Configuration and display functions
The MRV365 supports configuration file readback, program copying and a pre-stored picture. It also supports high grayscale and high refresh rate operation; this listing does not specify a numerical refresh rate or grayscale level.
The original product information describes the MRV365 as supporting the functions of the MRV320 with added MOM support. When replacing a receiving board, confirm the cabinet wiring, module interface and configuration file before installation. The different data-output modes listed above should be checked against the intended module configuration.

MRV365 FAQ
What resolution does one MRV365 receiving card support?
The listed single-card resolution is 256 × 226 pixels. Confirm the module configuration and required output mode for your cabinet before selecting a replacement.
How many data groups can the MRV365 output?
The specifications list 16 RGBR groups, 20 RGB groups or 64 serial data groups. These describe the supported output configurations, rather than a combined total.
What does MOM do on the MRV365?
Memory on Module stores calibration coefficients and LED panel information, helping retain the data associated with the panel.
Can I read back the MRV365 configuration?
Yes. The listed functions include configuration file readback and program copying. Keep the existing cabinet configuration available when planning maintenance.
Can the MRV365 replace an MRV320?
The product information states that MRV365 supports MRV320 functions and adds MOM. This functional description alone does not establish compatibility with every cabinet; check the wiring, module interface and configuration before replacement.
