15 Kramer Protocol
USection 15.1U describes how to switch between Protocol 3000 and Protocol 200037F
1
.
USection 15.2U defines Protocol 3000. USection 15.3U defines Protocol 2000.
By default, the VP-88K is set to Kramer’s protocol 3000, but it is also compatible
with Protocol 2000.
15.1 Switching Protocols
You can switch protocols either via the front panel buttons (see
USection 15.1.1U) or
by sending protocol commands (see
USection 15.1.2U).
1 You can download our user friendly “Software for Calculating Hex Codes for Protocol 2000” from the technical support section on our
