Configurator Serial Protocol Table
5−28 VM 3000 Installation and Operating Manual
Notice that the standard setting for a Model 200 switcher is 38.4 kbaud; this is the recommended data rate. The
communication standard is RS−422; parity is automatically set to “even.” For the production switcher, protocol
setting is described in the Model 200 Peripheral Interface II manual as follows:
“Communication can follow the RS−232 or RS−422 standard at 9.6K, 19.2K or 38.4K baud with even, odd,
or no parity. Switcher Setup Function #5 PERIPH COMM permits selection of these communication parame-
ters. This function can be accessed by connecting the Diagnostic Pod to the State Processor connector on the
521 Control Module and entering Setup mode #5.”
†
The protocol must be exactly the same for all devices on the Peripheral Bus. Refer to the production switcher instal-
lation manual for additional installation and operating instructions.
ASC (ASCII) refers to switcher control using an external computer. Hardware connections are described on page 2−85.
For Diamond−ASCII, the baud rate must match the hardware setting on the DD production switcher XBAR port (nor-
mally 38400) (see page 2−81). A technical description of the Grass Valley ASCII computer interface protocol is pres-
ented in Appendix N.
ALP (Alpha Image), DTK (Datatek D−2000/2166), TEN (GVG 102), HRZ (GVG Horizon), MVD (Microvideo),
NVT (Novotronic), NXS (Nexus), U12, U96, and VTK (Vistek) all refer to VM 3000 boards controlling one or more
of these “remote” (third party) switchers. U12 is for 1200 baud connection to a Utah AVS−1B with PL−320; U96 is for
9600 baud connection to a Utah UDI−1B. When selected, this entry will apply to VM/SI odd−numbered ports only. (Hard-
ware installation of these switchers is discussed on page 2−12.)
Note: Pro−bel switchers use the “AlphImag” protocol.
CET SMPTE ES Tributary protocol. For CM 4000 applications only. This is the full tributary ESBus automation proto-
col, compliant with SMPTE EG 29−1993, and all associated normative references.
DEC is a custom protocol.
DIM (Diamond) is the protocol used to return mnemonic information to a DD Series production switcher serial port.
The baud rate must match the Diamond hardware setting (normally 38400) (See page 2−81).
DUN is for Dune digital audio switchers. When selected, this entry will apply to VM/SI odd−numbered ports only.
ES (ESbus) is for VM/SI 3000 boards controlling a EBU/SMPTE ESbus−compatible VTR (such as the Philips
DCR−500) or similar machine, or, for a customer−supplied computer program controlling such VTRs.
ESC (ESbus control) is for VM 3000 boards controlling a “remote” (third−party) routing switcher using the proposed
ESbus routing switcher dialect. When selected, this entry will apply to VM/SI odd−numbered ports only. (For a descrip-
tion of this protocol, please contact Grass Valley.)
ESW (ESswitch) This is a simplified version of the ESbus Tributary protocol. When selected, this entry will apply to
VM/SI odd−numbered ports only. This protocol allows a Grass Valley Crosspoint Bus router
‡ to be controlled by a
Philips Broadcast Automation or third−party computer. Hardware connections are described on page 2−83 (Automa-
tion) and 2−85 (other systems). For a description of this protocol, please contact Grass Valley.
ESP (ESbus Physical) is a protocol used for “physical” switching where the control system selects physical inputs and
physical outputs on logical levels. (Note: This is not the same as File Server controlled physical switching, as described
on page 14−1.) For a description of this protocol, please contact Grass Valley.
