3.6.2 Remote Interface Specification
Refer to Appendix B for remote control operation information.
3.6.2.1 Remote Baud Rate
The remote communications baud rate and parity are programmed by the front panel
control in the Utility System menu (refer to Chapter 4). The programmed baud rate and
parity are maintained indefinitely by use of the EEPROM on the M&C module. The
parity bits can be set to EVEN, ODD, or NONE (with 8 data bits). The available baud
rates (bit/s) are listed below:
•
110
•
150
•
300
•
600
•
1200
•
2400
•
4800
•
9600
•
19200
3.6.2.2 Remote Address
To communicate with the established remote communications protocol, each modem
must be configured for one address between 1 and 255. Address 0 is reserved as a global
address that simultaneously addresses all devices on a given communications link. Each
modem on a common remote communications link (RS-485) must have a distinct
address.
The addresses are programmed by front panel control in the Utility System menu and
maintained in EEPROM.
