REMOTE CONTROL OF THE ROUTERS
Sections 5.1 and 5.2 provide documentation on two different serial remote control protocols that can be
used to control the X0401 series routers. Section 6.1 describes the control of the router crosspoints using
SNMP with
VistaLINK
®
or the X-NCP2 Router control panel.
5.1.
GVG TEN-XL ASCII PROTOCOL
The following sections are provided as a technical reference for programmers who want to write their own
software to control the Evertz X0401 series routers using the GVG TEN-XL ASCII command protocol.
There are some hardware differences between the X0401 series routers and the Grass Valley TEN-XL
routers, which have required differences in implementation of the protocol for the X0401 series routers.
When the X0401 series router is operating in the
master
mode, it will send out commands to the router
that matches its
serial address
. When the X0401 series router is operating in the
slave
mode, it will only
respond to commands that match its
serial address.
If two X0401 series routers are connected in a
master/slave configuration, then the address of both routers must be set the same.
The
Setup Menu
in the router must be used to configure the
REMOTE CTL
port. See section 3.14 for
information about configuring the serial port.
5.1.1. Serial Data Format
In GVG’s TEN-XL ASCII protocol all words sent and received use the following format:
Standard:
RS-232 (Can be set to RS-422 by changing internal Jumpers)(See section 2.4.2)
Data Rate:
Default 38400 Baud (Can be set using the
Baud Rate
menu item).
Data Format:
Default 8 data bits, even parity, 1 stop bit (Can be set using the
Serial Format
menu item).
5.1.2. Definitions
1.
GVG’s TEN-XL ASCII protocol uses standard ASCII hex codes for the transmission of commands.
Programmers must use the hex equivalent code in order to successfully convey commands from
their controlling software to the X0401 series router. Hexadecimal [hex] numbers are represented
with the prefix “0x.”
i.e. decimal “14” = “0x0E.”
2.
There are two reserved words in GVG TEN-XL ASCII Protocol. They are illustrated in the table
below.
Reserved Word
Hexadecimal Equivalent
Control Character
STX
0x02
^B
ENQ
0x05
^E

4. Internal crosspoint numbers are ‘zero-based’, meaning that crosspoint number 1 is accessed as
source 0. Since GVG TEN-XL protocol is based on 10 internal crosspoints and the Evertz 4 x 1
