7.4 MD MODE OPTION (Factory Installed)

7.4.1 MD Mode Description

The GEN supply is capable of operating in a multi drop environment - more than 1 supply conducting serial communications on a single serial bus. A maximum of 31 GEN supplies can operate in this sin- gle bus. Upon power up the Gen will enter the point-to-point mode in which it is assumed that only 1 supply will operate on a serial bus. MD Mode must be enabled - Ref. Section 7.10.2.2. The user must set all Slave supplies to a unique address. No two supplies may have the same address.

7.4.2 MD Mode enable – Serial communication mode

Refer to section 7.10.2.2. MD Mode is entered into via a Single byte command. In MD Mode the Mas- ter supply shall operate in one of the two serial modes, RS232 or RS485, depending upon the rear panel DIP switch setting and the Slave supplies shall operate in the RS485 serial mode.

7.4.3 MD Mode SRQ

In MD Mode the SRQ generated by the supply is replaced by a single byte SRQ sent two times in se- quence. The SRQ byte, in binary, will contain the address of the supply in the least significant 5 bits with bits 5 and 6 set to logic zero and bit 7 set to logic 1. Ref. Table 7-4.

7.4.4 Communication Collisions

In MD Mode it is possible to have one supply issue an SRQ while another supply is transmitting data/response to a command. When this happens, the HOST PC will receive garbled data and as- sume that the data/response was corrupted and thus re-send the command - the SRQ will probably be lost. The method of recovery will be SRQ retransmission, Ref. Section 7.4.5, or polling all attached supplies to see who issued the SRQ - available by reading the SEVE? Register.

7.4.5 MD Mode SRQ Retransmission

The supply can be commanded to retransmit the SRQ at regular intervals until it is answered to by the HOST PC (Ref. Section 7.10.2.4). The retransmission interval is 10 ms plus the supply address multi- plied by 20 ms.
