There are 2 ports on the H-100 Control Panel, an RS-232 port and an RS-485. Each port can be reconfigured as to its
function, however there can only be one master Modbus port. All ports can have their baud rate, parity and stop bits
changed. For Modbus ports, the address can also be changed via GenLink, but each address in a connected system
must be unique. Normally the RS-232 port will be configured as a Modbus slave to communicate with GenLink and the
optional Modem. The RS-485 port will act as a master for connection to up to two remote annunciators/remote relay
panels and up to four HTSs. The RS-485 port can be reconfigured via GenLink to be a deep diagnostic port.
