Routing Switchers Tips and Tricks
General
The current version of Miranda’s Router Control Software supports serial, TCP/IP, and UDP/IP
communications connections. There are several general considerations regarding routing
switcher configuration.
If there is a choice between an RS-232 port and an RS-422 port, preference should be given to
the RS-232 port in order to avoid cabling problems. If RS-422 is used be careful of the pinouts
– please check thoroughly.
If the router can be configured to operate at different baud rates, in most cases the fastest
setting should be used, unless a recommended baud rate is specified in your router’s manual
or in this document.
If the software cannot detect the levels, then it is necessary to attach a standard PC through a
serial port, run HyperTerminal, switch some crosspoints from a physical control panel and
check if there is any communication over the serial port. In some cases it is necessary to enable
reporting over the serial port.

Network Compact Protocol (Default Driver for VikinX Compact Routers)
Every VikinX Compact router is equipped with a RS-232 port. Although the panels are
equipped with the port as well, it is not recommended to use it. It is possible to use a standard
straight-through

modem cable with a gender-bender. Most of the routers are using baud
rate 19200, but there are certain exceptions, so it is necessary to check the manual for your
particular model. Other port settings are 8 bits, no parity, 1 stop bit, and no flow control. The
DIP switches on the back of the router and the frame type define the address of the frame.
Type the value set by the DIP switches in the Frame ID box when you define your levels in
Miranda’s Router Control Software.
The Network protocol supports two types of frames: video and audio. Telecom routers act like
a video frame and the RS-422 Data router can be configured by DIP switches to work either as
video or as audio. Please refer to your device’s user manual for more information.
Troubleshooting
The Network Compact protocol is a binary protocol. For each crosspoint on each level the
router sends 3 bytes to the serial port. It means that you will see some kind of pseudographics
in your HyperTerminal window.
