The RCM2200 is also designed to accept 128K to 512K of flash EPROM packaged in a TSOP case. NOTE: Rabbit recommends that any customer applications should not be constrained by the sector size of the flash EPROM since it may be necessary to change the sector size in the future. -
Page 34: Other Hardware
4.5 Other Hardware 4.5.1 Clock Doubler The RCM2200 takes advantage of the Rabbit 2000 microprocessor’s internal clock dou- bler. A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 22.1 MHz frequency is generated using an 11.0592 MHz crystal. The clock doubler is disabled automatically in the BIOS for crystals with a frequency above 12.9 MHz. -

Page 45: Running Tcp/Ip Sample Programs
6.2 Running TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require that the user connect his PC and the RCM2200 board together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet. - Page 46 RCM2200 board. You will also need the IP address of the nameserver, the name or IP address of your mail server, and your domain name for some of the sample programs. RabbitCore RCM2200...

Page 47: Ip Addresses Explained
6.3 IP Addresses Explained IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods, for example: 216.103.126.155 10.1.1.6 Each decimal number must be between 0 and 255. The total IP address is a 32-bit number consisting of the 4 bytes expressed as shown above. A local network uses a group of adja- cent IP addresses. -
Page 48: How Ip Addresses Are Used
IP addresses are arbitrary and can be allocated as desired provided that they don’t conflict with other IP addresses. However, if they are to be used with the Internet, then they must be numbers that are assigned to your connection by proper authorities, generally by dele- gation via your service provider. RabbitCore RCM2200... -
Page 49: Dynamically Assigned Internet Addresses
6.5 Dynamically Assigned Internet Addresses In many instances, there are no fixed IP addresses. This is the case when, for example, you are assigned an IP address dynamically by your dial-up Internet service provider (ISP) or when you have a device that provides your IP addresses using the Dynamic Host Configu- ration Protocol (DHCP). -
Page 50: Placing Your Device On The Internet
You can either place the RCM2200 directly on the Internet with a real Internet address or place it behind the firewall. If you place the RCM2200 behind the fire- wall, you need to configure the firewall to translate and forward packets from the Internet to the RCM2200. RabbitCore RCM2200... -

Page 77: Appendix C. Power Supply
The RCM2200 does not have a battery, but there is provision for a customer-supplied bat- tery to back up SRAM and keep the internal Rabbit 2000 real-time clock running. Header J5, shown in Figure C-1, allows access to the external battery. This header makes it possible to connect an external 3 V power supply. -
Page 78: Reset Generator
Figure C-2. RCM2200 Battery-Backup Circuit C.1.2 Reset Generator The RCM2200 uses a reset generator, U1, to reset the Rabbit 2000 microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 4.50 V and 4.75 V, typically 4.63 V. The RCM2200 has a reset output, pin 9 on header J5. -
Page 79: Chip Select Circuit
C.2 Chip Select Circuit The RCM2200 has provision for battery backup, which kicks in to keep VRAM from dropping below 2 V. When the RCM2200 is not powered, the battery keeps the SRAM memory contents and the real-time clock (RTC) going. The SRAM has a powerdown mode that greatly reduces power consumption. - Page 80 RabbitCore RCM2200...
