Specification of the MAIN4 PC Board

		Hardware			Software
Model	Flash ROM	RAM	Kanji ROM	Kanji Font	Registry	Program
			(IC7)		area size	area size
B-SX5T-TS22-QM-R		16MB → 32MB
B-SX4T-GS20-QM-R		8MB → 16MB	None		896KB	2304KB
SP40II-R	4MB → 8MB	8MB → 16MB			↓	↓
B-SX5T-TS22-CN-R		16MB → 32MB	None → 8MB	Simplified	3072KB	4096KB
B-SX4T-GS20-CN-R		8MB → 16MB		Chinese

Except for the memory capacity, the specification of the MAIN4 PC board is equivalent to that of the MAIN3 PC board. However, the firmware V5.0 and greater (Main program V5.0, Boot program V3.0) is installed into the MAIN4 PC board only.

jProtocol

„XON/XOFF (DC1/DC3) protocol

•When initialized after power on, this printer becomes ready to receive data and sends an XON code (11H). (Transmission or non-transmission of XON code is selectable by means of the parameter setting.)

•The printer sends an XOFF code (13H) when the free area in the receive buffer becomes 10K Bytes or less.

•The printer sends an XON code (11H) when the free area in the receive buffer are 512KB or more.

•When there is no free area in the receive buffer, the printer discards received data which exceeds the receive buffer capacity without storing it in the buffer. (After detecting the XOFF code, the host computer must stop transmission before the printer receive buffer becomes full.)

•The printer sends an XOFF code (13H) at power off time. (Transmission or non-transmission of XOFF code is selectable with the parameter setting.)

•The DTR signal is always “High” level (Ready).

•The RTS signal is always “High” level (Ready).

„READY/BUSY (DTR) protocol

•When initialized after power on, this printer becomes ready to receive data and converts the DTR signal to "High" level (READY).

•The printer converts the DTR signal to "Low" level (BUSY) when the free area in the receive buffer amount to 10K bytes or less.

•The printer converts the DTR signal to "High" level (READY) when the free area in the receive buffer amount to 512KB or more.

•When there is no free area in the receive buffer, the printer discards received data which exceeds the receive buffer capacity without storing it in the buffer. (After detecting a BUSY signal, the host computer must stop transmission before the printer receive buffer becomes full.)

•The RTS signal is always “High” level.
