Rane Via 10 - Manual (Page 7)

RaneWare RW 232 Ethernet operation. Run RaneWare
(2.10 or higher) and from the System menu, select System
Setup. In the Connection box, select the Via 10 (Ethernet)
radio button so RW 232 commands will be sent out of the
Ethernet port (rather than out the PC’s RS-232 COM port nor
out the computer’s modem and phone line to a far end modem
and Rane’s RPD 1). Make sure to type the proper Via 10 IP
address for the RaneWare RW 232 device(s) you wish to
control over the network. Each Via 10 can accept up to 16
RW 232 devices in any variety connected to its RS-232 port.
To address more RW 232 devices, use additional Via 10s.
Generic RS-232 use. RS-232 based serial devices can
transport their data through the Via 10 as long as the Via 10’s
RS-232 port is configured properly. The default settings for
the Via 10 RS-232 port are shown above. Supported ranges
for RS-232 communications can be found in the
VIACONFIG
utility. The pull down fields display all supported settings.
For detailed RS-232 port specifications, see the Data Sheet
section of this Manual.
Standard RS-232/DB-9 wiring for Tx and Rx connections
are provided. The maximum cable length supported by RS-
232 is still 50 feet (15 meters); this assumes good quality,
CAT 5 cable.
A variety of external means are available to lengthen the
50 feet limitation by using RS-232 to RS-422 or RS-485
converter devices. These can be sourced from a variety of
manufacturers (but not Rane – we can’t make everything,
where would we put it? [OK, this is a Steven Wright joke, but
a good one]). At this point, we’re compelled to ask: doesn’t it
seem strange to have to mention such devices when your
system already includes 100 meter-capable Ethernet for
control?
Hardware 2: RS-485, the Rane SR 1L and SRM 66
SR 1L Use. This Rane accessory is a generic RS-485
device. Though an accessory for the Rane SRM 66 Splitter
Router Mixer, SR 1L’s can be used independently for a
variety of applications. See Software and Applications on
page Manual-8.
Up to seven SR 1L Smart Remotes can be wired directly
to the Via 10 RS-485 port in any combination of daisy chain
or star configuration. Use CAT 5 cable (two twisted pairs plus
a shield) and double check the wiring since this is often the
cause of baldness (i.e., pulling our collective hair out debug-
ging problems). Only the most distant SR 1L connected to the
Via 10 should have its R
T
switch ON, which connects a 150
ohm terminating resistor.
SRM 66 Use. The SRM 66 contains an RS-485 port
(called RIP for Remote Interface Port) which may be wired to
the Via 10’s RS-485 port for SRM 66 control over a LAN;
however, you cannot connect both an SRM 66 and SR 1L
remote(s) to the same Via 10—one device per RS-485 port.
Do not connect the V+ terminals together—connect A to A, B
to B, V– to V– and shield to shield.
RS-485 remote power. The Via 10’s RS-485 port
includes a low current, 8 VDC supply which is required for
SR 1L operation, but can be used for powering other low
power peripheral devices. The data sheet (in this booklet) lists
the specifications for this small power source, including its
current capabilities.
Generic RS-485 Use. Use CAT 5 cable for connection to
the RS-485 port. The balanced data connections can drive up
to 100 meters of cable when properly terminated with 150
ohms to obey the standard and ensure trouble-free operation.
Hardware 3: Versatile Input Port (VIP)
The VIP provides the perfect place to connect memory
recall switches, potentiometers, temperature sensors and other
instrumentation and/or logic devices. Each of the eight inputs
accepts 0 to 5 VDC and includes a true 8-bit A-to-D converter
providing 256 steps; (it’s actually a 10-bit converter that is
rounded to an 8-bit word length). You can therefore use each
of the eight VIPs as independently programmable compara-
tors, ratiometric controls or instrumentation inputs. A current-
limited (100 mA max) internal voltage reference of 5 volts
(Vref) is supplied. Each port includes a 100k ohm pull-up
resistor to Vref and a 2
nd -order, 15 Hz Butterworth low pass
averaging filter. Any range of potentiometer values and tapers
can be used as long as the 100 mA current limitation is not
exceeded. Either momentary or position-sensitive switches
can be used; use whatever is appropriate or easiest for your
application and its software setup requirements. Any instru-
mentation output with a 0 to 5 VDC range can be used with
the VIP. The VIP update rate is dominated by the network
transmission speed and is read each time the VIP data is
requested using the
Via10VIPX ActiveX control (see page
Manual-9).
