC
☛ Use standard 75Ω BNC coaxial cables.
Each input has a 75Ω termination switch. Under normal conditions, it should be
on. However, if a ‘T’ BNC is used to ‘daisy-chain’ the reference to another unit
(not recommended), termination should be off on the DXD-16. The last unit in
the chain, and only that unit, should have its termination on.
2.7 UNIVERSAL OUTPUTS
The 16 universal outputs can generate Word Clock, AES, 10MHz (1v pk-pk sine
wave), HD Video Sync, or SD Video Sync, based on the user selection.
Connector: BNC
☛ Use standard 75Ω BNC coaxial cables.
2.8 DC POWER
The DXD-16 can also be powered by a 12VDC @ 48W source. Acceptable range
is 11VDC to 17VDC.
The DC source can be connected together with the AC source for redundancy.
To order a DC power supply (p/n PS-8), contact your dealer.
Connector: 4 pin circular connector
☛ Insert the 4 pin plug into the rear panel jack and secure by screwing the ring.
Plug the supply into the wall using the standard IEC cable supplied.
3. Installation
3.1. UNPACKING
When unpacking your DXD-16 the following items should be in the shipping carton:
• DXD-16 unit
• IEC power cable
• Registration card
3.2. INSTALLING THE DXD-16
The DXD-16 is designed to be mounted in a standard 19” rack. It requires 1U in
height. Usual precautions should be respected when wiring the DXD-16: use high qual-
ity cables with good shield to guarantee a good signal transmission. Keep your cables
as short as possible. The type of cables required are specified in chapter 2.
To preserve the integrity of the transmission line, it is recommended that you do not
‘mult’ a single output to multiple devices as it can degrade signal quality.
The reference input needs to be properly terminated. If the DXD-16 is the last device
in the chain, turn on the 75Ω termination switch on the rear panel. If you are looping
through using a ‘T’ connector (not recommended), turn off the termination switch and
make sure there is a 75Ω termination at the end of the chain.
