Block R913B1
The APD block R913B1 is designed to receive and transmit telecode information in the T-235-1L equipment codes, receive information in the ASPD-U equipment codes, work on open radio data transmission channels formed by R-168-25U-2 radio equipment and on wired communication channels . The number of transmitting channels - 1 (PRD1). The number of receiving channels - 2 (PRM1, PRM2). PRD1, PRM1 work in the algorithms of the equipment T-235 1L at the junction of C1 FL. PRM2 works in the algorithms of the T-235-1L equipment (at the junction of C1 FL or at the junction of C1-PM) or in the algorithms of ASPD.

JSC SozvezdieDescription
Voltage levels of the output signals of the transmitter: 0.65V-0.95V via channel C1-FL (radio); 0.26V-0.46V through the channel C1-FL (wire).
Exchange rate via communication channels:
- 1200 bps - when working in algorithms T-235-1L at the C1-PM junction;
- 2400 bps, 4800 bps, 9600 bps - when working in algorithms T-235-1L at the C1-FL junction;
- 234 bps, 468 bps - when working in ASPD-U algorithms.
The block provides exchange with a computer via two RS 232C interfaces (COM1 and COM2).
The block implements an asynchronous start-stop mode of the RS 232C interface with the following main parameters:
transmission speed - 115200 bps;
the number of information bits in the package - 8;
the number of stop bits is 1;
no parity check;
data is transmitted starting from the low-order bit.
The electrical parameters of the RS 232C interface signals comply with the requirements of GOST 23675 79.
The block provides continuous operation for 48 hours. The time between failures of the block is not less than 7000 hours. The voltage and field intensity of radio interference generated by the block should not exceed the values specified in GOST V 25803-83 for equipment of group 1.1.1. The mass of the block is not more than 3.3 kg. Overall dimensions of the block - (290 x 208 x 85) mm.
