Category : product
EZL-50M had introduced for replacing EZL-50R which was discontinued.
1. Used Hardware
EZL-50R (including EZL-50 and 50A) used 8051 series as its CPU. On the other hand, EZL-50M uses AVR series.
2. Size of Serial Buffer
In case of serial buffer for receiving, EZL-50R has 8 KB and EZL-50M has 17KB.
3. Timing for Sending TCP data
EZL-50R checks the serial buffer every 20 ms. if there are data in the buffer, 50R sends the data to the network. On the other hand, EZL-50M waiting 10~20 ms after the last data had received. During that time, if any data has come, it sends data in the buffer to the network.
4. Maximum Baud Rate
EZL-50R supports 230,400 bps and EZL-50M supports 115,200 bps.
5. RTS operation
If you don't use Flow control option(RTS/CTS), EZL-50R keeps RTS pin Active. However, the RTS pin of EZL-50M operates regardless of activating or inactivating flow control option.
6. Network RXD LED
RXD LED of EZL-50R blinks with sending data as well as receiving data. 1.1i or the older versions of EZL-50M's firmware operated same way, but it was corrected after 1.1J version.
