Rane RPM 44 Скачать руководство пользователя страница 6

Manual-6

The cable length limitations and the maximum number of 

remotes that can be powered from the RPM 44 is limited by the 

mix of remote types used, the cable type used, the distance to 

each remote, and the wiring configuration. Detailed wiring and 

cabling tables and several examples are discussed in the SR 2, SR 

3 and SR 4 Manuals. Up to eight SR 3 remotes can be powered 

directly from the RPM 44.

The RW 485 port is intended to be used with Rane’s Smart 

Remotes only; we do not recommend directly interfacing the 

RW 485 port with devices that are not compliant with the TIA/

EIA-485 standard, such as the “485” ports found on AMX and 

Crestron devices.

AMX and Crestron Control

There are two ways to control a Drag Net device from an 

AMX or Crestron system. Use either Ethernet connectivity or 

use the rear panel Versatile Input Port (VIP). Each of the 8 VIP 

pins supports either switch closure Preset recall or zero-to-five 

volt control of Level. 

The RW 485 ports found on some Drag Net devices 

do not

 

communicate with AMX or Crestron systems. They are solely for 

communicating with Rane's RW 485 remotes.

Many AMX/Crestron applications require simple Level con-

trol and/or Preset recall. This is most easily accomplished using 

the VIP (Versatile Input Port) found on all five Drag Net de-

vices: RPM 2, RPM 26z, RPM 22, RPM 44 & RPM 88. There 

are always more Drag Net products coming — both hardware 

and software, so check our home page for the most recent.

VIP Preset Recall

Connect a switch closure or relay to a VIP pin and short it to 

the ground (GND) pin to recall the corresponding Preset. For 

example, shorting VIP pin 1 to the GND terminal recalls Preset 

1; pin 2 recalls Preset 2, etc. There are more details about this 

functionality in the Drag Net Help file and on our Drag Net Ap-

plications page. Be certain to appropriately set the VIP Alloca-

tion in Drag Net's Parameter Window.

If GND contention of two or more pins simultaneously 

occurs, the highest-numbered VIP pin takes precedence. For 

example, if pin 3 is shorted to GND and pin 6 is then shorted 

to GND, Preset 6 is recalled. If pin 3 is closed and then pin 2, 

nothing happens -- Preset 2 is 

not

 recalled. This permits a hier-

archy of Presets when using VIP pin closures for tiered priority 

paging. Since there are only eight VIP pins, you can only recall 

up to eight Presets using switch closures.

There are four ways to recall more than eight presets. 

1. Use the Drag Net software Recall button which is only in-

tended for the system installer/designer.

2. Use the Rane SR 4 remote to recall any eight Presets.

3. Use a Rane SR 3 remote which can recall any 16 of the avail-

able 24 Presets.

4. Use an Ethernet command from an AMX or Crestron Ether-

net-equipped product.

[When using Drag Net's Auto Mixer/Ducker block, you have 

the ability to link a VIP pin closure to a push-to-talk switch in a 

paging or boardroom application. When using the Ducker block 

in these applications, the VIP pins act independently provided 

you Group the appropriate VIP pin with the Auto Mixer/Duck-

er's Input in Drag Net's Remote Map. Again, see our Drag Net 

Applications for examples.]

VIP Level control

Connect a zero to five volt DC voltage to a VIP pin from an 

AMX or Crestron card to adjust any or all Level blocks placed in 

the Processing Map. Use Groups in Drag Net's Remote Map to 

link one or more Level blocks so they track each other when us-

ing a VIP pin. Be certain to appropriately set the VIP Allocation 

in Drag Net's Parameter Window. When using VIP pins with 

Level blocks, set the minimum and maximum for each Level 

block by double-clicking it while it's in a Remote Map Group. 

This keeps the max and min burdens within the Drag Net device 

— but only when using the VIP pin to control Levels, not when 

adjusting Levels from Ethernet commands.

You can use up to eight voltage control inputs linked to 

Level(s) using the rear panel VIP pins. Combinations of Preset 

switches & voltage Level “pots” are possible as long as combined, 

they do not exceed the eight pins provided.

Since you can Group any or all Level blocks in Drag Net's 

Remote Map, it's much easier to implement a stereo level control 

since the Drag Net device is burdened with the task of tracking 

many Levels. You can use this to your advantage when using VIP 

pins to adjust multiple zones or levels. Since you can place the 

Level block anywhere within the Drag Net Processing Map, you 

can Group Level blocks at the input, at the output or anywhere 

in-between — just place the Level block where you want it.

Ethernet Port

The Ethernet port is used to configure, monitor, and control 

the RPM 44 via standard 10Base-T Ethernet communication. 

Use an Ethernet crossover cable (one is included with each unit) 

to connect the RPM 44 directly to a computer. Use a standard 

(non-crossover) Ethernet cable if the RPM 44 and computer are 

connected indirectly using an Ethernet repeater hub or switch.  

All devices connected to the Ethernet port, including 

repeater hubs, switches, and the computer’s Network Interface 

Card (NIC) must support 10Base-T communication.
