Slave Control API

API that connects the master and slave device by using the RS-485 network. The v2 devices will now work as a dummy reader when set as a slave device. It will not store any kind of information for user and all will be stored inside the master device. The slave device will send the information scanned, and the matching and access rule check will be done from the master device. The slave device will only receive the result.

Caution

When the SDK is initialized, there are no information about the slave devices. Therefore, a slave device must be searched or added before controlling.

   • If no device is connected to a particular channel, it has a 0 indicating that it can be connected even if it is a Suprema device or an OSDP device.

   • If a Suprema device is connected to a specific channel, only Suprema devices are allowed to connect to that channel, and channelType has a value of 1. The OSDP device is ignored even if it is connected.

   • If an OSDP device is connected to a specific channel, only OSDP devices are allowed to connect to that channel, and channelType has a value of 2. The Suprema device is ignored even if it is connected.

   • Each channel of CoreStation40 can be mixed and operated as Suprema device channel and OSDP device channel.

   • The maximum number of OSDP devices allowed to connect to a channel is limited to 2, and if the channel is already maxed out, the channelType will be 3, indicating that no more connections are allowed.
