Product Overview The CTS-HCOM Series is an integrated device that uses both RF communi-
cation in 2.4GHz and 5GHz and IR (Infrared light, optical) communication. It is capable of choosing the stable communication media depending on the surrounding conditions. This product is a communication device to transmit and receive 8-bit data contactlessly according to the SEMI-E84 protocol regulation. It is possible to set many comfortable additional functions by the serial port or the wireless communication. Also it is possible to change the communication media from IR to RF and vice versa, depending on the noise level of surrounding. Moreover, it provides various functions that find causes and solutions promptly when there are abnormalities in transmitted/received data during the communication. This device is mainly for the exchange of the control signals between the vehicle (Master or Active devices such as AGV/OHT) and the equipment (Slave or Passive devices). 2.

LED Display LED Name IN 1~8 Display Content Indicates the operation status of input circuit inside of PIO, which is ON when the input is LOW. OUT Indicates the output status inside of PIO, which is ON when TR is ON. Turns ON when there is data transmission/reception between a master and a slave PIOs. GO The maximum time that GO LED and output remain OFF after the wireless communication is disconnected is 775ms. This can be adjusted by user through <R> command. Used as watchdog signal to check whether there is an abnormality in the product. RF mode: Blinks with periods of Master mode (0.25 sec), STATE1) Slave mode (1 sec), standby mode (0.1 sec). IR mode : Similar to that of RF mode, but has different blinking periods. Operation modes are distinguishable. See the diagram below.

Major Pin Function Signal Name Usage Mode (Input) Input to select a mode of PIO GND : Slave Mode (EQ, Connected to GND inside of PIO so no additional connection is necessary.) OPEN : Master Mode (OHT) Select (Input) Input to operate the PIO GND : Stops a wireless communication of PIOs. OPEN : Operates a wireless communication of PIOs. GO (Output) Turns ON if there is a normal communication between a master and a slave PIOS. Modes Master Mode Transmits data from input port wirelessly if PIO is operated by OPENing the Select signal. This mode is used by OHT or AGV. Slave Mode Even though PIO is operated by OPENing the Select signal, does not transmit but only receives optical signals. Transmits data from input port wirelessly when receives optical signals from the master. This mode is used by equipment. 15 10. Communication Medium Selecting Method This product has two contactless communication media: the optical (infrared light) and the wireless communication (2.4GHz, 5GHz RF). There can be a communication interference in the semiconductor factories because of surrounding equipment or sensors. If this happens, this product provides a stable communication by selecting the other medium without an interference. A communication medium can be selected by the serial communication command
(M command). In case of wireless communication (RF), the distinct channel ID and other variables must be set. 16 11. RF Function RF Communication Characteristics RF communication using ISM (Industrial Scientific and Medical) Band of 2.4GHz and 5GHz that can be used without an authorization. High-speed data communication - 1Mbps per channel. GFSK modulation, 1MHz bandwidth. A great expandability provided by the function selecting the serial numbers of 6 bytes and frequencies of 3 bytes. Channel occupation time is about 1ms (Communication period: 25ms). Minimizes the interference between other wireless devices. Setting the channel without conflict is necessary because of the frequency interference with 2.4GHz and 5GHz wireless LEN and other wireless devices.

See the values as the relative values with error of measurement. Like the diagrams below, the reception sensitivity can be vary depending on the directions, even in such a short distance. This can influence the performance of RF communication. Therefore, check the optimal conditions for RF communication before the installation of PIOs. Damping Ratio

19 Precautions for Installation 1) Metals, mirrors and other objects existing in a space at the straight-line distance between two sensors reduce the communication performance. Remove the obstacles on the path if possible. 2) You can use it stably without communication errors when there is no interference with other wireless devices in an open space. 3) There may be no metals or other obstacles within a 60mm radius around this antenna. 4) There may happen frequency interference due to other RF devices around. Use this in an environment without frequency interference for stable operation. 5) Especially, when using this together with a device using a 5GHz band, allocate a channel by avoiding overlaps. 6) Maintain a 20cm or more interval between PIOs for equipment. Wireless Environment Setting The wireless communication (RF) function of CTS-HCOM Series can be simultaneously connected to many devices due to its characteristics. In order to communicate with one device (equipment), the ID and CH(channel) of the communication counterparty (For equipment, Slave PIO) shall be set before starting communication with the vehicle (OHT, Master PIO). The ID and CH setting is possible using serial communication commands. PIO Slave Master Setting Method Connect to PIO serial port => Set by a communication commands (ID and CH, transmission power etc.) The set data is stored in the memory, so it doesnt need to be set again even though power is turned OFF. Connect to PIO serial port => Set by a communication commands (No. of VHL/Communication Medium/ID/CH/PORT) In case of Select OFF(Communication Permitted) ON
(Communication Prohibited), the IC and CH are changed to defaults. The No. of VHL, communication medium, ID, CH, PORT must be reset before Select OFF. If it is not ready for data transmission, it does not transmit data even though it becomes Select OFF. For more information, see the Serial Communication Specification. 12. IR Function 20 IR Communication Characteristics Wavelength : 870nm (Infrared light, Optical) Ambient brightness : 4000lx or less of incandescent light and fluorescent light, the place without direct light Transmission/reception method : Half Duplex Modulation : Pulse Modulation Operational distance and angle : 0.5m at 0, 0.25m at 15 Adjustment of communication distance : Serial/RF communication command Adjustment of reception level : Serial/RF communication command
(To eliminate surrounding noises if any.) Input signals and GO output filtering : Is possible to set the time by the serial command. IR Radiation Characteristics As shown in the figure below, the communicable angle is 30, and communication is possible from a 0.25m away distance at 15 and from a 0.5m away distance at 0. If light, sunshine, IR remote controller, optical sensor, etc. applies light directly to the transmission/reception window, loss of communication may happen. In this case, block the external light and then use it. Unit : mm 21 Considerations for installation This product uses both IR and RF communication. In case of IR (optical and infrared light) communication, the performance declines if light is blocked by fixed brackets or parts since it uses invisible infrared light. As shown in the figure below, when PIOs of VHL stop without error or within the range of 15, surrounding objects shall not block the light of PIOs. Stop without error Stop at 15 degrees to the right Stop at 15 degrees to the left The cases of the light of PIO is blocked by the surrounding objects are shown in diagrams below. In these cases, there is high possibility of PIO communication error depending on where VHL stops. If a VHL stops without error, the PIO communication will operate normally. However, if it stops with error, communication error can happen becuse light is blocked. Therefore, be careful when install the fixed equipment and surrounding devices. Stop without error Stop at 15 degrees to the right Stop at 15 degrees to the left Also, if there is optical noise, it is necessary to block the noise using the fixed objects. 22 13.

Use the serial communication program provided by CanTops to enter the commands. About A Serial Command Setting for Different Modes Master Mode Slave Mode Setting the No. of OHT, communication medium, ID, CH, and No. of PORT is only possible when SELECT is ON (Communication prohibited). Other commands can be used at any time through the serial communication. Serial commands can be used at any time, regardless of SELECT status.
